these cars are MADE for the track!! i couldn't imagine NOT participating in AutoX or DE while owning one. i can understand warranty concerns, etc. i'm an immediate gratification kind of guy, though, so those thoughts exit my mind the instant i pull out of the pit.
bmussatti - if you're concerned with the broomstick rule, there is a kit you can buy that lowers your seat by about 2" while still allowing it to slide properly back and forth. i think brey-krause makes it.
alternatively, you can go for GT3 seats or a brey-krause roll bar extension (or you can just scoot the seat forward, lean the seat back, and scrunch down for tech inspection
)
