When you do that ABS and DSC turn themselves off. my dash and NAV actually were lit up like christmas. it was surreal. Lesson learned - don't track with PSS (or any 300 tread wear tire for that matter) when temps are hot.

i did a 1:38.1 lap when it was 80+ degrees out before lunch...but when i went out after lunch it was 97 degrees and the track temp neared 150 degrees, i should not have gone out there with street tires. I couldn't break 1:50 as I was sliding everywhere.

A prius with R-compounds could have been faster than me.
Well yes, PSS are not track tires. I didn't know you had that much power... You need RS3s at the minimum man, if not TDs! PSS are great for a DD tire, but not to track with 600hp on a hot day!

I didn't know you had that much power. damn. that much be killer at big willow for T8 and the straight.

I always run my RS3s ~36-38 hot. usually drop the driver side about 2-3 psi lower (so like 26-28 cold depending on the temps that day) than the passenger side due to T8. I miss big willow....

Depending on my mood, I turn DSC off, so I wouldn't know about those lights going off. I can't imagine having 600hp and not making DSC go crazy lol.

ABS only gave me an issue at ACS after I had installed my Stoptech Trophy BBK with Endless MX20 pads. I wasn't used to the bite and kept causing ABS to kick in. took me a little bit to get used to it. I miss those pads... they were loud, but they stopped so well.

My fastest time in my e93 was only 1:36. All my friends who were around mid to high 30s are all now in the low 30s. I have fallen behind :/

I did a 1:51 in a friend's stock 528i with runflats! lol. that was one extremely comfortable track day
