Fidenza makes a nice aluminum unit. Caroline clutch will fix you up.

Very happy with ours.

Be SURE to use the Bolts the send. Pressure plate bolts are something of a nightmare. Do Not use the originals.

Expect more clatter from the transmission though. That should be expected.

I installed a heavy single mass flywheel from Carolina Clutch and the chatter is almost unbearable. RAM has a dual disc that looks interesting. They claim smooth driveability. The original dual mass flywheel is not available. I am taking mine back apart this winter. I hope I can find a unit that gives smooth drivability. The CC setup leaves much to be desired.

I have pretty good luck with my CC SPEC Stage 2 clutch, but there is some chatter, due to the fact the clutch surface has a higher friction area and is "grabby".........If you go with a RAM just make sure you don't go with a "puck" style 5 finger type disc........you think you have chatter now...............been there and done that!

For the flywheel:

SPEC SC05S-2 (extra mass option).

http://www.lmperformance.com/40428/25.html

For the clutch: (I'm assuming it's for the 1992 listed in your profile)

SPEC SC422Z (Stage 2)

http://www.lmperformance.com/49215/25.html

This set up will drive like stock for the most part, with way more holding power.

very streetable; that is basically what I have only I have the lghtweight aluminum FW.....with higher idle speed it is nice.....no tranny noise and easier take offs from a stop! but with the heavier FW as you mention, it will be better for driveability.......

Going to a Solid flywheel (as opposed to the Dual Mass Flywheel), will pretty much guarantee that you'll get some transmission noise (clatter)when idling in neutral with the clutch engaged (foot off the clutch). Will it be annoying - it depends on your definition of annoying. The OE clutch disc does not have a spring center - this wasn't really needed with the DM flywheel.

Centerforce has a listing for the LT1/LT4, but a couple of years ago I tried to get one, and after a number of months, and a number of calls to Centerforce, they basically said there was some kind of problem with the tooling, and they weren't really planning to go back into production as the tooling was too expensive for the relatively small number of pressure plates they sold. Maybe that's changed - but I don't see the listing in the normal catalogs, so I'd bet it hasn't.

The problem I am having is NOT noise. It is chatter. Feels like I am trying to start out in 3rd gear. The whole car shutters. Reverse going up a slight grade is a real adventure. That is why I am saying it is not fun to drive. Once I am moving, it is no problem. People keep saying the DM flywheel was only needed for noise issues. Other people (CC) tell me it also takes care of chatter. If the latter is not true, the CC clutch product is not a good choice. I want to have fun driving this car, not be uncomfortable at every intersection.

I went with this package, too. I'm pleased. Very little gear rattle -- I can only hear it with the ragtop and windows up. So far, so good. Much cheaper than a DM, too.

Live well,

Any chatter in reverse moving up a slight grade? That is where I ALWAYS have that sever lurching. No matter how I feather the clutch pedal.

I have it with my set up; SPEC stage II, alum. Fidanza FW; but it is a huge improvement over the RAM puck style disc I had prior.....the SPEC II is very tolerable; nothing eratic; will it be like the OE dual mass set up? NO. but very good balance between performance and driveabity; I would replace this unit with another one...the solid heavier one piece FW might be better for chatter than the alum. piece too that I run.
