Offset: How do you calculate it?

[Kor]

When ordering wheels, how do I know what offset I need? I understand what offset is, the distance between the center of the wheel and the mounting surface. I also imagine that you need to match width with offset so that the wheel doesn't hit the fender. Is clearing the breaks also an issue? In any case, maybe someone can post up a Mk4 offset rant for me

Re: Offset: How do you calculate it?

Now I find offset a little on the confusing side and I have spent some time dealing with it because BBS LMs are a crazy offset and I have been trying hard to find a right answer if things will fit.

Anyway MK4 wheels generally are around the 32-35 range for offset and you should have no issues. The shape and style of the wheel can effect the fit with curved spokes having different offsets in teh center and the rim, however if you stay around that range you will be fine. If you have larger offsets such as 40 then you can use a spacer to bring it back to 35, but you still need to make sure it will work with the fenders adn everything else involved.

A pic for those who need a refresher on offset

This is regardless of wheel width? For example 8 vs 8.5 vs 9 inch widths? Because a wider wheel would need to be... well offset differently wouldn't it?

Man I wish I could afford LM's but I will have to go with a knockoff

Re: Offset: How do you calculate it?

Offset does not change with width because the center is the center. However fit will change with the width because if you have the same offset and a wider wheel then you will have more wheel on the suspension side and the fender side so you may need to adjust with spacers to make sure things fit well. But you can fit 10" wide rims on the rear of a mk4 no prob so you have room to play.

I am not sure if I should be affording LMs either but the key is can I fit wheels with an off set of 5 on my car with out flairng the fenders.

I think it depends on where the extra width is constructed. If you find 2 diff width wheels with the same offset, you know that the backspace is gonna be different and you may have problems in behind the wheel.

Super Mesh's look nice on black cars!

Re: Offset: How do you calculate it?

mine are 18x8 with a 35mm offset. no rubbing or any problems whatsoever. so that for sure is perfect w/ a 55/40mm drop.

my wheels are 18x8.5 with 13mm(roughly?) offset in the back. this acts like a 22mm built in spacer on each wheel.

Yeah Ryan I fell in love with them after your initial post a few months ago. I will probably order them right after the holidays if I can find somewhere with a good price. Any suggestions?

I am thinking 8.5" width in the front and back. Obviously this is fine in the back, but does anyone know if this will be ok in the front? You can get the 8.5" width with a 2.5" lip, which will be awesome! Just gotta be really careful with them.

Re: Offset: How do you calculate it?

i was gonna order mine through tiretrends.ca

but i also found out that a local place here sells axis wheels (pasted from outlook note)

Thanks Ryan appreciate the advice!

Re: Offset: How do you calculate it?

Kris 8.5s should be no problem in the front. Contemporary is a good place, it's in T&T Honda, generally more Japanese style stuff but they have good service.

Simon 13mms eh, well that means I only have to stretch another 8mm maybe the LMs will work. What is the offset on the 10" wides?

Re: Offset: How do you calculate it?

my RHs are 18x8.5 35et i beleive.. i still have to phone glen up sometime in the next week or so to pick them up

this is a pic of my 8.5's with 13mm offset to help you decide.
