thanks

 

They don't sell the street strip 215mm pressure plate anymore. It feels very nice in my S model. I bet the race pressure plate will feel quite a bit stiffer but having never driven one, I just don't know.

The 4 puck will suck on the street, unless you have a stock flywheel. It just may be driveable with the extra rotating weight. You won't know until you try. I would prefer the 215mm HD disc because it is a perfect go-between compared to a stock disc (With the springy marcells between friction surfaces making clutch engagement slow and easy) and the 4 puck (which grabs like right now). I prefer the HD disc but you still need to pay attention while driving. Bumper to bumper won't wear you out, although the increased pedal effort of the race pressure plate might...

I assume you're getting 215mm components because you have a stock flywheel. Must you use the stock flywheel? If I were you, I'd get a '79-'82 rear counterweight, light steel flywheel, 225mm HD disc and 225mm street strip pressure plate along with the longer bolt set with aluminum spacers. You can call up Mazdatrix and ask them to put a package together for you in order to place 225mm components where there were originally 215mm components. They state they do this all the time and it's not a problem, or something like that. It's just not listed in their light steel flywheel packages which inclide the rear counterweight and bolt set (it's an attempt to not confuse people but it's no problem if you know which parts you need for the rotating assembly and which parts you want).

 

I agree with Jeff about the HD disc. I got mine from RB and used it with the stock flywheel and pressure plate and I loved it. It grabbed hard when you wanted it to but it was very streetable. I was chirpin 3rd gear in my FB on a stock motor with that clutch

 

+1. I got a 4 puck racing clutch on my street driven daily driver. It's not bad. Just takes a few days to get used to.

 

double post

 

mazdatrix, i had the street/strip disc for a short time, excellent clutch, now kentetsu has it, he likes it. now i have an ebay 6 puck, and it bites like a ****. but i get a ton of chatter if i try and take off from less than 2k rpm.. i dont mind it, but some might...food for thought

 

I have the centerforce dual friction grips great but doesn't chatter like a true puck disc. You get the best of both worlds

 

I had an ACT street/strip pressure plate with an Exedy disc. I was awesome very nice on the street, though I never got around to taking it out to the track

 

if you stil have your old pressure plate, send it to me and I can ask my friend to match it. OR you can bring it to your local shop. They just need to put that P/P in a press to find the #'s or amount of tension. The street/strip are usually below 2500 lbs.

And yes, I agree on the puck clutches. Im running stock pressure plates and they are fine for street use. However, stiffer pedal pressure has nothing to do with the disc. Its in the pressure plate. I havent played with puck clutches and single diapram (sp??) pressure plate combo.

 

thats what i have, i believe, as it is a puck clutch disc, but it is extremely light on my foot, even lighter than stock, which leads me to believe it is a weak/simple PP. on any other car this would be bad but seen as how rotaries dont make torque, im not to worried about it.

 

it is not for a stock flywheel its for a 215mm aluminum.
