THe record for the exedy twin HD that I am aware of is a good friend of mine. 71K on it.

330/330 car on BR's dyno. Great running car - Daily driven, and decent amounts of spirited driving. Prob 50/50 on the highway/city milages.

 

yea if I was street driving my car I could probably get close to 60-70 out of a clutch.. I kno my car see's track time, alot of track time. I dont drag race I road race but it still does a number on transmissions and clutches

 

this all depends on how you drive your car. and how much TORQUE the car is making. my car is pretty stock power and torque wise, but i have an upgraded tranny and t-case. but im reading up and if you launch the car efficiently (under 2,000-1,750 rpm and quickly) and dont power shift, then u have potential to make that thing last 80,000. i know NSX guys who use stock clutches, go to track events, and daily drive, and managed to make their clutches last an amazing 90,000miles
