Burnt Clutch
#31
Beebo, There can be a number of differences in a stock and high-performance clutch. Unfortunately without knowing what you are actually being quoted for it is hard to say for sure what those differences are. That being said I am happy to provide some general info relative to the improvements associated with aftermarket clutch applications.
The most common changes, when moving to an aftermarket assembly, will be relative to increased clamp-load (which is acheived through the modification of the clutches fulcrum/pivot) and improved friction coeffecient (which is acheived by using a more aggressive disc material). Ultimately the benefit is that the clutch will have a higher torque capacity because of these changes.
Though an aftermarket clutch may have a greater capacity and thus greater resistence to slip under increased power, clutch life is not inherently any better than an OE clutch. Clutch life is ultimately dependent on a number of factors. These include but are not limited to: flatness of the corresponding surfaces (when you install a new clutch kit you want to insure that the flywheel is flat), break-in thoroughness, driving style, disc material used, intended use, and overall torque produced by the vehicle. I will be happy to provide more specifics about these factors if needed.
You can see from the list provided above that flywheel flatness is significant. I strongly suggest that you replace the stock flywheel. Our cars utilize a dual-mass flywheel that cannot be easily resurfaced. Thus, I suggest that you buy a new flywheel. There are a number of options available...ranging from another new stock DM unit to Steel and Aluminum aftermarket options. Remember the lighter the flywheel the greater the potential for increased gear noise, also known as clatter or gear-lash, which is most commonly discribed as a rattle and most evident in neutral with the clutch pedal released and during deceleration. You can use a more viscous gear old to assist in dampening this noise but even this will not eliminate it entirely.
I hope this information helps. I have provided these specifics because I think it is important for you to understand the options available and the pro's and con's of each possibility. Please let me know if you have any further questions. Thanks!

Beebo, that price is way to high you can get a good clutch/flywheel combo from one of our vendors for under 1000$ shipped I paid for my JWT around $700 clutch, flywheel, ss clutch line, upgrade pivot ball, new throw out bearing, and pilot bushing. I did the install myself, but would not pay more than $400 on the install. You should be looking at 1500 max installed with flywheel and everything.

Beebo my clutch went at 20k LOL! but that's cause i slapped a turbo on my car and went to town on the stock clutch. I went with the RPS 6 puck and light weight flywheel which cost me under a grand. Its a amazing clutch and it allows you to replace individual parts instead of having to go get a whole new clutch every time (not sure if other do, probably do but w.e). Also, RPS is a small company so if you call them you talk to the owners themselves a nice selling point to me because, i hate talking to some middle man who doesn't know what he is talking about.
And you can save money by doing the Clutch your self Its not hard just takes two people to put it back in really.

I just had a Z1 Stree Performance Clutch and 13.75lb flywheel installed and I am verry impressed. 759 shipped. Labor should cost you no more than 400 at any tranny shop.
