clutch recommendations for 540 at the tire

[rkreigh]

I've been scoping out some options for a clutch upgrade.


currently I'm using the stock unsprung disk and a fidanza flywheel. works ok but I'm asking a bit too much from the stocker


I'd love to go dual disk, but not liking feedback on the issue.


has the ram 9.5 gotten sorted out?


Also looking at the carolina clutch stage II, but that too seem to be "at the limit" as it's designed for 525 and not as streetable.


lots of folks like the centerforce stuff too but I'm not sure they make anything that will take the torq in this range.


thoughts? experiences? recommendations?

Ron,
I'm selling the RAM 9.5" Dual Disc 3:1 over the RAM single disc. I "tune" every RAM clutch kit we sell to make it a "plug & play" install. No measuring, just follow our own directions (with lots of photos).

Eliminates;
stock clutch slave cylinder,
clutch fork,
fork ball stud, &
the "unobtanium" OE release bearing.

The RAM hydraulic release bearing is rebuildable, both the bearing & a simple o-ring kit to rebuild.

The organic discs version is rated at 750 ft/lbs torque, metallic discs up the rating to around 950Hp.

Smooth, light pedal.

The organic Dual Disc should be good for most applications and they drive really nice have been working great in my Z and 3 other big motor Z's.

What’s the difference between the metallic and the organic?

Thanks! I think the organic would be plenty and I drove Bob Gs car briefly and was very impressed with the "street manners"


I think this will be the best solution

Dennis, apart from the obvious, material compound and friction coefficient being higher with metallic, the difference reduces down to smoothness of engagement.

Organic is engages smoother as the clutch is released whereas the metallic grabs quicker and tends to jerk during a normal, slow release such as is the typical for street driving. Metallic is better suited for racing, with quick pedal release. Metallic locks up quicker.

For a street driven car, organic is the way to go.
