I'm asking this question for my brother. He has a 99 Z28 and has all the boltons plus cam, subframe connectors and will probably add more traction mods. I forget the dyno numbers of his car but it is making very good torque and hp I'm guessing around a low 12 second car he hasn't gotten to run it yet. The stock clutch isn't holding up to the power and the car needs something that grabs better. This isn't a daily driver but he would like it to stay streetable. What do you guys recommend. He was looking at the Spec Stage 3. Is that a good clutch, is there any chatter, and how long can you expect one to last?

THe SPEC 3 clutches hold up fairly well and that's what most LS1 Guys I know run. They're strong and seem to last a while as wellRhode Island Red *Lurker since 1997*

Everyone I know of seems to be running the Spec Stage III. They say it takes a bit of getting used to for street driving because it's pretty much an on/off clutch in comparison to the stock, but no one has said it's not streetable. Everone I know with a Stage IV says to not get a IV unless yer building a drag only car.

The Textralia clutch seems to be the hot ticket right now. I've driven a SS with one in it and it holds great but has a stock-like engagement.
They are $$$ though.

Wow you weren't kidding about it costing a bit more. What makes them cost that much more?Originally posted by fastTAThe Textralia clutch seems to be the hot ticket right now. I've driven a SS with one in it and it holds great but has a stock-like engagement.

Man, I gotta disagree. I have driven several LS1's with a SPEC stage III and they engage MUCH like stock. The ones I drove had no chatter and they definitely were not a off/on engagement. Most of the guys that post about the stage IV's even say they are very streetable. Plenty enough for a daily driver.Originally posted by OuijaComment

Spec clutches are not highly regarded in my area - several club members have had them and have had many problems - from premature wear to "blowing up". Obviously this could be caused by a large number of things (ie installed incorrectly). Most of the guys in my club are huge fans of Cartek or Textralia - both a little more expensive.Silver 02 WS-6, 6 speed, Corsa cat-back, SLP lid, K&N filter, BMR STB, !CAGs, Lou's short stick, MSD wires, MTI "Hammer" cam, ASP underdrive pulley, Hooker LTs, Hooker ORY, Comp 918s, TR pushrods, UMI Sfcs, UMI LCAs, NGK TR55s, Hotchkis springs

Well, I don't think it's a good idea to make a lifetime "set in concrete decision" based upon a single experience with a company. NOBOBDY is perfect and should not be judged as such. SPEC indeed had some production/material issues with their disk materials, but they have long been resolved with the x-pad. SPEC makes a great clutch. The Textralia just happens to be a little more street refined.

I respectfully disagree. Screw me once shame on you. Screw me twice shame on me. It cost me about $500 to fix their screw up. I might not have needed a flywheel ($400) but everyone said it was the flywheel because I had it Blanchard ground. Turns out it was the clutch disc. There goes another $100 for a new one because I can't wait to send mine back, have them inspect it and send me a new one which is Specs return policy. It's a daily driver and they wouldn't send me another one while they inspected the bad one. I understand them wanting to do that but if it's a daily driver you can't. Koni knows this so they sent me a new shock They took my credit card number to send me a new one and gave me a month to ship the bad one back. They never charge me. I didn't loose the use of my car like I would have with Spec's method. I don't like the way Spec did business so I will take mine elsewhere.Originally posted by fastTAWell, I don't think it's a good idea to make a lifetime "set in concrete decision" based upon a single experience with a company.

Don't get me wrong, I hear ya.Originally posted by Jeff 95 Z28
I know it sucks to experience "not so good" customer service, but I have just found in life that it's not wise to form an opinion of an entire operation based upon 1 or 2 peoples inability to provide great service to the customer. Many of these larger companies do not incorporate micro-management. This makes it more difficult to keep every single employee under the microscope... you know.
I guess all I'm saying is I've heard more good than bad regarding SPEC products and service.
