Default HRE 18x12's won't fit

Was putting on my new 18"x12" wheels and even though I have a 2.5" tub on each side I found out the wheel wouldn't move after I bolten them on. I lowered it back down and pushed up and down on the rear to help it settle. Inspection revealed it hitting the upper a-arm.

What are my choices here? "Grind" clearance the upper a-arm or raise the car up some in the rear? I have lowering bolts in the back with no bushings, but I would think raising it up would actually compound the problem.

-Jeremy

I would do a little bit of both. I am sure you got used to the sweet look of a lowered car but I would not want to grind off too much of the a arm. I have 18x12's in the rear and they just clear by about 1/4 inch or so and I did not have to grind. The car is also lowered about 1 1/2 inches. Good luck :seeya

Jeremy,

Stop by the shop I will give you a set of wheel spacers, to get it over here, and we will take care of it.

Thanks Lou, I'll do that.

I guess I have become helpless nowadays since I can't even install wheels on my car anymore. :crazy:

Jeremy, grinding the a-arms will do the trick. I had to do the same to mine but its not a major problem if you do nothing at all. The wheels will only touch the a-arm when the suspension is not loaded.
We have a set of center caps on the way to you also. ;)

I am having my HRE 547's, 18" X 11" increased to 12" in width. What is the minimum tub that will give proper clearance? I have Michelin Pilot Sports, 345/35/18. My car is lowered about 1 1/2" in the rear.

From the looks of mine though the minimum tub would be at least 1.5". With my 2.5" tubs I think I could fit a 18"x13" rim in it now.
