Spec vs ACT

[Angry7M]

So I'm looking to buy a new clutch for my 1989 Mk3 7mgte, Looking to get about 500 Whp once it's all done.

Clutch Options:

ACT:
Torque rating of 522 ft/lbs.
Disc Material Ceramic

Spec:

Torque rating of 520 ft/lb
Carbon-Graphite Friction Material

Which should I go with? I was wondering which would hold up better and better quality. Also the diference between Ceramic and Carbon? Durability?

ACT.

If you want a Twin-Disk, Spec is the way to go to hold enough power before the R154 gives up.

I have a Spec stage 2 and never had a problem with it. Not sure if the controversy is still around, but when I was researching clutches some people said that Spec uses an OEM PP painted blue. The pedal feel with my stage 2 is no different than stock.

 

[Angry7M]

From what what I know all of them use stock pressure Plates but there suppose to be modified for higher clamping.

Are you planning to do any drag racing?

 

[Angry7M]

Yes Sir

Daily driven once in a while and weekend Drag Racer, im a really heavy foot though.

Get a better clutch then. It is better to get something that is not just a little above what you need. The reason for this is because drag racing and slipping the clutch adds a lot of heat and stress, so if you are making 500TQ, get a clutch for 600TQ. It is the same concept as fuel, always want more than you need.

I actually have a HPF clutch disk and ACT pressure plate that will hold all the power you have/plan to make before needed a twin disk.

How much does that HPF setup run for?

Good point on getting a higher rated Tq clutch setup, would be nice to have something a bit more reliable.

Is that sprung or unsprung? what is the engagement like? any chatter?

 

[IBoughtASupra]

It's a sprung disk, street friendly.

I'm running the ACT XT pp with 6-puck sprung disk. My little torque-less 1JZ is making about 500lb/ft and its holding up great, street friendly..not so much better start working out your left leg
