Default 2009 sti hatch wheel spacers recommendations

Okay so I have a 2009 STI hatchback currently with 2018 WRX Limited Wheels. I'm currently running some cheap 5mm hub-centric wheel spacers in the front to clear the brembos. I deal with Discount Tire for my tires and they will not touch them unless they are the bolt on Style wheel spacers. With that being said I am wondering how thick of bolt-on style wheel spacers do I need to run on all four tires to achieve a flush ish fitment? Also without running into any rubbing issues, Fender modifications, Etc. Any type of brand recommendations would be great as well as thickness without having to do any cutting to my original wheel studs. Thanks in advance for all the support.

Keep in mind that the THINNEST bolt-on spacer (with its own built-in studs) is 15mm thick. With a 15mm or 20mm spacers, the stud and/or lug nut will poke up beyond the new spacers, so you wheels must have clearance to fit around them. Not all wheels do; I don't know about yours.

As for slip-on spacers -- as long as they are quality spacers, I don't have a problem with them. Note that beyond 5mm you will need longer studs.

Dan,

I also do not have an issue with the current slip-on hub-centric wheel spacers. However Discount Tire refuses to touch the tires because of them. Which is why I'm almost being forced to go with the bolt on Style. So even if I were to get the 15 mm bolt on style wheel spacers that was still require me to cut my stock wheel studs? What about the 20 mm?

Time to go somewhere else.

It depends on your exact wheel, and how much clearance it has on the back side. The studs AND the lug nut will poke up beyond the surface of a 15mm wheel spacer, like so:



If your wheel has cavities in the back, it MAY be able to clear the stud and lug nut, but it may not. This STI BBS 17" wheel has cavities but they are not very deep, and probably will not clear the stud in this case.



You could trim the stud, or Dremel out the wheel a little bit (at your own risk!), or use a thicker spacer.

I see thank you for the pictures that makes a lot more sense now. So how thick of a bolt-on style wheel spacers should I go while possibly not having to do fender modifications? Also how hard is it to really cut the stock wheel studs slightly to get them to fit inside of the wheel spacers? Is it really that big of a pain cuz I would hate to do it and then end up stripping out the nuts that they come with.

I suggest you don't use spacers.
