You should have a 3 bolt rear-end, count the number of bolts on the cups behind the tire and that will tell you, as far as rpm to launch I have repeatedly launched at 4500 to 5000 rpms with out any trouble but it all really just depends on how often you drive the car like that. I believe that the 4 bolts can hold up to like 600hp but i am not to sure on that.

The ACT 2600 has the grip to break the 3 bolt rear end IF you get too agressive with the launch. Rev to 4500 and do a fast slip and it should be fine. Others have reported doing hard 5500 rpm launches on the 3 bolt, but that's pushing the limit. Just don't dump the clutch.
