1999 BMW E36 M3 2475 lbs with half tank no driver. Stock S52, no aero, narrow body and 245 Hoosier A7 with stock gearing (3.23). Went out first session of the day on new slicks with temps in the 60's so it was perfect conditions to set a new PR. Did a 1:53.40 followed by a 1:53.36 to back it up. Both car and track were perfect and allowed me to put down a run good enough for first place in Bimmer Challenge B3 class. Let me know what mistakes you see so I can chase down a 1:52 in December!
