_ISF

Contact Lexmania who are Lexus wreckers im sure they will have one - unless you want a brand new one that is. https://www.facebook.com/LexmaniaAU/

Cheers mate - new pics added which were taken late yesterday afternoon. Some of them are a bit dark so ill get some more this coming weekend with better light.

Thanks mate - yes i would really like it to go to an enthusiast who will continue to look after it in a similar manner.

Lag in the turbo setup or the build?

IS250C's come with 2x front sensors (as does my ISF).

I recently purchased Falken Azenis FK510's which are a good chunk cheaper than the Michelin PS4S and perform 90% as well. The Falken's have performed well in multiple tyre tests both locally and overseas. See some info and feedback here:

**Deposit taken 24/7/19** Hi Guys, I have decided to sell my IS-F after owning it for 2 years and about 10,000km. I have enjoyed my experience of owning a JDM V8 and also enjoyed the reliability of a Japanese vehicle after owning several VW and Audi's in recent years. As a car enthusiast, I have a list of cars that I would like to own - so I am selling the IS-F in order to buy another car i have always liked. Build date: July 2011 (so it has the factory LSD, more compliant suspension, revised dash cluster with the big tacho, and updated headlights) Exterior Colour: Ultrasonic blue Interior colour: Black leather with blue stitching Kilometers Travelled: 54,000km Registration: 12 months NSW rego (expires 25th June 2020) Engine Modifications: RR Racing ECU tune, customised Xforce Varex exhaust with Smartbox, AFE panel filter, HPS intake hose Power: Makes 265kw at the wheels with the current setup (i have dyno sheets). Stock was 235kw at the wheels. Exterior Modifications: VLand tail lights, Front grill plastidipped black to remove the ghastly chrome, 15mm wheel spacers (good quality German made spacers, not cheap Chinese junk), BaysonR front lip, Carbon rear window spoiler. Windows were tinted shortly after i purchased the car in 2017. Service records: The car has been over-serviced since my ownership, but with it's original owner it has missed 1x service. Brake disks and brake pads were replaced just after i bought the car so they are approx 10,000km old (DBA slotted and drilled rotors and Bremtec pads). Diff oil replaced December 2018 (genuine Lexus LSD diff oil). I have done 5x oil changes in the 2 years i have owned the car (1x official mechanic log book service and 4x DIY oil changes). Cons: It has missed 1x service with the original owner, but i have over-serviced it since my ownership with all services photographed, documented and receipts kept. It has also had 1x official log book service since my ownership to keep the log book stamped as appropriate. There is a small mark on the bonnet where it appears a bird poo was left on for too long by the original owner. I have always intended to have the bonnet repainted but never got around to it as its just a small cosmetic blemish. The car has been extremely well looked after under my ownership, always driven like a baby for a good 10 mins until everything is nicely warmed up and always hand washed and polished/waxed on a regular basis. Only driven a few times a week and kept in the garage at home when not being driven. Serviced every 6 months despite only having been driven about 3,000kms in that time frame. Brand new tyres fitted on the front about 6 weeks ago, rear tyres have another 5,000-7,000kms in them. Nothing beats the beautiful sound of this Japanese V8, and with the addition of the Xforce Varex exhaust and intake it makes it even better. Plenty of power when you put your foot down, and docile when you're driving around town. Fuel economy varies depending on your right foot of course, but expect around 9-10L per 100km on the highway, and around 16-18L per 100km around town. This car has been 100% reliable since i have owned it and never missed a beat or let me down. The aftermarket exhaust (which has cost me about $4k all up) fitted and customised to suit this car can be adjusted at your wish to be almost as quiet as stock, or you can open the valves and have the V8 roar. The Varex Smartbox system fitted to this car also allows you to fine tune the sound and volume of the exhaust to suit your preferences. $51,490 ONO but I am open to sensible offers and would love for it to go to another enthusiast. Message or call me if you have any questions. 042two 2four7 eight31 I would prefer to sell the car as is, but can remove the exhaust and certain other items if the buyer does not want these items.

What do you not like about the Potenzas? Are they noisey, wearing out too quickly, dont like the way they look, too expensive to replace etc etc? Whats your budget? What size tyres does your car use? This might help you pick a new set, although these are mostly high performance tyres which aren't necessary on your car: https://www.msn.com/en-au/motoring/research/motor-tyre-test-2019-finding-australias-best-performance-tyre/ar-AADmUvi?ocid=spartandhp

Yeah I am struggling to believe the toe could have been that far out (7.6mm) because I've only driven 6,000km since my last alignment and haven't hit anything or changed any suspension components etc. Also the car only has 53,000km on it so all the factory bushes etc are still good and i have the Figs Engineering control arm bushes. So unless the previous alignment was also crap (different place did the last one) then something does not add up. I still have my previous alignment printout so I will check that out. I did recently change my front tyres, the old ones were shagged on the outer edge but still had approx 4mm elsewhere...but in saying that these tyres were on the car when i bought it and i could see they were already worn more on the outer edge.

Thanks for that - i have downloaded to keep with my records. The beauty of forums is that this info can be found months/years later, whereas with Facebook groups its lost and there is no search function etc so you get people asking the same questions over and over again.

The hi flow cats in my car are less than 1 year old and are lucky to have done 5,000km. I paid a small fortune for them as they are the stainless steel cats with metallic cores, not the cheaper ceramic ones. So they better not be buggered!! I am well aware that the E20-30 blend will lean the Air/fuel ratio mixture out somewhat, but my car has always run a bit rich under load so i figured that leaning it out a wee bit wouldnt be an issue - certainly not for a short term test like this anyway. BP Ultimate 98 is what i always run in my cars and have done for years, it was just with this experiment i was blending BP98 with Caltex E85. Anyway, im happy to end my experiment and move back to straight BP Ultimate 98.

I literally just got back from paying them a visit to discuss. I was hoping to get some feedback before i went down there but this forum is so dead haha. I spoke to the guy at the front desk (same guy i dealt with a few days prior) and he agreed that they had selected the incorrect car. We went out to the alignment bay as the technician had just finished aligning an Evo 10 and had a look on the computer. The IS-F is indeed listed as a separate car to the regular IS250, LS400 etc - so it was just either lazyness or an oversight by the tech on the day for him to select LS600H. They have agreed to re-do the alignment at no cost to me and fix up the steering wheel alignment too by adjusting the tie rods. I have attached a printout of the alignment info, but they do adjust camber and caster as well as toe by the looks of it.

Just updating this thread - i recently bought 2x new front tyres, and went for the popular 245/35/19 size. This feeling in the steering at low speeds during sharp turns is drastically reduced with the new tyres.

OK so my car was due for a pink slip this week and i generally get my alignment done at the same time each year. So this time was no different so i booked in for both pink slip and alignment at my local Bridgestone tyre place which is conveniently located about 400m from my house. I told the guy at the front desk the car model details as i handed him my keys, and specified that the car is an IS-F - not an F sport or regular IS250/350 etc. I also told the guy that since fitting new front tyres about a month earlier i had noticed my steering wheel was ever so slightly off-centre (probably 10 degrees off) when driving straight down a road, and asked if they could fix this while doing the alignment. An hour later when i picked up the car, i paid and got my invoice, pink slip and alignment printout. I jumped in the car and took a quick look at the alignment printout and noticed they had selected the car as being a Lexus LS600H. Im no alignment specialist - in fact i know very little about alignments despite being a car nut....but i can only assume that if the operator selects the incorrect car that the alignment will be setup for that same incorrect car - therefore im driving around with an alignment suited to a luxury car and not a sports sedan. Now obviously a LS600H is a very different car and no doubt has different alignment settings to an IS-F. On top of that, my steering wheel is still off centre. So i will be going back this week to get them to fix up the steering wheel and also wanted to talk about the fact that they have the wrong car listed on my alignment paperwork. I walked past the shop about 30mins after dropping the car off and it was on the alignment machine and up in the air - so im assuming they did in fact do an alignment. I have always had cars that are somewhat rare, and have noticed on other alignments i have had done that they have picked the wrong car (correct brand but incorrect model). Does it really matter? Has anyone else had a similar issue? What did you do?

OK so i am giving up with the E85 blend project. I worked my way up (starting at E15, then E20, then E25 etc etc) to several tanks of E30 blend over about 6-8 fill up's. For my type of driving the difference (which isn't much to begin with) is just not worth the atrocious fuel consumption (22-24L per 100km) and inconvenience of having to visit 2x separate petrol stations each time i fill up. If i ever take my car to a track day or drag strip etc i would probably use the E30 blend again, but now everyday street driving in a relatively stock IS-F it's just not worth it in my opinion. Also to note - on Saturday morning i got a CEL and the car went into limp mode (takes off in 2nd gear etc) the error was a cat efficiency code. Not sure if this code was partially brought about by the E30 blend? I was driving sedately at the time as the engine was still warming up and i had my daughter in the car. Although i do occasionally get a similar error code (despite RR Tune and also RR o2 conditioners) its a very rare occurrence, so im wondering if the E30 mix might have had something to do with this. This was the one and only CEL or any other issue i had while doing this experiment.

The manufacturer is usually embossed on the caliper. Pop a wheel off and have a squizz.

I agree on both the wheel choice and the front lip. Looks really nice and classy. I wish i had known this lip existed before i purchased the BaysonR one.

I know exactly what you are saying. Regarding "wife mode", your wife can also download the Xforce app on her phone and then she can make the exhaust quiet if that's what she wants - i have shown my wife how to use it (very easy). I have in previous years owned cars that Police targeted (i had 2x Nissan 200sx's about 8-10 years ago) but with my last few cars (Golf R and Golf GTI) as well as the IS-F they don't even look at them........part of that might be down to the fact that i now keep my cars looking stock-ish on the outside. Although in saying that, all my cars have been very subtle and very tidy compared to what you see around.

If you have the PPE's then perhaps you might like to play with the Matrix mode. That way you can have the valves partially closed at idle and low rpm to keep it relatively quiet, and then once you go past a certain rpm or throttle position they will open up fully to give all the noise. The Matrix mode is endlessly adjustable so you will get it to a setting you are happy with and then no need to stress out when you see a cop.

Funnily enough i saw the add for the Sparesbox 20% sale this morning and was going to let you know - you beat me to it. You prompted me to check my invoices from Sparesbox and i actually paid $498.95 for the Smartbox when i bought it in January (that was with a $100 discount). The Varex mufflers were $400 each (after discount) and i must have mixed the price up when i posted in this thread earlier. As for connecting it all up, i removed the Varex box and remotes altogether and have just kept them in the garage as a backup in case the Smartbox fails etc. You do not need to keep the normal Varex box connected unless you still want to use the remotes to override the Smartbox. So the existing cables/plug you will have that is connected to the motors on the mufflers will connect straight into the Smartbox. The OBD connection is only required for the Matrix mode as far as i am aware. The manual mode will work fine without the OBD plug connected. I have not tried the Geo mode (yet). As for mounting the Smartbox, i decided to mount it behind the drivers side foot well kick panel where there is enough room for it to mount. I also hardwired mine in (you need to install an inline fuse with a 7.5amp or 10amp fuse to protect the Smartbox in case of power surge) just last week because i got sick of the power cable being plugged into the cigarette lighter and it looked messy. Its a nice neat install now.

^ that's pretty impressive. I wonder how much of a part the Gyeon products plays in that result? I just cant get over the cost of the Endless pads!!!

I do 6 month oil changes on my cars (overkill perhaps, but cheap insurance to know the oil is clean and not contaminated) and it was time for another one over the recent Easter/Anzac break. Its super easy to do a service on this car, no need to remove the whole under tray as they designed little windows that unbolt to allow access to the oil filter canister and sump area. A few months prior i had access to a hoist for a short time (at the Lexus dealership my brother works at) so i changed the diff oil and brake fluid while i had the chance. In hindsight i should also have done the engine oil at this time because of the convenience of having the car in the air....but it wasn't due yet. I love how easy and straight forward this car is to work on - no special tools needed for anything, parts are cheap and readily available too. The most expensive part is the oil, as the sump holds about 9.3L so i alwasy buy the oil when its on sale at Supercheap or Repco etc and either grab a 10L drum or 2x of the 5L bottles depending on which one works out cheapest. I was due for some new front tyres as these cars are well known for wearing the outside edge out prematurely (soft lower control arm bushings). After researching tyres i decided to go with the reasonably new Falken Azenis FK510's which have rated quite well in multiple tyres tests both locally and overseas. The IS-F is a bit under-tyred from factory so most people throw a wider tyre on the factory rims. Stock tyres are 225 up front and 255 at the rear. I have now gone 245 on the front and will go with 275 on the rear in a few months once i finish killing whats left of the rear tyres. Happy with the Falken's so far, very grippy, quiet, let you know when you are pushing the limits and they have a nice looking sidewall too. The wider tyre looks better on the rim and fills out the guards just that bit more too.

Wow that's a good price for the EBC Redstuff pads - i have seen them advertised previously but were much more expensive. I was looking into those Endless pads the past few days, but for that price they would have to be a VERY special pad....i don't know if i could justify the insane cost unless there was some sort of group buy discount etc. I think i might try the Project MU NS400 next - i was talking to a few guys who were running those pads at the recent Sydney Lexus F meet up and they all said they were great pads with low dust. I just want a pad that will dirty the wheels in the same speed the car itself gets dirty - im not looking for a magical no dust pad.

Heres what you need. $6k for a running engine, gearbox and all wiring/ecu is a bargain.
