Hi guys,

I am reading that most of the Fbody guys require the green or metal shim to get good engagement point using the stock master cylinder. I have also read some posts that the Corvette does not require the shim whereas the fbody does?

I am using a new fresh flywheel and new updated master/slave cylinders with drill mods done. This is for a Spec 4 clutch

Does anyone have any advice for me here about the shim, I do not have the shim to install and may have to put off my clutch re-and-re planned for the weekend in order to get one.

Thanks!

I had the local Chevy dealer install my spec and they did not use the shims. Consequently, I had to get a McLeod adjustable master cylinder. I would suggest using them.

From what I heard, you use the shims on FBody's, but not on C5. :cheers:

that's what I've heard as well, but am also hearing that *some* vette owners needed the shim to get the correct pedal adjustment...

more input please! :)

Correct. The shim is for F bodies only. Discard it for a Corvette.

I just did a Spec 2/3 last month. No shim. No problem. Engagement is just above dead center on the pedal, exactly where it was on the OEM clutch.
