I'm experiencing understeer in tight turns while autoxing, here's the setup on my '97 E36M3:

TCK SA Koni coilovers with springs 450/500lbs f/r, lowered 1 inch. Shock settings are 1 1/4 turns from full stiff front, 1/2 turn from full stiff rear.

Eibach swaybars, set at soft/medium f/r.

M-F camber plates set at -3.5 degrees, with rear camber at -1.5.

Front toe is set at zero with C/Ps at -2.5 degrees (street setup), rear is 1/8 degree toe in.

Tires are 255 Victos on Kosei K1s, with cold tire temps at 35/33 (warm temps 38/36) f/r.

So should I crank the CPs to full negative, or play with tire pressures or s-bar settings?


TIA

For auto-x definitely crank the CP's to full negative.

Try front camber of -3.5 and full stiff on the front bar.

And brake earlier. :D

yeah, I need to do that too...:D

You may also want to play with lower tire pressures, yours are pretty darned high for AutoX. With 710s we are using pressures in the 20's and low 30's. Vicotracers like a little more, but I would suspect you might be faster in the low 30's. Play around with it and see.

Might be a good idea to pick up a pyrometer also as that will help you dial in both pressure and camber.
