I believe my clutch is on its last leg. After searching multiple threads I think I'm going with the ACT TY4-HDMM street clutch. I am wondering if anyone has tried the F1 Racing Flywheel. It's an ebay flywheel so I am skeptical. Is it fine to use my stock flywheel? Or Would it be best to get my stock flywheel resurfaced, purchase a new stock flywheel, or try this F1? Any suggestions welcome. What combos are people having good luck with?

Is clutchmaster/fidanza what you run? I'm pretty set on an ACT clutch...Is it a must to do a flywheel when upgrading the clutch?

Subscribing, my clutch started slipping and am considering a slight upgrade from stock. Going on air ride soon so nothing crazy just something a bit more fun.

I've been using the F1 Racing Chromoly Steel Flywheel 11lb. for 30,000. No problems at all.
Stay away from F1 Racing's clutches though.

I'm running the Exedy Stage II cerametallic clutch which is a three puck design and a Clutch Masters 12lb aluminum flywheel. I have about 150miles of break in left, but I like it so far.

Are you NA or FI?

The ACT clutches seem to be of good quality so good choice there (I was between ACT Street clutch and the Exedy I'm running). There are a handful of people out there that have problems with after market throw out bearings whom recommend using the OEM TOB when changing clutches. As for flywheels, the very least you should do is resurface the flywheel before you put the new clutch in. I have never used a 9lb flywheel, but from my understanding they are more difficult to launch well; however they're best used for autocross where quick deceleration and acceleration is more advantageous. For FI apps I read that steel flywheels were recommended being that they are a bit more durable, but I'm running an aluminum flywheel and know people who still do regardless.

Hope some of this info helps.

I have a turbonetics kit currently. I was leaning towards a fidanza flywheel...found a place online selling it for 300 where the F1 is 190. I'm glad people are coming out of the woodwork saying the F1 has held up. Tomorrow I think I'll order the ACT TY4-HDMM and the F1 11lb steel flywheel. Thanks for everyone's help. I'm sure I'll have questions when it comes to my install.

go with fidanza
i dont think f1 is good for turbo IMO

car_ram_rod

do you have experience with fidanza HBFMtc?

HBFMtC

but my setup is stage 2 Clutchmaster with Fidanza Flywheel and i love it
best set up IMO

Like what is said above, I have the F1 Racing Stage 2 Clutch and 11.4 lbs F1 Flywheel. I ran them for about 20K now, they are still holding up, but it seems that the stock clutch grabbed a bit more. And the pedal has very soft feel to it, not anywhere close to stock feel. Took a while to adjust and staled many times, lol.

This might be a dumb question but i really dont know and i cant find my answer. Can you use any clutch with any pressure plate? Like would i be able to use a ACT Heavy Duty pressure plate with like a stage 3 F1 or CM or any other clutch?

I've had an F1 Flywheel for 3 years now, about 35K miles, and never had a problem. I'm using an Exedy Stage 1 clutch.... it's kinda mushy, very soft pedal, going to upgrade clutch soon, but the flywheel has been great!

Yeah i want a strong pedal feel so thats why i want to use my ACT Heavy Duty pressure plate with the F1 clutch and F1 11.4 Flywheel. But I want to make sure the pressure plate is going to work. I have seen on ebay Subaru kits with ACT Pressure plates with a F1 clutch.

Does any one have an answer?

Well let me try to debunk some rumors about F1 clutches for Scion's. Some people say "China" others just take a stab at them with ebay clutch. While they may be an Ebay clutch they aren't exactly "China". I work with many clutches in my profession, some hold insane amounts of power and others are for scooters. I test the load on the pressure plates and make sure the rate is within a specification window.

Moving on with the information. F1 clutches for our cars are AISIN HD pressure plates with a disc riveted with copper ceramic pad material. I have only worked with stages 3 and 4. Both were copper ceramic. The Aisin HD pressure plate has a clamp load of around 2200lb. The Release bearing that comes included in the kit is an NSK. The problem with these clutches is really simple to explain. The people using the clutches don't break them in properly or fail to understand the limitations of the actual unit.

Copper ceramic loves to smear like lipstick on a mirror when it heats up. This just makes the slipping condition easier to achieve with these types of clutches. Riding your clutch or unnecessarily dwelling between shifts (long clutch releases or pushing the clutch way past release) causes excessive abuse on all clutch components. These type of conditions will cause early clutch failure. Copper ceramic does handle a good amount of heat but once you burn that baby it will never hold the same.

So... F1 clutches are good if broke-in properly and used within realistic limits. You can use these F1 discs with other pressure plates. You should try and see what type of disc material and pressure plate combination works best for your needs.

I know I didn't cover a lot of what-ifs and clutch designs but I hope this answers what you're asking.
