What's gingering the clutch? I have to say, I am pretty proud of my shifts which are smooth as silk except when I am giving it heaps (I find it hard to get the clutch point right when I am giving it stick, but probs because it is very rarely that I do). I reckon in normal driving the shifts are smoother than an auto. But hitting it hard, pretty lumpy I'm afraid.
Before it came to mean “extremely cautiously” in 1600, gingerly meant “elegantly, daintily.” In fact, it stems from the Latin word gentius, meaning “(well)-born.” But today it has less to do with elegance and more to do with a delicate touch, usually used to avoid hurting something.

Can relate to the satisfaction of a seamless shift :clap: . I was just thinking that if you're riding the clutch in any way eg not releasing it quickly at high rpm and flaring the revs before take up, due to the weird clutch feel on our cars, the material can glaze but it seems you're banging them in so that's probably not the answer.

What’s the fix for a glazed clutch? Could it fix this?

A few high rpm launches can sometimes remove mild glazing.

Hmmm I'm not a clutch 'expert' and without knowing driving habits that looks a bit burnt to me rather than glazed but the pattern is interesting, like uneven pressure. Do you have pics of the clutch?

Yes, here are the clutch discs.

That doesn't look bad at all, it's a bit hard to tell from the photo but noting the marks on the flywheel can you see corresponding marks on the disc? Has the flywheel been confirmed as flat and true? Also there looks to be some burnishing of the pressure plate at 3 o'clock. What symptoms were you getting?

Had me going there, too. I was envisioning a guy with red hair at the wheel.

I guess if If you guys were around in the 1500s you'd have known too :giggle:

I didn’t see any corresponding marks on the disc, nor did I check to confirm that the flywheel was flat and true.

I experiened some slip on my 5th pass at the drag strip, as well as crunching on the 2-3 shift. I drove the car on the street a bit afterward and noticed a chirping noise every time I released the clutch pedal during takeoff.

I wasn’t too upset about it, because I had always felt that the clutch and tranny were weak link in the drivetrain and either one or both would eventually give out on me with repeated nitrous use, so I decided to upgrade both. I’ve since replaced the clutch with a Ram Pro Street Twin Disc and lightened aluminum flywheel. I also rebuilt my tranny with stronger internals and special treatments where applicable. I should have the car back on the road soon to begin testing and evaluating the upgrades.
