Good question. A couple of things come to mind:
1. Too much or or not enough release bearing to clutch finger clearance could lead to premature bearing failure, or
2. Too much or not enough wear adjustment could lead to shortened clutch life.

Or it might be just fine as is. Does anybody know of the dimensional differences (if any) between the LS1 and the LS9 slaves? I think that's what we need to know.

John, I found out some info on the dimensions for the for the LS1 and LS9 slaves. I contacted Katech and they said the ZR1 LS9 slave is 2-3/8” when compressed. I went to an auto parts store and measured an LS1 slave for a 2002 camaro (AC Delco #386433, Summit #24264182) and it was about 2-1/2” when compressed.

It looks like either the LS1 or LS9 slave would work. The plumbing is slightly different on the two slaves, and the ZR1 slave has a rubber boot covering the spring and the LS1 slave did not… I’m not sure what other differences there might be.

Dale,

I was working on the exact same information. I agree that either should work fine, and I am resting easier myself since my project's drivetrain is all bolted up and installed in the car.

Thanks!

Good news! Thanks for the update Dale. Pretty cool that you took the time to find out this info even though your ride is done. Much appreciated.

No problem guys...

Be sure to report back how you like the clutches... I'm sold on the set up. It's hard to beat the OEM stuff. Super smooth engagement and firm grip.

I'm running the same ZR1 clutch in my Z06. I've got about 300 miles on it, and it's great. Smooth, easy on the leg, etc. No hint of chatter or anything like that. I'm a big fan of OEM clutches too.

This week I registered for a track day out at Portland International Raceway at the end of June… can’t wait to get back out on the track with the new engine and transmission.

I made a few other mods to the car recently to get ready. New wider front rims and tires... replaced the Bilstein shocks with Hotchkis Tuned Fox shocks... and I modified the exhaust system with new mufflers and larger diameter tailpipes.


Here is a shot of the new 9" wide rims. The old rims were 8".






I went with Nitto NT01's 255/40/ZR17 which is 10.35 inches wide (about 5/8" wider than what I had before). I added some adjustable stops on the Global West A-arms so I could prevent the inside of the tire from rubbing on the sub frame rail.








I took about 60 LBS off the front off the car with the new engine and increased the footprint of the front tire... this should help to balance out the handling and reduce the push some.

One other thing I want to do is mount a fire extinguisher to the DSE 4 point roll bar on the upright. Not sure what most guys are using... open to ideas.

Dale, I'm using a mount from Scott Drake (bought it from CJ pony parts).
