I've had the clutch in for roughly 20K-25K miles or so, and as of late, the clutch isn't grabbing right away when I make super quick high RPM shifts in race situations. I'm literraly outshifting the tranny. I upshift it and let off the clutch quickly, but then there's a bit of a lag from when I make the shift and let off the clutch until the car starts accelerating.

Is this a sign that the clutch is done for? I have probably around 40-50 6500-7000rpm clutch dumps at the track, and lots of abusive driving. :burn:

Can I just buy the twin disks and put it in the single disk clutch housing?

I'm told no it can't be rebuilt, and the worst part about it is McLeod doesn't sell the clutch only.

You have to buy the entire package which I already have.

I think my only bet is to go with a stage 3 Spec.

Have you considered a Ram clutch? I have heard they will rebuild them, surface and balance PP and flywheel, for a small fee.

I just bought their VDS system with aluminum flywheel, sintered iron disc and 402 pressure plate. Installing it next week.

I think I found out a way to check for clutch slipage....

I was told that if I change the A/F ratio section on the bottom of my dyno graph to MPH, I can see if the clutch is slipping.

Supposedly the MPH line on the bottom of the dyno graph should be a straight line (at an angle) all the way to the redline. If the line isn't straight and I'm seeing dips/drops in the mph line, it's a good sign of slipage.

Can anyone confirm this?
