Edited my post, typed too quick. Its gonna be a little tighter but with the lower profile tire it should be fine. Try to find a "wide" 225.

Stock tire height = 24.9"

Several options:
225/40-18 25.1"
235/40-18 25.4"
245/35-18 24.8"

I guess you could add 255/35-18 too at 25.0"

265/35-18 25.3" This is a crazy wide tire but is reasonable(not terribly off) height-wise.

The S203 come stock with 235/40/18, 265/35/18 is the same height as the 235/40/18.

As far as I am concern, WRX, STi and S203 all have the same chassis

You make a persuasive point.

.....d00d.....wake the hell up.

The WRX and STi are COMPLETELY different drivetrain.....GOT IT????

The gearing, in and of itself, is 100% different.....as is available power.

Put the wrong size, too tall/heavy wheels and tires on a WRX and you KILL acceleration and handling....or does that escape you????

WAKE UP......HELLO ? ? ? ?

Scotty, are you serious that you think a 1/2" taller tire is gonna kill performance? I cant say that I agree at all if so. Negligible effects versus 225/40-18 IMO. Now going from a 16 to an 18 to begin with will have noticeable effects.

If youre railing on the 265s, I do have some doubts about that much rubber being a good thing.

I would say I might have lost 1/10 to 60 on a 2.2l fwd wagon. In perspective, I dont think even the famous buttdyno could register the difference between a 225/40-18 and a 235/40-18.
