I've done 122 mph in my mazda 6 , have a Injen cold air intake and a custom monza exhaust and my warranty is still valid for another 45,000 miles =)
Anyways, If a clutch is fried, It's been beaten. If you're worried about OEM parts, Buy a aftermarket stage 2 clutch and be done with the clutch thing for good. That doesn't mean beat the living hell out of the car either =P
