Default Which one? Clutch +375wtq Full Face for 5 speed, dual duty DD + drag

Looking for a streetable/DD clutch that will withstand several passes at the drag strip (25-50) per year torque requirement at the wheels: +375wtq.

This is for a 5 speed trans, I would prefer a full face clutch, not interested on Exedy Stage 2 3-puck.

Any others besides these I should consider with similar specs?

Competition Clutch Stage 2 Endurance sounds too good to be true, 450wtq for a full faced clutch! and less than $700 including flywheel! What gives??

Competition Clutch Stage 2 - Street Series 2100 Clutch Kit Including 4140 Forged Steel FW - 450wtq.

South Bend Stage 3 Endurance - approx 360wtq using 22% loss (advertised as 450tq @ crank).

I went from an Exedy stage 1 HD, which was a very heavy peddle that lasted 10k to a clutchmasters fx350. I have 2000k on the fx350 now and I like it so much more than the old exedy. It feels like stock, easy engagement, very streetable and I plan on hitting up the track lots with it.
Might be an option for you.

Thx, I am actually running an Exedy Stage 1, it is slipping now, lasted less than 20K miles, partially due to driving on 2nd gear, lost 1st at the drag 5K miles ago, and as you say pedal feel is heavy.

Clutchmasters sounds like good option:

http://clutchmasters.com/shop/?page=...21cd0ac1400b64

FX400: Race/Street Ceramic (170% over stock holding capacity)


###-##-HDC4 (Four Puck Disc)
###-##-HDC6 (Six Puck Disc, shown in photo below)
###-##-HDCL (Eight Puck Disc)

The FX400 System uses the Power Plus I Pressure Plate with a custom, extremely durable, Sprung Ceramic disc. This is the ultimate extreme duty street and/or road/drag racing system. It is available in a 4,6 or 8 wing (paddle) configuration, with the 4-wing being the more aggressive setup and 8-wing being the less aggressive (please specify which type you prefer). The sprung hub design allows for moderate dampening in high-torque applications, rendering it much more street friendly than solid or rigid designs. This disc is designed for outstanding holding capacity, and rapid heat dissipation. The FX400 ceramic paddle design creates a quick and rapid engagement as well as clutch chatter that may not be ideal for street driven vehicles. #

Warning: Due to the solid (no Marcel) friction rivet design, the FX400 disc engages very quickly and may chatter slightly in first and reverse. To help alleviate this problem, we only use premium ceramic friction material.

FX350: Street/Race Fiber (110% holding capacity)


The FX350 System uses the Power Plus I Pressure Plate with Clutch Masters New Formula Button disc. This clutch is designed for the street enthusiast or weekend racer who plans to abuse their vehicle on an occasional basis and have a spirited driving style. The FX350 clutch system has a higher holding capacity than a segmented Kevlar lining without compromising the street friendly characteristic Clutch Masters is known for. For year’s enthusiast have had to compromise durability for drivability and vise versa, however with Clutch Masters New Formula button we have closed the gap between these two tradeoffs. *

I'd do the ACT full face with the heavy pressure plate option.

I've just been impressed with the quality of their products. You see very few complaints. The heavier pressure plate holds more tq without going to a non-streetable disc like some manufacturers do, as long as you have the leg strength to push it in. Puck clutches and especially unsprung puck clutches suck to drive on the street.

I've installed a few ACT and taken a few out while doing other work years later and they still look and drive great.

You have too much tq for my preferred street clutch the exedy stage 1.

Problem with this one is the torque capacity, is rated at only 420ft/lb (327wtq).

The Spec Stage 3+ is a good option for full face disc with high clamping power and high torque capacity. Spec rates it at 520 lb ft for the WRX. We've had customers say this clutch is very manageable to drive for the performance. We'll be putting it on one of our project cars soon too.

Here's a good picture of the disc.

good option at 406wtq, shame it requires a $350+ FW.

A simple organic disk will handle a wide variety of use - including street use, auto-x, and even true racing. In fact, SCCA ITS racing rules require a standard OE-spec organic disk. UUC has tested organic disks to reliably handle up to 475hp in long-term street use. M3s regularly run through several auto-x seasons without problems.

A kevlar disk is a good choice for a heavily-tracked or road-raced cars, especially with forced induction.

Carbon/ceramic should be left to high-power cars that see lots of drag racing, or are dedicated track/drag cars.

Sintered iron clutch disks are strictly for endurance racing.

Wrong one. You'd want the one with the XT pressure plate which is rated to 505.

Are people replacing flywheels too with these high torque clutches? I would prefer to reuse the OEM, although it has 100K miles,

^good info, however you have a 6 speed, this is for a 5 speed so I may not be able to reuse it, I will call them up to make sure.

Last time I replaced the clutch it was $10 to resurface the OEM FW at Oreilly's !!

Ended up with the competition clutch & flywheel kit stage 2, Oakos had them in stock, South Bend was highly recommended by Andrewtech but not in stock.

Can you use a resurfaced flywheel with new clutch? Newb question but I'm in like the exact same situation as OP. About 360wtq and need new clutch. I'm gonna go southbend daily stage 3. 95% daily driver and maybe one or two races (at the Hallett race track, Oklahoma).
Think it'll hold fine for me?

Also, don't really wanna go overboard on it since I'm on the 5 speed still. I was hoping the stage 3 daily would be a happy medium...enough for longevity and be able to hold the power, but not too hard on tranny. Thanks guys.

1000 miles so far so good, stock feel. Lower pedal effort than Stage 1 Exedy which is a good thing!!! Clutch and flywheel are top notch quality, fit and finish.

Does have anyone advice on why a fx300 does not disengage? My car won't go into gear with using the clutch, it has to be already in first then throttle control to 2 and so on. There is no smell of burning or slipping, Just hard chatter. I have an ACT street lite flywheel. 22,874 miles on the clutch. Currently checking the hydraulic pressure.

I'd look into south bend clutches. I have a stage 3 daily in my legacy gt and I love it. Feels like stock yet holds the power.
