Well I finally got my RS 1.0 last week and now the hunt begins for wheels. My question is, where would a 18x7.5 or 17x7.5 rim sit on the XB? Would it be in the wheel well or sitting flush with the car? I really want to get a wheel with a lip. I have seen many of you speaking of putting spacers on the xb. Is this a safe pratice in a high pothole area such as NY? :

 

The real factor in determining if a certain wheel sits inside, or flush with the wheel well is the wheels offset. This is the number that has either a + or -, followed by a number...typical ones include +35, +44, etc...however they do come in - offsets as well.

Higher the offset, the more inside the wheel will sit...on Scions, it has come about that anything higher than a +44 will start causing problems such as suspension rubbing...definately not good.

A good aim would be for +35 and below...it will be safer, and at the same time help the wheels look bigger and better as they will sit more flush with the fenders.

 

JDMxB,
Thats only true for wheels of the same width. A wheel thats an inch wider would like an extra 13mm of ET in order for the outside of the wheel to sit on the same plane as the wheel its replacing.

After test fitting a few different wheel setups it's become pretty clear that if you're goal is for your wheels to be totally flush, you'll need a staggered fitment. That's also why you see a lot 8/9 setups on bB's. That's not to say that they can't be flush without going that wide. You'll just need ultra low staggered offsets. For example, on a 7" wide wheel, you'll need an offset of +25 in the front and something like +15 in the rear.

Peace,

Maybe i'm blind--but didn't he ask for 18x7.5 or 17x7.5....Um, if they don't specify, I would assume that they are going with the same width wheels all around.

All my information is concerning a 7.5 inch wide wheel--which is exactly what he asked for.

 

Does anyone have an opinion on his question about spacers and their reliability with potholes and such? I'm thinking about getting a set of 15's for my rears when I can affrord them but, if anyone has experience riding on big spacer's cares to share thier thoughts...Thanks!

I got H&R spacer (front 15mm,back 25mm) totally safe, and tested on BQE,Grand Central Parkway,LIE, Whitestone brige,GWB,FDR,West side Highway, Midtown tunnel, etc and my local streets... :D
