This sucks, I didn't want to use any wheel spacers and I was under the impression they would fit according to Tire Rack. They are 18x7.5 with a 48mm offset. I've never used wheel spacers, how much does it look like I will need? I have 75mm wheel studs installed.

 

Looks like they would be fine, if you were still running the OEM shocks and springs. My guess is 8-10mm to clear the spring.

 

 

Remember, the more offset of the wheel AND, the more additional spacers added, the more the front tire will "scrub" in the corners rather than tracking smoothly with no sliding or..."scrubbing". Simple physics, proceed with caution if you want to maintain good handling.

Those look great. Can't wait to see it all put together.

 

You're probably good with 5's, but I'd also get some 7.5's to make sure. I'm going to be running, in most likelihood, 5-7.5mm front and 7.5-10mm rear spacers to get my own wheels situated. 17x8 et45 949Racing 6UL - front looks about the same, though I'm waiting on my coilovers to arrive for further fitment. I'm also running a stud conversion, using I think 90mm studs from Turner (though they've been in my garage for 6-7 years now).

Beyond that, if you're concerned, ECS has a sizing kit: https://www.ecstuning.com/b-ecs-part...01202ecs03a~a/ Or $140 and you get $120 store credit back upon return.

Spacers are fine, people that are unknowledgeable about them don't like them. I've had plenty of experience with spacers from 2008 to current, and never had a problem. And this includes running a VW Tiguan on Ohlins entirely too hard around some canyon roads that I used to use on my motorcycle.

EDIT: What tire size are you running? You really need to get at least one tire on there so you can determine actual fitment room / potential issues.

Spacers are fine in the back. Can be used in the front...IF...done with care. An offset wheel AND spacers do NOT make up a proper steering car. It's simple 7th grade geometry..!
Me thinks someone needs to do some homework on front suspension geometry..! Get a good book...read carefully, go over it twice if required.
And he says "I'M" unknowledgeable. It appears the "pot is calling the kettle black" in this case..!

Welcome to the internet, don't take things so personally.

My statement is based on safety, as I don't care about his lap times. As such, my statement stands.

 

Not taking it personally in the slightest. I really don't care. Not my car..!
I was just advising. If you want second hand handling, wearing tires more than normal...go for it.
As such, your comment adds to lesser handing characteristics...period. If that's what you like saying to folks. And you comment DOES say something about performance. Reread your comment about haw well it handles in the canyons. I'd think twice about saying how well your car handles in the canyons...when in actuality, it COULD handle a lot better..!

is this why the SMF autocross cars run big spacers and 275 front tires that stick out 6-8 " ?

OP, I run 10-15mm on my track car to keep the tire from hitting my coilovers, same spot yours will it if you test fit with a tire. If you run 10mm you have to machine the hub, there are some spendy 12mm that work without machining but I like to stick to the 15 $ versions I can get cheap

 

Could you elaborate on why </= 10mm spacers require hub modification? I am planning to run between 5-10mm spacers on my own setup, so would like to know what I have to look forward to. Thank you.

 

You only have to machine the hub if you want the wheel to be hub-centric. The part of the hub on the car that protrudes is 10mm, so with a 10mm spacer the wheel is no longer hub-centric.

 

Perhaps I'm not understanding this fully, but given that every quality spacer is also hubcentric, would this still be an issue?

Looking further (at a retailer), I see that 10mm is skipped completely. Interesting. I suppose it's time for some more research... I'm glad I saw this, thank you. :beer:

 

The spacer will be hub centric, but there is not enough material left to allow the wheel to be hub centric. With an 8mm spacer, the wheel can still center itself on the hub. With a 12mm spacer, there is enough material on the spacer to provide a "hub" for thee wheel to center itself. A 10mm spacer won't allow for either of those scenarios.

 

the OEM hubs have a lip that is too tall, a 10mm spacer wont sit flush, you have to take about 1mm off the hub so it will sit flush.

afaik these are not really hubcentric, I have ran without hub adapters (forgot them at home) with no ill effects, I always run them just to make mounting easier. Hubcentric bolts look quite a bit different, no taper to them. I use plastic hub adapters there's no way they can hold weight of the car they are not even solid.

On most cars 10mm work fine, but on BMW/mini the lip is just a little bit too tall
