Hi guys,

Sorry if this is a question thats been answered many times, but I need advice.

I'm running ~350bhp in MY99 STI and the clutch needs replacing.

Whats my options?

I've been in touch with Exedy and they recommend 1 of the 3 the following...

Any advice on these or other options?

Thanks

save yourself alot of money and just get the Stage 1 organic sports clutch kit. http://www.exedy.co.uk/index.php?mai...my_page=sports

get the one with the 'organic' friction plate and not the stage 2 'paddle' friction plate.
Here are the torque ratings for the various exedy clutches (for an EVO 6 to 9, but will be similar, maybe bit less for a 5 speed scooby). http://www.exedy.co.uk/techinfo/EvoSpecs.pdf

As you can see from the link for road and track use the stage 1clutch is more than enough, but remember that it's the torque and not the bhp which the clutch needs strength to handle.

Their are two different stage 1 kits. One is a standard kit which has a very light pedal and is good for every day driving, the other has an cover plate that has a higher clmping load and a slightly tougher friction plate and is still good for every day driving but the pedal is a bit stiffer than the standard kit. This friction plate comes in a pink box btw. Just make sure you source the kit from a reputable dealer as there are many copies out there. Try PM'ing 'Harvey', he did me a good price on an Exedy kit.

Thank you very much apac, it looks like the Stage 1 Organic will be perfect.

I had a Nissan 200SX which was pushing ~350bhp and I got an Exedy clutch with the 'tri-plate' as seen in the pics in that link. The clutch pedal was a bit harder to push down and had a really strong spring to it, but I really liked it and would love that again

So you say there are 2 different stage 1 kits, which is the one as in my old 200SX with the slightly tougher friction plate and harder pedal? ...is that the one with the tri-plate?

No, it's a single plate clutch, no need to go for a twin plate etc.

I think it's this model, but best to check when ordering... http://www.camskill.co.uk/products.p...10b0s2604p2649

Thanks again apac

The description below from the link sounds like its the one I'm after, harder pedal so not traffic friendly, but thats a good trait in my books


And its got a 40% increase in clamping load which sounds good.

Hi Alex,

Back on the road finally? Must be pleased

We have the one that you've linked on the shelf as well as the Exedy Racing Organic Anti-Judder version. The latter is more popular and nice to drive.

http://www.superhids.co.uk/exedy-clu...der-230mm.html

If you can stretch, it is well worthwhile going with a forged lightweight flywheel too. On special at the moment at just £200 more.

You're welcome to pop in and collect too.

Pedal won't be harder from my experience of these clutches over several years. Pedal feels much like it did with the OEM one.

Hi Bob, yeah its wonderful being back on the road. I'm over the moon!

I'd really like a lightened flywheel to go with it actually... £200 will need thinking about tho, but do you know the weight differences of the OEM and the lightened one??

As per the link: Thats the right part number - FK01H1601 and in the pink box

I'll need to wait til pay day at the end of the month b4 making any purchases. I'll give you a shout then Bob

Altho I am heading up to Harvey in Oct so may get it done thru him, will see what unfolds.

Thanks guys

OEM flywheels vary between 2 weights iirc, the lightweight forged ones we do are less than half the weight of an OEM one which results in a very nice improvement. Lightweight forged flywheels (more expensive) should not be confused with OEM lightened versions (cheap).

The part number you've listed is the original Exedy Organic Racing clutch which does have a tendency to judder, although a very good clutch. Also, the term "pink box" is a dated term now which used to distinguise a OEM version to a Racing version. They all now come in the same coloured outer boxes, all the inner friction plate box is still pink.
