Spec indicates the 3+ should be good to about 600lbs torque.
and after break in should be reasonable for street use.

Think it is what I will end up going with. Anybody running this setup?

RolexNJ

You will have various opinions on this, but I've been there and done that. I personally would never get another Spec (any stage), ever.

what spec clutch did you use Rolex?
Solid puck disc perhaps?

RolexNJ

I don't recall the exact Spec 3 I had for it's been so long, but the traits the clutch had were, for me, were horrible for a street car. I am sure if you did a search you would find tons of info on it. The TQ rating is excellent, probably more than enough for your car, you just need to determine via research if you can deal with the characteristics that Specs can have. Some people like them very much, but not me, I wouldn't ever buy another one for street applications.

What do you think of Centerforce clutches?

I think of them the same I think of Specs, both have a ****ty pedal feel. Its like sticking your foot in half melted butter or something. Both are very switch like in their pedal feel, a different force at the top than at the bottom. Drive a car with a Spec to see if you like that feel, I personally cant stand it.

You da man Brian....

What type of clutch do you guys like in that case, KEP or just stick with something more factory like a 930 clutch disc?

theedge

I like my KEP stage 2, disc will depend on your power levels. 930 and 951 Cup discs are pretty tried and true, but some people like puck discs.

asking a bout a specific SPEC clutch - the 3+

Giving a general statement without any details on what clutch is not helpful.
For example - Expecting a solid center puck disc to be anything but notchy ON/OFF engagement is absurd. These function as designed and intended
Chatter, and instant engagement are just fine for a race car

What SPEC clutch have you driven edge? how much driving? was it a new install or broken in?

Here is a thread you may find interesting.

Im not talking about the disc, im talking about the pedal feel. Ive driven an S2 with a Centerforce (not sure on the disc, but it wasnt a puck). I personally didnt like the pedal feel. Ive also driven a few Toyota MR2 Turbos with Spec Stage 3s, one with the puck disc and one with a non puck. Pedal feel still sucked. Im personally not too fond of puck discs either, but they do have their uses. Its the Spec/Centerforce pedal feel that irks me everytime ive driven it a car with one of those.

I prefer the KEP because its feel is stockish, you have a smooth continuous force from the top to the bottom. Way better and easier to drive with, but again thats my opinion. Some people like Specs, some dont. I fall into the dont catagory.

Edit: All were broken in with several thousand kms on them.

Thanks Rolex - search had not turned up that thread
leaning against the KEP setup - fork loads are increased -> fatigue/breakage
That ends race weekends - If the trade off is a bit of chatter then so be it.

from other thread -
Kep= high pedal effort, but easy modulation (progressive)
Spec= lower pedal effort, but on/off (difficult) modulation

My car is far from a daily driver, but sees plenty of street driving. I don't expect or require a silky smooth clutch, just one that drives reasonable on the street and will live through the track use it will be subject.

I would love the opportunity to drive a 3+ before I buy one...... anybody got one I can drive?

Thanks edge - that is good feedback

Ive found my KEP stg 2 lighter than stock, because my stock fork and needle bearings were all buggered up and increased pedal effort, so you might be surprised on that front depending on how old your current clutch is. Markus at Blazack Precision rebuilds the stock forks to make them stronger with some welding, and adds sintered bushings to get rid of the crappy needle bearings. Its $120 and worth it, just looking at the fork.

2bridges

yes current slippping clutch is as new "cup" new everything, bearings,pin, etc. when installed a few thousand miles ago. Not hung up bin/fork bearings in this case

still may look into the fork though
