Clutch recommendations - ZR-1 Net Registry Forums

efnfast · 11-26-2015

So, I replaced my clutch, flywheel, pressure plate and throw out bearing with an aftermarket. Big mistake.
Do I go back to stock?
I've got a Fidanza, which was the start of it all.
So, I'll install the Fidanza, but what to use for pressure plate and throw out.
I liked the idea of the hydraulic release to get away from the fork and ball, but that didn't work out.

I just replaced mine last week with all OEM, why not go that route?

If you're using the Fidanza, go w new throw out and pilot bearings. I use the Camaro LT1 sprung hub disc and stock pressure plate.

I have the Fidanza and stock PP and the Camaro sprung hub disc (Centerforce fm Summit #381039). Love it!

Also, (it's been a while now) I installed longer (custom) bolts that were part of a kit that included the drill bit and tap, as I recall. (Maybe Dom remembers or has the info on the bolts - I (alas) have lost track of the particulars...)

If and when I need a new clutch, I'm going with the RAM dual-disc setup and be done with clutches thereafter! (I'm assuming their clutch will work with the Fidanza, but maybe not.)

Dom, why the LT1 disc? And, is the stock pressure plate still available?

Not Dom, but the reason for the sprung hub is better quieting of the ZF gear rattle when using the single mass, aluminum FW.

My Z has the "500+" package w/ stock cams. The idle was bumped to 850 rpm to assist with noise. Basically, there is none - or at least nothing worth mentioning. (Now Ami's Z is cammed. That is a different story - but like I said...her's is also cammed.)

My Z at idle with the Fidanza/sprung hub disc/stock PP:

Good article on Marc Haibeck's website.

Marc believes the PP is good for 550chp. I have had good reliable experience w my setup which approaches that level of power.
With the Fidanza you'll want ARP bolts that are the correct length. I believe both Marc and Jerry's Gaskets have them.
With judicious tuning, and good trans lubricant the idle rattle is minimized at idle. There is no rattle once clutch is engaged. I just switched to Amsoil Manual Trans fluid since the Castrol is no longer available through BMW centers.
So far I have found the Amsoil to work just fine maybe even a bit better than the Castrol in controlling idle rattle with higher fluid temps. Shifting smoothness hasn't noticeably changed. I have a Hurst short throw.

Paul, just an FYI. I'm about 4 grand (parts and labor) into the Ram stuff. Looks like it will all end up in the trash.

First I've heard of any such issues. In fact, Bob Gillig (together with Pete) worked with Ram, resulting in the kit that Pete, Bob Gillig and Al Dashto are using. I don't know what FW they are using, however.

I believe Jerry"s Gaskets is carrying the kits too. So, something isn't making sense...!
