Who has had it?
Did your clutch ever stick again?
Where did you drill?
Do you have Pictures?

 

It didn't help my car at all. I have a 2000. I finally just got a new clutch, master & slave. See installuniversity.com for pictures and instructions.

 

Yea but who has had good luck with the mod?

 

I screwed up the first time trying to drill it with a 5/32 drill bit rather than a 1/8 thinking that bigger is better and drilled the sleeve to thin causing the inner lining to get cut and it leaked. Went and got a used line and the second time was easy, clutch works awesome "liitle chatter still"

 

should i go ahead and do it? is there need to pull the whole assembly out (master cylinder)?

 

I did this after several track days where it simply would not go into 3rd normally after a low-speed, 2nd gear turn called the Oak Tree at VIR. The turn follows a 100+ mph 4th gear run and opens onto a 4000 ft straight. You really want to come out of it in 2nd, but 3rd was a wall and required coasting a few yards to let the hydraulic fluid "catch up" before it would go in.

So I did the drill mod and it seems to have done the trick. The last 8 or so track days have not seen a repeat. I'll give it a thumbs up.

Ok was this dumb? I have a 98, and "back in the day" my clutch sucked....I believe that GM discontinued it, anyway replaced it with a new GM clutch that was for the Z06 with a new slave / master. The slave master assy. was supposed to have been updated? anyone know if that is true? Or should I just take it apart and check? I noticed Keliente did the mod on a 2000, I thought problem was solved by then???

 

Drill mod works. It will solve many issues with getting from second to third.

 

i got a spec Stage 1 clutch in june of 2005. i broke it in properly i dont beat the living crap out of it. i replaced the slave and release bearing a week ago. i went to the track back in august and after a few runs, it slipped a lil going into 3rd, will the drill mod help this problem? 98 ta with free mods lid magnaflow catback pro 5.0 shifter , 285 40 17 firehawks on the back

 

will i need to pull my whole master cylinder out to do the mod?

 

www.installuniversity.com that should help you my friend

 

Yes you will need to pull the master.

 

The drill mod removes a built in restriction that slows down the flow of the fluid. So by removing the restriction, you are allowing the fluid to flow freely and thus engaging and disengaging your clutch faster. I have felt on mine where the car feels like it is slowly speeding up until the clutch is fully engaged. I plan to make sure to do this when I replace my clutch master (hopefully this winter). I hate that feeling when I am getting on it and can feel the clutch not fully engaged.

 

i can perform this on my stock master cylinder right?

 

yes..

Worked on my 2001,third gear is no longer a problem.

 

awesome im gonna do it sometime this month before i go to track. approx how long does it take? im pretty good with tools and stuff too. i just put a new 6 speed in my car 2 weeks ago. i put the a/c in it myself too and did a bunch of free mods, including my DIY FTRA
