So based on the noise and behavior of my clutch it seems the stock TOB has failed or is failing. I need to get a new upgraded clutch kit. I see the "spec clutches" on outmotoring.com, does anyone have any recommendations? I'd like to go above stock clutch performance!

 

I have the OS Giken STR clutch and I am kind of so so with it. It really depends on what you are looking for, like are you tracking your car or are you just street driving.

 

street driving only ever do pulls really, but with the tune and higher hp I want at least a stage 2 probably to hold up to the added power over time. I've had a stage 4 clutch on a previous car and the engagement was firmer but it doesn't bother me.

 

i just put in a clutchmasters FX350 clutch kit with single mass conversion, which is basically a stage 3+ kit. i like it. pedal is just a little heavier then stock. it does chatter a little when it gets hot. but i think if you were to do a stage 2 with a regular full face friction material you may not get the chatter at all. the 350 is a segmented carbon kevlar friction material.

 

How do you like the ClutchMasters clutch?

 

i like it so far. have had it in for about 2,000 miles. the only downside is the chatter when it heats up. i either have to engage it so the car either almost stalls or launch it with wheel spin. not sure if its because of the friction material they use or what.

also i got the lightened steel flywheel instead of the super light aluminum option. steel weighs 24 lbs, aluminum i think is 12lbs. stock dual mass is 36 lbs. i was treying not to go too light with it because i knew it would chatter even more.

 

I can deal with the chatter. I will look into that when I go to replace the motor.

 

It wasn't the throw out bearing, it was the slave cylinder! Warranty covered! Phew!!!
