tyres size
 

im going to buy a set of rota grid drifts 18 9.5j but what a good size profile to go i wanna go low ive got the bc's fitted already

Newage or classic?, i assume newage as 9.5 on a classic must be a pig.

Be prepared for rubbing problems with a 9.5" if you go low and don't have the camber. Some people run stretched tyres to help with clearance but its not something i'd want to do...

245/40/18, 245/35/18, or 255/35/18,but as above which model Impreza are they going on?As extensive arch modifications will be required more say on a classic.Stretch tyres just don't go there:angst:.SJ.

Just to add tyre selection i.e...which model/make of tyre you choose,will also have an affect on the fitment look etc...SJ.
