Which clutch [Merged 3-9] what clutch best

[rayden]

ok i am going to get a new clutch for my car. i was wandering which one i should go with. i was thinking of the act 2100. Dont think i want the 2600 because it is a daily driven car and will only go to the track a couple times a year. if there are some other brands you all would suggest let me know. i want a good streetable clutch for a cheap budget.

They are compatible but I recommend against running the Kevlar surface disks (TZ-Series disk) with them in abusive applications. If it is simply a daily driver and not getting launched regularly then it should be fine. The problem is the different thermal expansion rates of the aluminum flywheel vs. the carbon steel insert friction surface causes problems with the surface warping and resulting in uneven wear on the disk, clutch disengagement issues, and reduced torque capacity from the decreased surface engagement area in contact with the disk.

I have ran the Fidanza with the Kevlar material in the past without problems in a DD, but had to replace the friction surfaces regularly when it saw abuse and track time.

I recommend the Competition Clutch 4140 heat treated chromoly flywheel or the ACT Streetlite flywheel; both choices I keep in stock for all DSM 6/7-bolt AWD and FWD applications. The 1-piece flywheel design with a uniform material is more consistent for thermal expansion and the likelyhood of warping one of these is pretty low. I also prefer to have a 12# flywheel in the car vs. a Fidanza 8# unit which a lot of people without standalone ECU's have decel throttle, neutral stalling and idle stability issues with since they cannot control the idle speed controller stepper motor or they are set up for MAF instead of speed density.

I also offer media blasting of the flywheel friction surface if it is being used with a Kevlar friction material to promote material bedding and reduced break in time. Recovery time to bed the friction material is quicker and reduced surface glazing potential are benefits to this surface treatment.

Well I have had alot of issues with my act flywheel, my pedal is right off the floor and i think it was improperly stepped. And if i recall correctly the guy at the machine shop said it cant be turn again because its been turned about 3 times (in my possession) because i had other shops mess it up. So i ordered a fidanza to go with my act 2600 set up but i really dont want to take the tranny off another time so i might just replace it with a new clutch also. but i dont want to pay another 500 for a 2600. so I as wondering what clutch kits work good with the fidanza. my hp rating is about 350-450

You could go with a Competition Clutch stage 3+ ceramic disk on a 2700# pressure plate with your Fidanza flywheel. I do stock those as well, if you are interested in pricing just PM me and I can give you several choices below $500 to meet your requirements.

What are people running for the 4-500bhp range? My centerforce failed a bit premature, half due to my error, but I figured I might beef up for future. The car is running 299awhp (350-360bhp?) At 18psi and I'm going to add another 6 or 7 psi for a final tune in it once I put a new clutch in.

I'll be completely honest and say I haven't put any time into researching this at all for the 8 months the car has been sitting. I just want to get it back gong, finish with the tune and start enjoying just driving it for a while (no events this summer).

Edit... That's not to say I won't be tracking it anymore, just not for the time being.
