Default Wheel and tires sizes for the GC8?

I could not find a thread that lists what wheel and tire sizes will fit the '98 - '01 RS. Before people get mad and post up the search link, could someone be kind enough to just post the link to where I can find this info.

Thank you

It's 5x100 PCD, so wheel selection is not too much different than the GD WRX. Factory wheel/tire setup is 16x7" +53 with 205/55-16 tires.

225 tires on stock offset wheels will be really close to rubbing in the rear, both on the fender and the lower strut perch (depending on the tire). Front has room for 245's (a few autocross setups have gone this route). Roll the rear fender enough and there should be room for 225+ tires. Alternatively, run spring rates stiff enough to keep the tire off the fender (not reccomended for lots of street driving).

I use RE-070s on '04 STi BBS wheels. I ignore the rubbing in the back because it's an autocross only setup.

Thank you for the reply.

I'm having a hard time finding more than two lowering springs for the GC8. So far I've found Tanabe GF210's and some Prodrive P1's. Are there any others?

I'm using STi Tarmac/Gymkhana springs with Koni inserts. Minimal drop (about 14" front and rear for me) and the highest spring rates available for a GC fixed perch setup (286 lb/in front, 274 lb/in rear). Works great for local autocross and isn't bad in snow.
