[/B] Ok, so I buy a set of 20mm spacers to get my wheels even with the fenders. Tooling down the highway I hit a low area and feel the right rear rub my fender. I know its not the spacer that caused this, I'm sure it has something to do with a bad spring, strut, shock... It's an 06 with 30k, bought the car with 3k......any ideas would be greatly appreciated

 

are you lowered? How low was the low area? need more details.

 

just keep driving........it happens...

but ya may wanna roll your fenders..

 

stock suspension, 275/40/18 on the rears, area was not that low, more like a dip

 

Could be the spacers. I'm dropped on NF210s, 25mm spacers, oem 5-spoke 18s, and rubbed like crazy on one side until rolling fenders.

 

rolling fenders is not an option, maybe go with a lower profile tire, or maybe upgrade springs..... I have not had any rubbing anywhere else, why just the right rear??

 

Im on 25mm in rear and never had a problem..

 

The fact that you spaced the wheel out 30mm from where it was before is what caused it. The cars don't all come with the same alignment settings from the factory, and since tire sizes also vary (not all 275/40/18 are the same physical dimension for example), some cars will rub, others won't. It really is all the luck of the draw many times.

Your options that will absolutely work:

fit smaller spacers
roll the fenders
narrower tire

options that might work:
more negative camber (also affects toe, so do this carefully)
shorter height tire
lower springs - I put this in the "may" catergory, because while you will get a more negative rear camber, because they are lower, you may find yourself now hitting that rub limit more frequently

 

thanks Z1, I think my best option will be to go with a smaller spacer 1st and then a smaller tire if needed.....thanks for the help

 

What are your offsets now? If your running low offsets your probably going to rub. Just go roll your fenders. It's easier and cheaper to do that than go buy 4 new tires.

 

offset are +38 at all 4 corners, I'm running 20mm spacers up front and 25mm rear, how hard is it to roll fenders?

 

If you know someone local with a fender roller they will probably do it for cheap, but a shop will usually charge like $200. It's not hard, all they do is heat it up and roll it with the machine. Not more than an hours work.
