performance clutch
Hi guys, I have a 1975 c3 corvette, manual gearbox.
The entire mechanical are original, the problem is last year, I got this sound when I remove my leg from the clutch the clutch start to make noise. I'm 80% sure that I need to change the clutch.!
However, now because I’m changing the clutch, I want to make an upgrade so I want to know what name brand or type of aftermarket performance clutch that I can use with my car "and what not to use "
Now I know that most people will say why you don't keep it original mechanics. Will I’m planning now to upgrade the car, I just got long tube headers for it, and I’m planning to get vortec heads.
, and maybe more
Thanks

I use SPEC clutches and flywheels.
As for your "upgrades". Keep in mind that adding "this and that" bolt on parts ...in the attempt to drastically increase the horsepower and torque...the original internal parts may not be up to the task...and be reliable.

Most do say stock is enough. I choose a Hays based on my experience from years ago but, I'm not impressed I hope it performs better than it looks.In hindsight I would go with SPEC check out the website. I wish I did.

That true, but it won’t be an all day drive, and I’m not planning to use it on track. It will be in the garage
for 80% of it life. I just want it to be like a show car, or a 1 day in the weekend drive. This is what I have in mind for now. For that reason I’m looking for a nice performance clutch

Unless you have major mods to the car a factory style clutch will work fine. i.e. don't over think it.
Check amazon, rockauto, advance, etc... for a full clutch kit. Also a good time to change the trans seals and fluid.

From what I've read, the factory 11" clutches are good to about 425 flywheel torque.
If you're still running 15" street tires, odds are you'll be fine as they'll give before the clutch does. Stickier stuff, go with a beefier clutch.
I just ordered a Centerforce dual friction 11". Tech told me it was good for 580 flywheel torque. My new motor should exceed the capacity of the stock clutch by about 20%, so I proactively stepped up. Unfortunately, the car won't be back on the road for at least a month most likely.

I just installed a RAM HDX kit-semi metallic clutch disc with my new motor on the recommendation of the engine builder who reports he has good luck with them. Best I can tell without the engine running is the feel is about the same as my OEM clutch which was the original with the OEM pressure plate.

Just installed a Dual Friction from Centerforce in my other car--super grip, but a needs a ton of leg--my previous clutch (which I would not recommend because it broke) was a ZOOM HP...great pedal feel, but wore completely out (and the throwout bearing exploded apart) in just a few hundred miles--and no, I don't beat on it. That also, could have been my fault, though, for a bad adjustment...
