I'm a new member of Corvette Forum. A friend says I can get a lot of valuable info here. I recently got a '92 with the standard engine and a 6sp tranny. The clutch is starting to slip and am curious about suggestions for a replacement set-up. This is the 8th Vette owned over a 44 year driving span but all have been pre-1982. These newer ones just blow my socks off but I'm completely stupid when it comes to all the new technology that comes with the new generation "computer" cars. Got any suggestions?? or will a standard aftermarket/any brand work just as well and please share your reasoning, not just that it's a great clutch. Thanks...........

 

Welcome from INDY

Stock clutch package is fine for stock or stock + some HP.

How many miles on the car, might need a Flywheel too,, = pricey .

Also, VALEO makes all the Pressure Plates so there is no new technology there.

 

All the pressure plates and throwout bearings are the same foreign crap no matter where you get them or what box they come in. For the clutch discs there's a few choices.

Get the clutch set at whatever place can give you the best warranty.

Before you leave the store, inspect the throwout bearing closely for cracks in the inner part of the flange. If this thin flange breaks, you will be stranded.



The flywheel is a whole nother story that I don't have the answer to.

 

What are your plans for the car? If you plan to keep it mildly modified or even completely stock, the stock clutch will probably be your best bet.

The clutch in your 93 is a bit different than most clutches you've probably seen. The clutch fork pulls the throw out bearing away from the crank, which disengages the clutch. It's basically backwards from most clutch set ups.

Also, there are no conventional springs. The flywheel is made from 2 pieces of metal bonded together with something like a stiff rubber material. That's why they call the stock fly wheel a 'dual mass' flywheel, because it is made of two different materials. The flex in that rubber material is what gives the stock clutch it's dampening action, there are no springs in the pressure plate or disk.

Your stock flywheel, due to it's dual mass nature, can not be turned down. If there are lots of miles on the car, or the clutch has been abused, your stock flywheel will most likely need to be replaced. They are expensive ($600 or more) and are also very heavy, more than 40 lbs. However, if you want the car to act stock, there is no other option. The stock components should reliably handle just about anything less than 350 rear wheel horse power as long as you don't aggressively abuse the car at the drag strip, or put some sticky tires on it.

If you do decide to go with an after market clutch, there are lots of options. The biggest advantage is the cost of the flywheel, regressing back to a single mass style flywheel is not only cheaper, it's possible to shed 30 lbs. or so of rotating mass. However, the stock transmission is pretty noisy and the heavy dual mass flywheel really helps quiet it down. Going to a lighter flywheel will make the noise more noticeable, but most seem to be able to live with it.

I have a McLeod twin disk clutch in my car. It's pretty identical to the stocker as far as feel and driveability, but it hits insanely hard at the track. Hard enough to break rear end components almost at will. It's an awesome clutch if you plan to make some serious power, but for most people it's probably a bit much.

There are lots of options depending on how much power and what kind of driving you plan to do. Let is know what your goals for the car are, and we should be able to point you in the right direction.

 

Hey Charley,

Glad to see you finally got on..., It Took You Long Enough..

Anyways, you'll find that there are some really good vetters on here,

Please read up on how the dual mass is actually constructed before perpetuating this myth.

 

A search for "dual mass construction" yielded no results. A search for dual mass gave me 159 results, none of which had thread titles that dealt with the construction of the dual mass. If you could help me out with some search terms, a link, or maybe provide the correct information if you have it, that would be great.

I don't really remember what my dual mass looked like when I pulled it out, other than it looked like a normal LT1 T56 flywheel for the most part. I didn't inspect very carefully, didn't look for any kind of specific material, and might not remember even if I did.

My apologies for providing any wrong or misleading information.

 

NP, that tale has been told since this forum began. I found a thread in 2001 where Hib Halverson posted about it having springs and stops and someone came in and told him he was an idiot. Here's a cutaway: http://www.luk.de/content.luk.de/en/...zms_lv_new.jsp

 

my .02...if you looking to replace fly wheel you may want to avoid the aluminum ones. i just replaced my clutch because of the throwout bearing coming apart and threw an aluminum one in...it a race car so all the warnings ment nothing to me...but it is loud!!!
