Unfortunately we had a problem with the M3 that caused us to park the car on Saturday. Had a much better weekend in the Swift DB2. Here's the link:
3 times each lap you are at max velocity, max revs, and max load. Then you plant the nose and use max engine back pressure as you slow the car.Bummer about the M3.
"Road America which is a motor killer" ?!
Why or how? Currently in a motor 'refresh' process and taking preemptive measures for durability.
