Clutch types
 

I'm about to purchase a new clutch this weekend off of ebay and I was searching ebay and I see that there clutches for 89-91 gxl and gtu and 86-91 convertible. Well I have a 91 na Coupe sooo does it mater if I buy the one that says gxl and gtu or the convertible clutch?

i wouldn't trust an ebay clutch. get an exedy oem or a stage 1 if its a daily driver. so far im pleased with my stage 1 exedy. theyre not too expensive either

Why does everyone look at ebay first before searching google for aftermarket parts? ...... I would go with ACT, centerforce, or like the above posted exedy. While your in there I would think about getting a lightweight flywheel.

To answer your question, all NA clutches are the same. I'd also suggest going with something better than a ebay clutch. There are some decent ones, but it's always going to be risky buying cheap parts that rotate at 7,000+ RPM.

check out racingbeat.com if you want a good clutch and not too expensive

not trying to thread jack, but im in the same boat (just not with ebay, only in getting a new clutch).

whats your opinion on a centerforce I from mazdatrix?

The only differences is thickness of the clutch disc - I think the S5 is thicker.
This is according to Mazda OEM spec, so I think the aftermarket clutch guys sometimes follow this.
The clutch thickness isn't that big a deal, since the clutch pressure plate is self adjusting.
This is why most aftermarket clutches are listed as the same part number for ALL non-turbo FC applications.

As for the Centerforce 1...
It's an OEM replacement.
It's not meant for higher power levels than stock, do if this clutch is going on a stock car, you should be fine.
If you car is modified, there are a lot better options out there than a Centerforce 1.
