Make it stop and go around corners... that makes a good track car.

"driven" has some good suggestions above, but remember that to make the most of r-compound tyres, you'll need more camber and castor than with road tyres to make the most of them at the track... alot of people forget that you need to be more agressive with your alignment settings if you run semis.

If you haven't had much track experience - stick to standard road tyres... and you don't need alot of mods to hit the track. Get out there and learn the car first, and then when you've got you head around it, then you can tweak it to go faster round the track!

Have fun!
