Default STI clutch plate w/ WRX Pressure Plate and Flywheel in 5 speed

I'm replacing my resurfaced lightened Exedy flywheel with a resurfaced stocker in my 2002 WRX with RA gearing to hopefully gain some driveability back. I figured while I'm in there I should replace my 20,000 mile old clutch plate, throwout bearing and pilot bearing, but instead of buying the whole clutch kit, I'd like to just reused the pressure plate. OEM Exedy STI clutch plates seem to be wickedly cheap at the moment, $57 shipped on eBay. Does the 10 mm diameter difference matter to the pressure plate and flywheel? Can they accommodate the difference? Is there a thickness difference that will be a problem? I've searched and have not found info on the intermingling of clutch parts. Any help would be appreciated.

Thanks.

ebay.... you get what you pay for.
I would think that a smaller clutch disk would wear funny if not out quicker at the outer edges as the p plate wouldnt have a flat surface to rest on across the whole p plate.

I'd do it right the 1st time so you do not need to pay to redo it all over again.

The STI clutch disc is larger in diameter than the WRX one (241 mm compared to 230 mm). What is the tolerance on the diameter of the pressure plate? The flywheel has enough clearance diameter wise.

As for the eBay comment. It's an OEM Exedy clutch disc, I'm sure the quality isn't a problem.
