Default STI offset, wheel info

New to the Suby world.
Coming from Audi S4s and BMWs

Probably going to pick up a 2008 STI in 5 weeks or so.

Was looking at putting these on a DGB or Silver STI


18x8.5 and et47
I was thinking 265 Pirelli PZero's or Mich PS2s to keep unsprung weight to a minimum and have great grip.
Loved these tires on my Audi's and BMs.

Will this set up give me a more aggressive stance and not rub ?
I don't know the stock offsets and what room there is under the fenders.

I don't want to rub or roll anything.
I'll probably do a set of CO's with custom allignment (-2.0 camber)
Lower the front a bit, but probably keep the back close to stock height.
I don't like tucked, just a 1 finger gap.

Thanks for the insight.

made the mistake of ordering 18x9 et45 when alot of people have gone 18x9.5 with lower offset like 39 or 37 with 265 they have not experienced any rubbing regarding the zr 520 i think i read somewhere that Clap mentioned it might have problems with clearing the brembos plus the wheel is so heavy at 25lbs you might want to look in to that. stock offset of the bbs or the stock sti wheels are 18x8.5 et 55.

What about using 18 X 8.5 offset +43 would that fit without any trouble? What if i want to lower it some more, now would there be trouble? Or shall i go smalled like a 34, or 37?

dont have the specs of the stock but most forged wheels with that size weigh from 17 to 19 lbs. at least the one that i had before. the zr520 i think is cast.

good point...... didn't think they were cast..... but, then again, at $340/ea, they gotta be.......

Forged is the only way......
