Aftermarket gears?

OK , I get it , my clutch is "junk" , but it was fine for 22 years previously of power shifting , racing etc. The only other factor was I had 2 heavy passengers when I smoked 3rd gear. 500 lbs extra will do that. . I'll be fine , if not , then I'll deal with it. The car made MANY passes down the rack with slicks and did just fine with that exact clutch set up.

Yup, I understand. It’s the cumulative effect of all those shifts. I forget, are you using a 3 paddle or a 6 paddle disc?

If it’s 3 you can order a 6 and that will calm it down a bit.

Also you can drop the plate load way down. I forgot where I started getting into issues but I think I could run the 6 paddle down to 1500 pounds and the 3 paddle down to 1000 pounds.

Any lighter than that and it would make enough heat to blow the friction material right off of the disc.

That would help a bunch.

The other thing about third gear is it turns the fastest on the main shaft. So not only are we dealing with the smallest gear on the shaft, plus it’s on the end of the shaft and it’s turning pretty close to crank rpm.

It’s multiple issues. Anything you can do to take hit away from the clutch will help.

An aluminum flywheel is a big deal too. All that rotational inertia breaks parts too. Or helps break them.

I had a guy tell me that when the clutch is right in these cars shifting into 4th gear should feel like flushing a toilet.

He wasn’t wrong.
