Hey thanks for the postive feed back , hey Harry did you see the spilts , the car felt a bit nervous going through the last few corners before the finnish and it looks like from the times thats one area that can be improved , i couldn`t beleive how much crap was on my tyres when i got them off the car .. looks like you need to clean then between runs , I recon there are gains with making the rear end work a bit better .. I was using one of " Top Gears" H190lsd`s with a 5.1 diff and taking off in second. which worked out great .
