Clutch response?
I've had issues with high rpm shifts and the clutch either not wanting to come up or just loosing it's "spring". I've sucked out and replaced the fluid in the reserve over and over again trying to get as much of the fluid with what I understand the be clutch disc dust in it out. Anyone have any recommendations on what to do to fix it?
Thx

I have an 03 Z06.
My car developed the same symptoms as you described.
I've always kept the fluid clean.
Every day driving, there is never a problem.
Go to the strip and it started exhibiting the same symptoms as you mentioned.
Being it still has the original clutch, p/plate t/out bearing, slave & clutch master cylinder.
I had heard that installing a Tick adjustable M/cylinder may/might
take care of the problem.
Well, I figured I start there before doing a tear down of the other parts.
Low & behold & two years later, no more problems .

Especially if you have aftermarket headers, these two things may offer a noticeable increase in clutch performance (although probably won't cure your problem completely):
- use a high performance fluid in the clutch, like ATE Super Blue, Motul 600, or Castrol SRF
- wrap the clutch line in a thermal barrier where it's nearest to the headers. Two or three layers of this - http://www.firesleeveandtape.com/AB-...g-S-FS-VCL.pdf - followed by an outer layer of this - http://www.firesleeveandtape.com/AB-...-FG-AL-VCL.pdf - will work well.

The first 1/3 of the pedal excursion weighs a ton. The second 2/3 of the pedal excursion feels close to stock. Because of this, the feel of the entire pedal excursion is not uniform. The clutch grips virtually instantaneously in the first 1/3 "heavy zone". In my opinion, this unit is not streetable but great for the track.
In case anyone is wondering, I did contact Tick Performance to see if I could address these issues and they told me this was the way it was. I removed this thing from my car after 5 days and 120 miles.

Here's what I can offer about the Tick Master Cylinder... because I had one:

To the OP and others....You can buy a stock 2004 Z06 clutch master cylinder that fits on all C5's. It is an improvement over the original one.

Yeah, I agree that it grabs a lot faster. Since I put headers/ full bolt ons on my Z06 the clutch pedal has been sticking to the floor, I need to get a Tick M/C bad. I had one in my last car (H/C/I/E car) and it solved the problem.

The tick deff has its down falls... does help high rpm shifts, but it makes even the stock ls6 clutch very difficult to slip/modulate and has uneven pedal feel vs. Pedal travel. I wanna try putting the clutch assist spring back in.. see how that effects the feel. But i am considering removing the tick..

Every thing other than the Tick installed.
I noticed a little (not much) increased pedal pressure. (no problem)
Other then that, every thing else is pretty much the same...
other then no more spongy pedal & pedal not wanting to come back up
after high RPM shifting.
I absolutely love the Tick adjustable clutch M/C.

My 03Z had the pedal to the floor problem. Did the Ranger flushing and still stuck to the floor. replaced the master cylinder 2004 upgrade and still stuck to the floor. Installed a remote bleeder and bled the crap out of it. Still stuck to the floor.
Replaced the clutch with a Monster stage two with lighweight flywheel new slave and insulated the lines.
No more sticking to the floor. Stock clutch was in good condition but was probably slipping at high rpm and overheating the slave. Problem fixed for good I hope.
