I'm running 205-40-17 Kumho's on 17 x 7.5 Kosei k1's set @ 36 psi cold. The car is box stock otherwise. DSC was off. The track configuration we ran @ Buttonwillow was clock wise and about 3 miles in length. After 4 hard laps on a (finally) dry track we checked temps and pressures. Here are the results:

LF:
Pressure: 50psi
Temps: inside: 165 center:175, ouside: 175

RF:
Pressure: 50 psi
Temps: Inside 171, center: 171, outside: 167

LR:
Pressure: 46 psi
TEmps: inside: 138, center 142, outside: 137

RR:
Pressure: 45 psi
Temps: inside: 118, center: 118, outside: 120

There is a very long 4th gear right hand sweeper that probably accounts for the left to right differences. Camber has never been checked but looks to be a lot closer to ok than I would have suspected.

 

What did you pay for the tires BTW???
And where did you get them? I am
switching out Yokos and want to try
something new. Thanks.

 

I bought the Kumhos from the Tire Rack along with the wheels. I based the selection on price ($94), Tire Rack test results, and user reviews as reported on the Tire Rack site. I'm probably not the best judge since I have no previous experience with a front driver or max performance street tires. My previous car was a 1976 Pontiac Winston West stock car that we ran in vintage races for years. However, I am VERY impressed with both the wet and dry grip! Also, the tires have no surprises waiting when you approach the limits. This is probably a function of the MCS more than the tires but I found that a slight amount of throttle lift when the front began to push freed up the rear and in very little time I was using that to steer the car right to the exit berm in corners where I couldn't get front grip. What a gas!!!! First mod will be a limited slip differential.

 

I have heard a bigger rear sway bar will accomplish what
you are looking for from a limited slip. Thanks for the
info. My swaybar goes in this week and next track day is
4/19. I may give those Kumhos a workout...
Talk to RandyBMC as there are no warranty issues with
the sway bar. Recently, at Daytona, a Mini was DNF due
to a blown LSD...don't know which one though.
