Fitment opinion
 

So I was wondering if anyone can vouch that my planned setup will fit reasonably well... there are a lot of combos out there and I haven't found a specific post with anyone with the following combo...

Stock 19" Rays
15/20mm spacers (front/rear)
Swift Springs
305/30 rears
275/35 or 265/35 fronts (depending on what is available)

I don't own anything except for the Rays obviously so I am flexible but I am pretty sold on the spacer width and springs so really I am just wondering if that tire setup will work with the drop and the spacers.

You might want to post this over in the Wheels&Tires section, also check out
the "will it fit" thread, wheel fitment guide sticky, and wheel offset sticky,
you can get an idea of how close this combo will fit.
