I'm going to be needing a new clutch soon, mine is starting to slip after driving for 10 mins. I want a good clutch for auto-x since I'll be starting next year. But I also need it to be decent for street driving. How long would a new stock pressure plate last with a 4 or 6 puck clutch disk?

 

I dont know an answer to your question, but isnt a 4 or 6 puck clutch a little much for the street??
I have the Boenze street/strip clutch and pressure plate from www.rx7.com. It is absolutly awsome for the street and rocks on the auto-x course....

 

I have had a Stock clutch for 18 months now, and i do the occasional track sessions.

Clutch life depends totally on driver abilities, the clutch should only be used for 2 things, starting off, and disengaging drive for a few seconds to make a gear change. not slipping to make driving smoother. i have seen friends destroy stock clutches in 6 months, and mine has been going strong for 18 Months already! and i drive just as much if not harder than they do.

 

I was looking at the bonez one, but it's a little expensive. I was probably going to get it from www.mazdatrix.com Sometime I'll have to check to see if I need to replace it all, or if it's just the pressure plate or disk.

 

I really don't want to say how long mine has lasted, because it will be sure to break in the next week, but what the hell. It has already lasted 56 xxx miles, 38K of that by me. And I'm no Sunday driver. I slip the clutch very little, I can't stand people that rev a car to 2k and slowly slide into gear, makes me want to slap them. I have also been rev matching for the last year or so, I would suspect that religiously performing this would extend clutch life by quite alot. The clutch has taken hundreds of 3K launches and un-countable hi RPM shift. Performance has been outstanding so far, it still barks into 3rd gear and shows no sign of slipping. Judging from the receipts it's all stock. I love it.

 

Are you talking about changing gears or just starting out? Maybe its just me, but I have a Centerforce Stage 1, and I have to slip it like that to get anywhere near a smooth take off. I mean, peoples driving techniques vary, but Im just wondering what you meant precisely. I mean, its my money and my clutch so I can burn it up the way I drive and Ill have no one to blame but me, I was just wondering how you do it. So lets try and avoid the whole "youre driving your car wrong" argument, ok?

EDI: I forgot to mention, if you were talking about changing gears after moving, I am with you 110%. I hate when people rev the car up too much and then let the clutch bring it down. Like when you upshift when you shouldnt have on a hill, ya know? That just pisses me off. But like I said, its their driving techniqe, so they can do what they want . I just try and match the RPMs so that The shifts are smooth, but without dragging the clutch too much, ya know? Hell, I got lost writting that...I hope it makes sense.

 

I think I might have the original clutch on my 82 GSL and yeah...it sucks...lol I need a new one.

 

clutch life is 90% driver. the most i have ever seen a clutch go was an 85 gsl-se that wasnt beat on, it want over 250k, really tired but it made it.

RMD: I'm talking about from a standing start. I'm also thinking about one of my freinds in particular, the car gets rev'd to 2k then slowly let out for 3-5 seconds and sometimes the revs start sliding down but bounce back up again because he's putting even more gas into it. This is all on a stock clutch. He also does the slide between gears often too, all the while claiming to be really good at driving standard. Sometimes with a stiffer clutch I'll bring it out in two quick motions, the first a tiny shock to get the car in motion then the second all the way out. This way I can take off smothly from 1100-1200 RPM, kinda like an AWD drag launch.

This is why I love my long "throw" clutch, it allows me to easily regulate it and make small changes. I'd image that a more agressive engaging clutched paired with a line clutch would drive me nuts. Are all first gen clutches hydraulic?

 

your friends clutch wont last very long that way

Thats exactly what I have to do basically with my Centerforce.
