Has any one done this mod to there car? I am haveing some high rpm shifting problems. I have a new spec 3 w/ slp billet steel flywheel and a new GM slave. I ordered a RAM adjustable master and I want to do the drill mod to. Has any one got some info on this mod or a link that I can go to find out how to do this mod? what do you guys think of the drill mod?

 

i beleive this site goes through the steps

my understanding is the drill mod helps eliminate the clutch pedal from sticking to the floor when shifting hard. that's it.

if you car doesn't do that (mine doesn't) than the drill mod is not gonna do much

 

why is it so hard to shift at high rpm's? every thing is new except for the master cylinder, I have an adjustable one on order.
