I second what Mark says. The M6 is not much better on the track than the 650i. They are both way too heavy. You will rapidly burn through tires, brakes and suspension bushings due to the weight.
The 6er is a very fast and capable car on the track; my 650i is only a few seconds a lap slower than my heavily modded M3, but I can only do about 5 or 6 laps before tires and brakes are overheated where the M3 can run all day long without a break on the track.
Straight lines are for fast cars...turns are for fast drivers
'04 M3 - track
'06 650i Cab - daily driver
'02 Highlander - kid hauler
'01 330Ci - winter beater
