16x8 and 285's, what backspacing? #356936 12/03/03 01:44 AM

I'm contemplating getting 16x8 wheels and 285's and staying with the stock a-arms or getting factory 16x7's with 285's and ATS (Inland) a-arms.

What backspacing should I get with the 16x8's to avoid rubbing the factory a-arm and/or fender?

Here is what I have for suspension:
front: OME 882's, OME HD shocks, one trim packer

rear: OME HD coils and shocks

I also have an ARB Prado bar, Warn M8000, and Trailcarnage skidplates holding that front end down with the 882's.

Opinions? 16x8's and stock a-arms or
16x7 factory and Inland a-arms

4.25 or 4" would be optimal.

I rub substantially more with 8" wheels than I did with the OEM 7's with 285's. You'll have to grind down the pinch weld/body seams behind the plastic fender liner a bit in front. I don't think there's any way around it.

I gained quite a bit more room next to the upper A-arm, so that is no longer an issue.

I went to your website, those 16x8 Mickey T's look great! It says you have 4 9/16 backspacing? So, 4" would tuck the wheels farther in the wheelwells? Just trying to make sure b/c I'm not after that "skateboard" look.

Thanks!

4" would push the wheels out further. I basically have 4.25" in the front with those spacers, and it is just a fraction away from the calipers.

Ok, 4.25 is farther out, I saw some wheels with 3.75". I'll definitely stay away from 3.75" and shoot for 4.25".

Thanks.

No, I meant 4" is further out than 4 9/16". The smaller the number, the further out your wheel is.

Hey Darren I was wondering which backspacing you ultimately went with. So you ended up with 4 9/16" minus a 1/4" spacer?

Yes, that's correct. It was a custom spacer Andy (Red Chili) over here in Aurora designed and has worked for him.

Yeah, that's what I meant. I don't want them to stick out any farther than necessary. I like the tires being inside the fenderwells. Thanks again.

Okay, very good. Not sure if you saw this picture, but here is how mine fit under the flares:

[Linked Image]

Looks a lot better than with the 7" wheels filling out that area. They sit just a fraction outside of them. I'm not sure what type of flares you have, but anything smaller than the "limited" ones, they will definitely stick out further than the flare.
