Wheel question

[mtoxracerfss]

I accidentally ordered +48 offset instead of +38 offset rims. They are already shipped so it would cost $15 a box (2 boxes) and another $150 in shipping to get the right ones. Heres my question...can i use small 5-10mm wheel spacers to make up the difference?

If I'm not mistaken, Mk IV rims are 50mm offset and fit fine...try them on the car (no tires) and see where the rim is relative to the shock and outside edge of the fender. What are the rest of the rim specs?

17 x 7 with 225\45's

I bet you'll have no problem

Thanks!

17X7 will have problems.
While you may not rub, you're going with a stock width and sucking the rim in 11mm. That's ~ 1/2" further inboard. It just won't look right without at least a 10mm spacer (which will need longer studs)

The Mk IV TT wheels are 17x8 front, 17x9.5 rear, both with a 50mm offset...they are used all the time on the Mk III. I still think he should try them (especially the rear)...a slightly wider tire (235) will help to cover the offset too.

It's closer to 3/8" further inboard (25.4mm to the inch)...that's not very much.

yeah, but even my 43 mm jza 70 wheels are noticeably further inboard with 245s on the back.
I'm speaking from experience. 11mm is exactly 7/16, so we can compromise
mkiv rims work because they are an inch wider up front, and 2.5 wider in back. With a 7 inch wheel, it will look "odd"

ew. 17x7? If you're gonna spend money on wheels, you may as well buy good ones.
Adding a spacer is a bad idea. It places the wheel farther outward than intended and can cause larger than typical loads on the ball joints causing premature wear and early failure.

If it sits too far inwards, how can putting the tire/rim back to stock location using spacers cause this?

Jeez Kurt...
You are correct, placeing the wheel in the stock location will have no ill effects, except that you may need longer studs...

 

[supra90turbo]

Heh. I just figured putting the wheel at the stock location may look alright, but it would be putting the contact patch further away from the ball joints than factory, therefore creating larger than normal stress loads...
But now that I really think about it, you're right, since they're still 7" wide.
Longer studs will be your only setback.

I now gracefully bow out of this thread :icon_razz
