38 hot is our target. When i came in after pushing for about 10 laps, the tires were greased to hell near the end and pressure was at 43. Felt like driving on ice.

I have always run 15x7 Kosei K1 with 205s in spece30 (toyo RA1 and R8eight) and in a couple of Chump races (Rivals). No complaints on any of them, but on the long carousel turn at Atlanta Motorsports Park last November, it seemed clear that many of our chump competitors had more ultimate cornering grip than us. The e30 was great in transitions, great under braking, and relatively strong on straights, but in that long steady carousel I could see the gaps open with many cars I was chasing (faster and slower cars).
I am just thinking (hoping) that 225s on some 15x8s will give us a bit more cornering grip..
As for tire pressures, I have never been able to scientifically test what is ideal. I usually start at 28.5ish on outside front and 30ish on inside rear (cold) with any tire I have run. I sometimes add or subtract a bit to get around 36-8ish hot all around, but really, I have no idea what is best.Last edited by GillesBigCowboy; 04-17-2015, 05:05 PM.

I've decided to go with these http://www.tirerack.com/wheels/Wheel...5&autoModClar=
and run 225/45/15 RS3 for now. We can't run spacers so this should do the trick.ChumpCar and 24 Hours of Lemons racer. Subscribe to YouTube channel with my E30 race build, 1M and 280hp Nissan 240SX track build in progress.

I have RS-3s (225/45/15) and TRM C-1s in 15x8 on my S52d E30. I'm lowered on Vogtland coils and had to roll the rear fenders. No issues with rubbing. It's an awesome setup that I think you'll really like for chump. I second watching the air pressure. I can post a pic of the car if you want to see it.sigpic
