What needs replaced with the clutch I'm getting ready to put in a new clutch on my 99 FRC. It has 91k mile on it, and I'm not planning on making more than 400 RWHP any time soon. I'll be on ET streets for drag racing.
I think I've decided on the LS7 clutch.
First, do I need a new flywheel, or can I have mine resurfaced?
What else will in need/want to replace? Pilot bearing, slave, master clylinder, or what????
I've heard of doing a drill mod for the corvette hydraulics? Is it necessary, or can I get some other year hydraulics, or what?
Seems like I've read this or that on everything and haven't found exactly what I'm looking for.

I recently did the LS7 clutch swap in my 01 Vette and it only had 27k on it. About 3 months ago I did a head/cam swap and went to 432 rwhp and 400 rwtq and the old clutch wouldn't shift at high rpm.
I changed out the whole hydraulic system with new 04 Z06 m/c and slave. Do the drill mod while you have the hydraulics out. The restriction in the Vettes is in the slave clylinder line. The old slave was badly worn and I was really surprised since it only had 27k on it.
I got a remote bleeder line from steve d on this forum. Get one, it is worth it to be able to bleed or flush the system from underneath the hood instead of under the car in a hard to reach location.
You have to get a new flywheel with the LS7 setup as yours won't work. You can get a new LS7 setup for around $400 if you look in the right places. You still have to buy the m/c, slave, pilot bearing, and remote bleeder. I changed mine out myself and it is such a PITA I only wanted to do it once is why I changed everything out.
So far the LS7 clutch has worked great. No chatter and can shift it at 6500 rpm with no problem.
