This is only my 2nd time driving my M coupe at SOWS, both times being ccw. The first time was almost 3 years ago back in Sept 2009, during which I ran a 1:29.2xx with stock tires on KW V3's. This time, conditions are very similar at 90*F, but I have added a few more modifications to my car (Stoptech BBK, Hawk DTC 70/60 pads, uprated spring rates 10K/12K, 18x9/18x10 wheels, Hankook RS3 tires, Recaro SPG seats, CSL headers, light weight battery). I was able to run a 1:26.5xx in traffic with these 5+ day old tires. Pretty sure I will be able to shave another couple of seconds with a fresh set of RS3's in cooler conditions. Stay tuned!
