Hey...
Wondering if anyone knows the proper offset for a staggered set of Borbet A's [16x9 + 16x7.5]. Car will be lowered 60/40 via H&R cup kit if that will make a difference?
Rims have been ordered but they will email me to check for proper offset before they ship em out

There is a "wheel/tire pro" on a N.A. website that recomends I get Et20 up front w/ 205/50/16's and Et25 out back w/225/45/16's
Is there anyone running this set up? it supposedly is closer to the stock rolling diameter compared to the traditional Borbet A E30 set up using Et15 on the rear w/215/40/16
any comments on this set up?... here is link to the thread if anyone is interested:

With a 40mm drop on the back the rears will rub even with 215/40. I am now running the same wheels on a car that is roughly standard ride height and they are fine.
Basically if you havent had the arches rolled/flared you wont be able to run a larger tyre than 215/40 with a 40mm drop.
