  1. The dealer is so full of it if what you are saying is true. Have the checked the brakes themselves to see if brake force distribution is equal (ie one pad being too strong with its force)? Also the brake lines (could even be something stupidly simple as air in the lines). Chances are the brakes themselves are the issue.

    Any suspension issues? The wheel alignment would mask this issue

  2. Agreed and then there are the others who think that its a F#$%*ng GRAND PRIX and they will overtake you anywhere (even on a chicane) as they think that they will be on a podium with a bottle of champagne with 3 bikini models at the end of the race.

    Hehe yep!

    I once was trying to get past a HSV of some description I had him for straight line speed and was infinitely quicker in the corners. Problem is he was all over the shop and it wasn't worth the hassle taking him under brakes because I didn't trust his ability

  3. ^^^ What Danny said. This is why I don't do full on race days any more, just happy laps. If I destroy my car, I'll be depressed. If I destroy my car AND a Ferrari next to me, I'll be depressed AND broke....

    The worst thing about track days are the newbies who think that you are actually racing and don't follow common courtesy and let faster cars pass.

  4. I think so, it is factory recommended viscosity, however i've seen people using 0-40W just so their engine oil can last longer, none the less always asked your dealer if ur not sure, good luck!

    Who told you this???

    The broader the viscosity in oil the less stable it is and the shorter the lifespan. 0w40 will give you more protection as it is suited to run at colder and hotter temperatures than 5w30 BUT it will not last as long as the 30 weight oil.

    To be honest though unless you're tracking your car the above wont be issues. Oil degradation happens as a result of time and heat cycles you put the oil through. If you change your oil regularly don't stress too much about this. The best thing you can do is ensure you change the oil regularly.

    Play around with oils and see what works. In my WRX the recommended oil was 5w30; I found it ran smoothest on 10w50 semi synthetic. It was stock so there was no need to go such a heavy weight oil but it worked. If you are going an overly heavy oil also make sure you warm the car up properly; the cushioning of heavy oil comes at a price - long term, it can lead to pressure problems if the oil isn't properly heated

  5. ^^new car prices have not changed that much in actual dollar terms for quite some time. If you look at new car prices relative to wages the cost of a new car has gone down. Issue is that because there are so many new cars on the market and they are affordable it has taken its toll on the used car market

  6. Wakefield is an interesting track in the sense that your fast laps don't actually feel fast; smoothness is the quickness to being fast there.

    Nah mine's a GTS-T so everything goes to the rear :-)

    What's the Eastern Creek thingy? Lexus didn't send me anything for that (and I ticked motorsport as my primary interest) so I'm assuming it's for ISF owners only?

  7. Yeah Wakefield is a technical circuit, so heavy cars and high power cars aren't the greatest on there. Give Eastern Creek a go, would be much more suited to an ISF.

    That's pretty good and a lot tidier than the previous video. The other good news is you can take a fair bit more time off what you did. The biggest pointer is in pretty much every corner you're braking and turning in too early; the other is that you can spend less time transitioning between accelerator and brake. Go wider to the edges of the track and turn in later.

    Probably some key corners for where you can pick up a lot more speed:

    1. Through the kink, stay near the pit walls and at the very end of the wall then turn in (it's a bit later than where you are). Here I would dab the brakes to wash off speed and get weight over the front end, turn into the kink then stand on the brakes between end of the kink and the corner.

    2. The corner before the fishhook, go wide to the right then come in, you are staying on the kerb and losing speed to the fish hook

    3. This one is the easiest to do because it's easy to explain. For the last corner brake at that 100m marker, that should get you deep enough to get the line right into the final corner. Ignore the 100m aspect of it and trust your brakes on this one (you'll be fine).

    The 350 F Sport is a daily drive and my toy/track car is an R33 GTS-T (albeit a road registered one), bit over 450hp at the engine, torque curve flatter than an A-cup, 1300kg's and not an electronic aid in sight - WICKED, intoxicating fun! It's not running right because it feels restricted, I think it could be clutch slip because it doesn't feel like the power is all there even though it's making the right noises.

  8. Wow looking at that sheet I'm surprised to see the ISF so slow around there. I was expecting of to be slower than an E90 M3 but not that far off the mark.

    Yeah post it up, be nice to see how and where you've improved with the times. I'm curious to know how much quicker you will be with an LSD. I'm happy to come just need to find the time though. Unfortunately I won't be in an F, I won't even be in a Lexus

  9. No Worries,

    It was really great today there were only SIX cars there all day. Had the track for myself as long as I wanted so it was a great opportunity for testing.

    The tires were just excellent. Did approx 6 seconds faster compared to the previous tires. My best today was 1:14:07 and would have done well below if I didn't run out of fuel. That is 2 seconds off of the official ISF time on this track driven by a v8 supercar champion.

    It was great fun again. Love the car.

    6 seconds a lap is awesome - congrats on bringing down that time so much! Great feeling taking so much off your time huh?

    Out of curiosity where did you get that Lexus lap time from? It's actually a slow lap. When I used to Supersprint the quickest guys in street cars were running 1.08's give or take. I would be capable of 1.10/1.11's and the bit slowing me down was well me. These were from weekend warriors doing it but driver ability being equal those cars would be faster than an ISF around a circuit. None the less when you factor in ability of a professional driver I would imagine the ISF to go around the 1.07-08 mark at a guess.

    PS I had a look at your video on page 1 and some pointers I can offer you on where you can pick up speed in:

    1. The kink at the end of the straight, turn in just after pit wall (dab the brakes to get weight over the front end).

    2. Your approach down the hill, there's a lot more room for you to go closer to the apex's. Turn in later than you were. This section here if you feel like you're dancing with the car through here then you've nailed the balance.

    3. The second corner off the top, it was good you changed it to 2 corners and not 1 like in your first run. To go faster just dab the breaks going into the second right hander, turn in later and be more progressively aggressive when powering out.

    4. To the fish hook you can make up a lot of time turning later here, line for exit speed is best through here.

    5. Stay off the ripple strips - they seem to slow you down by unsettling you.

    Hope this helps and can make it out there soon!
