i have a z06 clutch with about 6000 miles on it, and it still feels strong, just somtimes it feels perfect after ive been driving on the highway, then it goes away and gets a bit more loose, what should i do to keep it at a reasonable height, adj master cyl? or drill mod to the one i have, any opinons appreciated. kind of a noob to m6 stuff like this.

 

That is the way the stock clutch is. Mine did the same thing. I also did the drill mod and it still felt like that. I junked it and got a spec.

 

Drill mod will help clint.

 

hhaah you junked a zo6 clutch for more junk(spec)? haha do the drill mod it will work out well for ya. the zo6 clutch is a great clutch

 

I don't see what the drill mod has to do with it.

 

It help the clutch FULLY engage. It will stop the little annoying grinds that you hear slightly after you put an aftermarket shifter. The only shortfall is when the STOCK clutch starts to slip, it (the clutch)goes fast.

 

i thought you could just use a Z06 master and slave cylinder instead of this drill mod, is that right?

 

I didn't see anything in his question about the grinding on fast shifts or anything, he said his pedal height is changing and feels loose after a while. I know what the drill mod does, still not seeing the connection.
