well after a night of runnin my car hard down highways and streets and whole bunch of other people on Deer Park Ave and the 495 my clutch is finally beginning to slip. now heavy throttle has an ACT HD Clutch Kit, Street Disk and an ACT HD Clutch Kit, 6 Puck Disk. which one will work better with a B&M shifter.

and for the record i search but didnt see the combo w/a B&M shifter

AND i need to know of a good flywheel.

Are you running NA or Turbo? If you are NA then go with the ACT HD Clutch Kit 6 Puck Disk. If your turbo I'd think of something else. Go with a fidanza flywheel again if your N/A ...even then a flywheel mod, I guess if your pumping around 200hp it's worth it, if not hold off for a bit and get other mods. Stillen is another flywheel however it is 200 bucks more than a fidanza, weight is the same (11 pounds)

B&M will work great with anything, actually there is not another shifter I think I'd rather use.. some people like the "c's" which i think is no longer being made and was created in japan, pilots suck, obx suck and haven't heard about megans yet, though the setup seems to be pretty close to OBX.

Yea it would work fine. Since I dont' know what you are doing with the car I might even hold back on the Clutch kit, your stock clutch is actually not that bad. I have full bolt-ons and still run with stock clutch and flywheel because i'm not creating enough HP for it to make a real difference. If your going all out N/A going to do cams, pulleys, ecu, springs, valves, port and polish etc then the kit will benefit OR if you go turbo/swap. If you have just bolt-ons I personally wouldn't go with clutch/flywheel just yet, I'd actually start working on my suspension. :)

well i put my stock clutch through hell a few times, and when it gets real hot from clutch kicks or just plain abuse sometimes it starts slipping. all i do is drive normal for about an hour and its back to normal. try it before you go ordering parts.

A good flywheel: The factory flywheel

A slipping clutch: What the hell are you people doing to these cars? If it has over 70K miles on the clutch I can understand, but it seems we get questions about clutches every other day here and they are always the same.

A good replacement clutch: Do not buy a puck-style clutch if it is the first clutch you have ever "upgraded" and especially if you are making stock power (less than 200 at the flywheel). Stick with a street disc, or even better, a good factory replacement. I can guarantee if you buy a puck clutch, your next post will be "my pedal doesn't work right with my clutch". You wouldn't be the first, nor it seems, will you be the last.

B&M shifter: What does this have to do with a good clutch?

the act puck clutch i belive is unsprung, thats what you want to prolyl not get. a pucked clutch is jsut fine as long as its sprung. that makes it very streetable. i have a spec stage 3 6puck sprung right now holding about 300rwhp and its a great daily clutch. its slips when i launch at the track but never else. i am selling it next week to make room for my clutch masters stage 5 unsprung clutch. which should be fun getting used to. if your interesed in my clutch it will hold all your n/a power jsut fine. i also have a brand new disc for it.

the shiftere has nothing to do with the kinda of clutch you get.

a lightweight flywheel is a great upgrade for turbo or non turbo cars.

I have to take issue with you over a puck-type clutch. You obviously know what they are and how they work. You are also obviously experienced and skilled at driving a system like that. Please keep in mind though, that people who ask these questions have never driven a clutch like that, much less chosen one for a specific purpose, or adjusted the pedal to take advantage of the decreased "takeup". Your definition of streetable is "streetable to me", while I try to keep the definition of streetable as "factory replacement". I would then offer them the differences from stock as they go up the list of clutches. Too many people are mislead about the "stocklike" driveability of some of these high-performance clutches. Too often they are too costly and too aggressive for what they really need. The next thing they do is come here to try and get help fixing something they never should have gotten themselves into without doing some research. I am simply hoping to save them some grief.

very true. the only other stock manual car i really knew was my 91 celica i jsut sold. i thought tere wasnt too much of a difference betweent hem. i cant compare it to a stock 240 since i have never driven a stock 5spd 240. i put this clutch in when i did my 5spd swap. i figured with a guy that seems to drive his car fast and hard that more of an upgraded clutch would be better for him

I can see that, but there is also this: Quote »which one will work better with a B&M shifter[/quote] which just screams "haven't yet had a chance to really learn about how a clutch works or what I really need". Perhaps he is starting his educations here! If so, good for him. As long as he tries to learn. :)
