Need a little advice:
Have a good friend that is running Wissota Super Stocks.. Problem is, can’t seem to ever get the Left Rear hotter. He did better this last week but still doesn’t look right. Here’s the numbers:
Weights are 637 LF, 606 RF, 906 LR, 669 RR.
Chassis Heights 8.25” LF, 8.5 RF, 8.25 LR, 9.5 RR
Diag 53.6, Left 54.7 Rear 55.8 For a total of 2817 Lbs.
Running the required A 40 Hoosiers
Going out with Tire Pressures of 11 LF, 13 RF, 12 LR, 14 RR
Came in after 8 LapHeat with pressures of 10.5 LF 13 RF, 11.5 LR, 15 RR with Temps of 112,124,116 LF and 104,104,109 RF and 114,103,111 LR, and 153,155, 156 RR
Running ˝” rear stagger on a 3/8 to ˝ mile with fairly high banks. Track was very dry for the heat race. Compisition is sand and clay..more sand than clay and dries out to black every feature

Kinda new so if anybody can provide some possible options/suggestions that would be great, I can provide more info if needed.

Thanks

I had this problem a long time ago with a car. The best way that I found to fix it was I took all the stagger out of it it will be a little tight on you in the center and off put you can also adjust that with a lighter spring on the left rear to comopisate for that.

first of all i would suggest the following -
go down a pound on the left front, increase camber maybe 1/2 degree on right front,go up a pound on left rear, and dont touch the right rear. increase the left rear spring pressure by 50 lbs or add a spring rubber. this will balance out your setup just a bit and force the left rear to carry more weight thru the corner which should increase the tire temps a bit. it may tighten you up some but you can go up on stagger to loosen it back up. you should be very close as it is. these changes will help. if you look at your figures you will see which tires have too much air and those that dont have enough. you will also see the right front outer edge is working harder than the middle and inside therefore i recommend the camber gain.

LF and LR must have a small leaks after 8 laps they had less air.
