    When widening factory rear wheels 'to the inside' like Weldcraft does, what is the max width you can add without rubbing on the inside or having to then use spacers, 3/4"?

    Without spacers? Not a lot of room.
    With 305's on factory 9.5" wheels there's about 1.25" between the shock and the tire.
    At full extension the tire is less than 1/8" from hitting the inner fender well at the bottom.
    Different wheel but I had a set of '12 SRT8 wheels widened to 10.5" and 305's would rub occasionally even with 6mm spacers.

    I widened my factory rims to 11" and have 315 on these rims. Kept the exact factory tire only instead of 275, they are 315. I did do a bit of wheel well work which cost about $400.00. this way I did not have to use any spacers at all. The tire fit under great and the car looks great. I actually got all the step by step procedure from a post on this very site. I am very pleased with the effort. The post was from early last year, 2015 I believe.

    By "wheel well work" I'm assuming you mean the inside frame rail and sheet metal?

    Yes, there is a triangular cover on the frame rail that is removed and moved closer to the frame rail. This gave me all the clearance I needed for the 315. Also some trimming of the plastic wheel well covers which was trimmed with the use of only a pair of sheet metal snips. If the shop you use is a good shop, they will make the job look as it was never touched.

    Good info-thanks. What brand of 315's did you end up fitting in there? The GY and Michelins run about 1" wider than Nittos.

    I actually put on the same tire as factory only in a 315. I liked the look and the difference with the width looked so much better and although I haven't been to the track, it does seem to offer much better traction.

    Nice! How much clearance does it have? Could you go any wider toward the inside?

    do you see any different in the way the car handles? grip? Any issues with widening the rims?
