I actually never felt a slip flooring it in 2nd to 3rd. Maybe I didn't notice it as much as when the car is supposed to be slowing down, but isn't? The massive shuddering in stop and go traffic convinced me the clutch is on the way out.
And you are right...worth the extra cash to make sure anything that goes wrong is covered down the road. And is IS cheaper to pay someone when time is so precious.
PS--Riff...you have 928 posts...another car entirely!

Agree w/ Tom, Riff, Dan, etc.
Matt would have been out over 7k for the second rebuild on his car if he'd supplied his own parts. On that second rebuild, Bob wound up replacing the waterpump and all belts and rollers as well because he didn't like the idea of them taking a shock like that. He ate absolutely all of it and Matt would have been in deep financial trouble without Bob.
If something goes haywire when you're doing it yourself, assuming you can afford to fix the damage you initially caused, the impact on other aspects of the car could have far-reaching consequences as well - just food for thought.
Another option would be to have the shop price his supplier; if he's using an SSF distributor, I doubt it's THAT much more expensive than many of the standard on-line suppliers. If they are buying over the dealership counter then yeah, you're going to get screwed.

Andy,
My original rubber donut clutch committed suicide, and was replaced with the spring clutch on my 84 NA for $1,646.
It cured the "surging" problem. The new clutch makes the car more acceleration responsive. But there was alot more clutch "chatter" from the spring clutch when down-shifting....one of the things I miss about the rubber donut clutch.
Make sure the flywheel is re-surfaced and the rear crankshaft oil seal is replaced when doing doing the clutch change.

Had an OE from Porsche (cost less than an OEM aftermarket SACHS here, go figure) clutch installed in my S2 about a year an a half ago, and that thing runs great. No chatter. Just smooth shifting. YMMV.

Luis...OE, as in rubber donut, or spring center?? I would hate to get a spring center clutch only to have more chatter!
Andrew - Maybe the early vintage of your car matched to a later model clutch caused the chatter you are getting??

I replaced my clutch myself with a Centerforce (www.dualfriction.com) (No affiliation). I love the feel of it. Very responsive. Anyway, I'm also 17 and in high school, but lucky for me the clutch went out first day of summer vacation, so I was w/o a car for the first 3 weeks of summer. I ordered all my parts online (Except TO bearing, got that locally) and did the work myself. Of course I have a lift, and access to a number of cars, so if I messed up and had to park the Porsche for a little while I'd be alright. If you need the guaruntee of the car then take it to a mech and let him order the parts for you.

If the spring centered clutch chatters too much, I believe every 951 owner will be complaining since all 951s use spring center clutches. The "surging" has nothing to do with how much friction material is left. It has everything to do with the broken rubber center causing the center metal sleeve to hit the metal stop on the disc when angular acceleration of the clutch goes from positive to negative or vice versa (going from acceleration to deceleration or vice versa). Do a search and there are probably other threads explaining the absolute stupidity of the rubber donut center clutch. Its the reason why they no longer make the rubber clutch.

I had spring center clutches in my 951's and my 89 S2, and have a low mileage rubber center disk in my S2 Cab. If I was doing the clutch in the Cab and I did not plan on big power mods, I'd do the rubber center again. It's quieter and takes a lot of the harshness out of driving a stick. The rubber center seems to last longer than I'd be likely to keep the car, or at least have the engine in it. It'd be nicer in stop-and-go driving and there is no significant downside that I am aware of except for the rubber failure in the next 15 years.

FYI, my cousin's rubber donut failed in 2 years with 32k on it. The friction material had 85% left. My 90 S2 with spring centered clutch is quieter than my 89 951 I believe due to more insulation material and sound dampening. The S2 has 160k while the 951 has 81k.
