which clutch?

[Woods Crasher]

Well the clutch is slipping on the CA18 and I was looking at Enjuku's site and they have the Spec clutch for the CA. Out of curiosity I check out the spec they have for the KA. It looks like the one for the KA is cheaper and holds more power.

CA Spec stage 3

KA Spec stage 3

So should I just take the dowels out of the flywheel and use this KA stage 3? any reason why I should go with the CA18 Spec?

if ur going to use the ka clutch ur going to need to remove the pins AND drill out the bolt holes.i ran into this problem about a month ago haha. works great tho so go with the ka if its cheaper/stronger if u can do the work

If your going to do a spec, do a stage 4 for the CA. I took someones advice and did just that, and I was after a 3 as well.

My pedal grabs a bit high up in its sweep, but I havent attempted to adjust it yet.

It looks like it's an unsprung clutch. Won't that put a ton of stress on the trans?

So I'm ordering the clutch. Why is it that you recommend the unsprung stage 4? Won't it be harsh on the trans and have a real harsh engagement? What's the advantage of an unsprung disc? Am I really going to need that on my daily driver?

A unsprung is a bit harsh for a daily driver. At least thats just what I think.

I know this is a little bit of topic but i thought it might help. I'm using the Centerforce DF clutch for a KA and indeed you have to remove the dowel pins and drill the holes out a bit. I wasnt expecting this at the time and was worried about balance and vibration coming from the pressure plate, flywheel, etc. Point is i got it on there and ive driven the car without any issues so far. I've read on here that a specific "CA" clutch like for a CA18ET, CA18 for example, will bolt on without any modifications. I wish i would've gone with that route but I'll just have to see how long this clutch lasts.

The Centerforce DF clutch feels great! The release is a little bit after the bottom of pedal travel and feels like stock. I kept the commonly bypassed "clutch damper box" and everything seems great. Besides the bleeding of the clutch system its all working the way it should! I am really happy with the way the clutch feels, very much like my old factory setup. I've also read that the SPEC clutches release more towards the top and the DF isnt like that. Oh also the clutch disc is sprung. If its a daily id say you probably are going to want it sprung as an unsprung disc will have a harsher more intense engagement. As you might already know, the springs are there to cushion the blow so without these more of the force will be transferred throughout.

ithats the clutch im using too and it is excellent for daily drivers. ive got about 50miles on mine and no problems at all.

Illegal Garage is an option if you're willing to wait for it to be made. Mine took about two weeks, but was well worth it:





Copper on the flywheel side, Kevlar on the pressure plate side. Cost me $311 plus shipping. The owner of Illegal Garage, Max, has the clutches made by a place local to him called Superior Clutch according to his specs. At least that's my understanding of it. Since my engine is still in several pieces right now (just got it back from the machine shop! Woo!) I have absolutely no idea how it'll feel. Looks to be quite badass though, and the price is comparable to a SPEC.

I ended up going the Illegal Garage route after being completely and utterly irritated at looking at parts that "fit" the CA18DET. I wanted a clutch that *fit*, wasn't SPEC, and didn't have to imported.
