Which 18" on an STI V5
 

Hi,

Which 18" wheels can I put on my STI V5 that will not require any mods to the arches - the car does get heavily loaded on corners!

18x7 or
18x7.5 or
18x8

And will I be able to lower the car by 30mm without an problems?

What offset should I look for and can I run with 225/35/18 tyres on these? I will go for a big brake conversion too so I need good caliper clearance - does offset affect this?

Cheers
Paul
