Hi guys, I'm looking at buying 18" Rota Grid R's as there's too much wheel gap with the current 17" Work Emotion Cr Kai's. I can't lower my car anymore because the exhaust is already 100mm off the ground and sometimes scrapes. Will 18" wheels fill in the gap or will I need to get 19's? Also I'm not 100% on the width and offset of the wheel. I've seen Magicks setup and I really like it, http://www.sau.com.au/forums/topic/404792-magicks-na-r34/ he has 18 x 9.5 +20 all round. I can get my hands on 18 x 9.5 +18 but I don't want the wheels to stick out much at all. Also would it look better if I had different offsets for the fronts and rears and different tyre width? I've attached photo's of my current setup. Any suggestions would be appreciated, thanks.
