?uestlove... your handle looks familiar. Were you part of ALSC/SC?

I can tell you that the 19x8 and 19x9.5 combo would fit perfectly on the car without scrubbing or having any tyre fitment issues. 225 on the front and 275 on the rear would be pretty sweet. It's odd that they don't offer a 10" wide for the rear, as it's going to be the widest wheel that would comfortably fit under the guards without any modifications. As for rolling the guards, the down side is that all of the plastic/carpeted wheel wells won't line up anymore and may sag down if not tied out of the way. I'm not trying to put you off with any of this, I just know what fit onto my car and the tolerances available with the IS250. If you're planning on the IS350 brakes, you better make sure that the wheel design can accomodate them. The spoke design will need to be shallow from behind to allow the caliper enough room. I shopped around for 6 months to find a set of wheels to fit over my 4 pot Supra brakes on my last car :(

Okay, the 19x8.5" +42 should be fine on the fronts. Is +38 an option? I have a vague memory of a suspension bolt sitting very close to the wheel on the fronts, and 38 will clear it. 42 might be a bit close with a 8.5" wide rim. If you can only get the 10.5" rears, get the highest offset possible that is closest to +40, in your case it seems to be +22. This will make the rear wheels stick out from the guards, so you'll need to get the guard pulled out about 5-10mm unless you super stretch the tyre with a 235 or something. Just be careful with such a stretched tyre. It might work on all of the baller cars in Japan, but remember that their roads are far better than ours, and you have a greater chance of popping a bead off the rim if you hit a nice enough pothole. The wheel will also be very exposed to gutter rash, so just be careful when parking etc.

19 x 8.5" +42 offset should be fine. I can't say about the rears. I think 10.5 might be too wide for the car without "adjusting" the guards. If you are set on them, +22 would be a better option than +15 which will stick out the sides of the car pretty savagely. Best of luck stretching a 235 onto a 10.5" rim. It's far beyond legal or safe limits.

My thoughts are that the fronts won't fit without serious altering of the inner guards. 8.5" wide with +38 offset (what I run up front) and 245 wide tyres scrubbed every time a corner was turned. Changing for 225 wide tyres fixed the issue. 10.5" wide on the rear with any less than ~40mm of offset is going to cause scrubbing on the guard and suspension. In my opinion, slightly too wide (10" would be the most comfortable width without having to mod anything else) and try to stick to an offset between +40-50mm. Only speaking from experience on my own vehicle. Others may have tried more combinations with other results.

Not lowered, but by the looks of it, it could be lowered 2 inches without too many worries.

I run 20x10" on the rear of my IS250 with 275 rubber and no scrubbing. All about the offset!

Just thought I'd share a video of this crazy beast:

55W is high beam power... are you sure you want that kit?

Ahh, someone beat me to it. I grabbed a copy of the wiring diagram a while back and figured out how to get this happening, but never built anything. Great to see someone worked on it.

You'll love it... great mod :)

Illawong Bay/Ku-Ring-Gai Chase? There's a BBQ area there and heaps of parking for a meet. Illawong Bay

Surprisingly I have every Saturday in December free at this point in time... Keen on another meet :)

+1 for this. Manny & I imported the pads from the USA and I have loved every minute of them. No more dust after a loooong time without a wash, and much better progressive feel.

My rotors were gone at 17,000km. They are very soft on the IS. Generally a worn disc won't cause squealing, but a glazed one will. Check for shiny spots which are out of the ordinary.

My suggestions are for an IS with standard suspension without lowering. I haven't lowered mine, so take that into mind if you plan on installing similar sizes onto a lowered vehicle. Fanel: Those wheels should have no problem at all fitting onto an IS, even a lowered one. Width and offsets are excellent. Is your IS a Prestige or SL? Does the SL even support TMPS? If it's a Prestige, zero worries as it doesn't use TMPS.

I'm running 10" wide on the rear with +45 offset and 275 wide tyres. Zero scrub.

+45 offset and no wider than 225 on the fronts.

My 20s don't rub at all: Front - 225/30-20 (20x8.5 +38 offset) Rear - 275/30-20 (20x10 +45 offset)

Mine were gone before 20k... I will be complaining about them at my 2nd service next week.

Just disconnect the battery for 15 minutes and don't worry about the dealer. We used to do this in the Soarer club all the time. Not sure if this will work on the IS, but in the Soarer you could just pull the DOME fuse for 15 mins instead of disconnecting the battery, and you wouldn't have to reset all of the crazy features which hate power failures.

I've had my '09 IS250 since new... just on 2 years old and the tyres are still 80% tread left. I have the 17" option wheels. I don't drive like a grandma, nor do I thrash the car. Perhaps the previous owner chewed through them for you?

Don't worry, Danny will probably bring another M3 :P

Those will fit on the rear with no problem. Forget about them fitting on the front with that width though without some serious under guard modification.

MY09 here... remote buttons will lock & close sunroof/windows or vice versa. Didn't have to ask the dealer to change anything on the fob, unless Sutherland have finally proved their worth and did it without asking.
