ls7 clutch shim
i'm having one installed and was wondering if any of you have used a shim? do i absolutely need to shim the slave or is it not needed?
mechanic said there is about a 1/2 inch difference in total height of the clutch/flywheel compared to stock.
i'm also having a new slave and master put in

The LS7 should be the same height as the stock clutch.
There is no shim needed. If you put one in, it will make the clutch pedal grab high. It will release right at the top of the travel, which you don't want.
When you first drive the car, the clutch will grab right at the bottom of the travel. This is normal, since the LS7 uses a self-adjusting pressure plate. As you drive and put miles on it, the pedal will gradually rise to the center point of the travel where it is supposed to be,

alright sounds good.
I'm gonna have to ask the mechanic to measure the height again since it should be the same.
we talked about shimming the slave, but I keep reading that it isn't necessary so I'll probably have him go ahead and put everything together.
What happens if he measures again and there is still a height difference? i.e. the assembly is shorter/longer going towards the transmission than stock

I've never even once bothered to look. I've installed many of them and never had any issues except for the occasional need to bleed the clutch. Everyone has been like stated above just put it in and go.
