Thanks BJspecB, I rang a Subaru parts bloke who gave me the information without questioning why I wanted to know. It turns out the WRX STi clutch is a different part number. I guess it makes sense as you'd expect the 3.0R-B would have a different flywheel to the 2.5 Turbo. I can't find any aftermarket clutches online under Liberty or Legacy searches so I'll go with Subaru genuine. They weren't quite as pricey as I remember $715 for the kit. It is tempting to lighten the flywheel and put a more heavy duty clutch in it but I think it will impact driveability too much and make it harder to sell the car when it comes time Cheers

G'day XoN,
Thanks for that
I see the part numbers are fairly close but but not identical.
I've decided I'm not going to chance freighting a part from the US to risk it being wrong, while the car is sitting around in pieces.
Why do you ask about the slave cylinder? Looks like a cross between a shock absorber and spray painters gun?
Cheers Dan

Thanks Again XoN,
You know your topic!
I'll still be going with Subaru genuine but the information I've got is appreciated.
I'm new to this forum stuff, what's the deal with karma & how do you get it or pass it on?
Cheers
Dan
