You can't beat the pedal feel of the exedy stage 1. When I say the pedal pressure feels like stock, I really mean It literally feels like stock. Even with 345whp(DD) there's no clutch slippage and no heavy-ass pedal pressure that can kill your master/slave cylinder.

That bad really? Kinda concerning since that is what is being installed on my car as I type this. Oh well, I'm up for a learning curve I guess. On the plus side though, if its that light it must rev pretty quick and feel very responsive.

Do you know which ACT flywheel they used (11.8lb or 10.5lb)? Also do you by chance know the Clutchmasters flywheel weight?

The 3 streetlite (11.8lb) setups I have sold with the SS street disc the customers have been very happy with. Just a bit more aggressive than the stock clutch.

I have another guy who has a Clutchmasters FX400 which doesn't stall, but it makes a whole bunch of noise with the clutch in, or when taking off from a stop sometimes.

I am trying to figure out what should be the go-to clutch for this car. I have no brand allegiance's. For the past few years ACT has been on there game, and I had planned on putting either a street or 6 puck sprung ACT in our car when I install the turbo kit.

Please, take my word with a huge grain of salt, as I have not driven it, but just relay information a friend who drives it told me.

I believe it was the 10.5 lb and I believe that is the main culprit. The 11.8 should be noticeably better. Also it was a modified car with LW Pulley too.

I will let you know as soon as I'm driving the clutchmasters how good/bad it performs (FX300).

I was leaning heavily towards Exedy. Three things swayed me towards CM:

1) Reviews for both online were more favorable towards CM (not on our cars, but any car in general).

2) Exedy was not yet available at the time so I would have had to wait a bit.

3) The torque rating was higher for the CM.


I think they are both awesome clutches.

We can tell you with certainty, that it is the closest that you'll get to the stock clutch, in terms of range of modulation and overall feel. There is a little bit of clutch noise when idling in neutral, but it's very minor compared to most other aftermarket clutches. This clutch is 100% parallel parking friendly.

Please contact us, if you'd like any additional information.

Have had good luck with this clutch on WRX/STI, but in this case, the stage 1 for BRZ/FRS is only rated at 203 wheel torque, so I feel like it is only a matter of time before it calls it quits in a turbo application.

Specs:

Disc Size 225mm
Spline Teeth / Major Dia24T / 25.2mm
Clamping Force/Load exerted (lbs)1652
Disc Material Organic
Number of Disc Single
Type (Push/Pull) Push
Sprung Center (D-core) Yes
Clutch Torque 319
Torque Capacity at Wheels 203
Torque Capacity at Flywheel 254
Flywheel Weight FF503

The VividRacing FR-S had one in it way back when...at least they claimed that they did.

So, it seems you were right. It LOOKS like i got the FX350, not the FX300.

EDIT: Box says FX300

Look at the face of the disc I got:



Now look at the face of the FX 350. Look closely at the friction surface, even though its different colors, it is the same shape and size. The small contact areas are completely separated by themselves.




Now look at the FX300 face and see how instead of being completely separated per contact area, there is still a little bit of material on the edges to connect the whole contact area as one.




Reviews to come as soon as I am able to drive it!

I have the ACT 6 puck and lightweight flywheel. I hate it but hopefully I can get a more streetable disc like the FX350 later on. Just need to give manufacturers time to catch up.

Call me crazy but I'm a fan of a weak clutch. Well, not weak, but you don't want it to the the strongest link in the chain, you want it to be a drivetrain fuse. I made that mistake on a wrx and went from having a bit of clutch slip to having two gearboxes grenade at the strip. Clutches are cheaper to replace than gears.

Which flywheel prolite or streetlite and is it a sprung or unsprung disc? If you have the part number on an invoice that will tell us. I am trying to get opinions on what is working well.
