1999 BMW E36 M3 with S54 (328 whp SAE5) at 2500 lbs with fuel and driver. No aero, narrow body and 245/40/17 Hoosier A7 (3rd event). Was fighting a fueling issue all morning but got the car sorted in time for the afternoon sessions and was able to put down a few decent laps. This was my second event since the S54 swap along with new suspension setup and MK60. Car feels amazing but might need to make some adjustments for the high speed sections. Looked at the data and there is a 1:49 in the car with fresh tires so maybe next year I can join the sub 50 club!
