Default STi brembo brakes with Subaru's 16 inch winter rims.

I have done a search for this, and did not quite find the info that I was looking for.... But my question refers to using the STi's Brembo calipers and discs on a WRX with Subaru's 16 inch winter rims...

Now, would it be possible to use these wheels WITH spacers with the STi Brembo brakes?? Or is one really consigned to using 18 inch rims for winter in order to use the brakes??

Thanks in advance for the responses.

Hehehehe.. good luck. A 16" wheel will just not fit over the calipers. Not talking about the spokes, I mean the actual circumference of the wheel, the caliper will be rubbing along the inside of the wheel.

You can use a 17" rim very easily though. The SDR's make perfect winter rims, not too expensive, and still retain good looks (IMO).

So sorry, but no on the 16"ers

This just had me thinking... why don't they make rims w/ extra clearance? Probably just lack of demand, but is there anything from preventing someone from designing a 16" rim w/ 17" sized internal circumference? That is, the inner diameter of the rim, at the centerline, is larger than the diameter of the lip...

wait, I guess you wouldn't be able to install or remove said wheel, if the brake rotor/caliper really required the space...

Well, now, come on: the original question stipulated spacers. Sure, no 16" wheels will fit without 'em. But, hey, 8" (or, say, 200mm) spacers would make the 16" wheels stick out far enough to clear the brakes, wouldn't they?

We have lots of cars here in Santa Fe with that look, often with 12" wheels and low profile tires. I think of it as the go-cart look. HPH

Get 4 of the wheels used for the spare and mount some of those super skinny rally snow tires. The ones that look like motorcycle tires.

Good luck with that - there was someone looking to buy a spare with no luck a few days ago....

And even if you could find those weird spare wheels, I don't think they fit on the fronts of STis. I recall reading somewhere (maybe -- gasp -- even the owner's manual) that if you get a flat on the front of an STi, you're supposed to take off a rear tire, put the spare there, and put the rear onto the front where the flat is. Serious PITA, if you ask me. HPH

I would think that having a missized temp tire in the rear would cause more damage to that axle's diff because it isn't the same rolling diameter as the stock 225/45-17 tire?

Unless of course it is the same rolling diameter...

It may be more of a safety/load issue for a heavy car though.

It fits fine in the front:


EDIT: Oh yeah, and the rolling diameter is damn near identical to the stock wheels/tires.

There is actually a 16 inch rim out there specifically designed to fit over the Brembos. I can't recall the name right now, but they are ultra rare to say the least. If I were you I would just pick up some Rotas in 17 inch and be happy.

You don't need to do that. If you can fit a 15" wheel over a 310mm rotor--and you certainly can--you should be able to fit a 330 mm rotor (less than an inch larger) inside a properly designed 16" wheel. This shouldn't require warping space and time or designing a trick, hollowed out wheel.

There's obviously demand from any STI owner in a deep snow region or who rallycrosses. Hard to understand why a manufacturer hasn't stepped up and made a wheel to fit. I could see demand for a strong 16x7 wheel--perfect for 205 or 225 snow tires or Pirelli's K series 16" gravel tire.

Yep - fits great! If you look at the spare, they had to go through some contortions to make it fit over the brembos. There's basically half of a "donut" through the circumference of the rim where the caliper sits. Pretty neat.

And actually, seeing my car with the donut made me really really think about getting some black or gunmetal rims. I liked it (you know, considering)

to bring back a thread from the dead (hey at least i use the search button, complain one way or the other but not both!)

just like the donuts/spares have a raised section to clear brembos why can't we do that with some other 16" wheels? the inside could bulge at least as much as up to the lip, maybe a tiny bit further. would be slightly harder to mount tires but the rims would mount fine, the caliper is only on 1 part of the rotor... so you would just lift it over the rotor and then work it down onto the studs. anyone know of wheels that would clear spoke wise but are too small the other direction?

any suv's with big brakes like the crv but in 5x100 and not 5x115?

Any news on this topic? I really need 16" wheels on my 2011 STi for wintertime... But don't want to f*ck around with small brakes... :/ Will Braid 16x5.5 +40 fit? What brand? Anyone?

No 16" wheel will clear STI Brembos. IF you want to keep the Brembos, start looking at 17" wheels and tires.

Indeed. Steeda used to sell a 16x8" wheel that cleared the PBR Cobra brakes (330mm rotor with a dual piston sliding caliper). I've seen pictures of 16x7" Crown Vic steel wheels over the same brakes - apparently they required some light clearancing on the caliper "shoulder", so with a small spacer they should've been fine. I've personally test fit a 17" mini spare on my CTS-V, which has 355mm rotors and the same Brembo caliper family as the STI. If the CTS-V's ~14" Brembos will fit inside a 17" wheel, then logically the STI's ~13" Brembos will fit inside a 16" wheel.

So, as if often the case even with 17" wheels, it comes down to spoke clearance. Fixed calipers typically extend less beyond the outside diameter of the rotor than a sliding caliper does, so the STI Brembos on a 326mm rotor should fit inside the barrel of a 16" wheel. But finding a wheel that has the spoke design to clear the fatter fixed caliper is the problem.

9 years later as far as I know nobody has ever stepped up the plate. And so few cars and trucks these days even come with 16" wheels that the chances of finding some random OEM fitment that will work is very slim.

It would be interesting to see if the mid-2000s (I think '03+ or '04+) Crown Vic wheels (either steelies or alloys) would work with a spacer. From what I can see searching on Ebay, they're 16x7 +45mm, so you could run a pretty big spacer to get the caliper-to-spoke clearance.

Best bet would probably be something like an r32 gtr wheel. They come with similar 4 pots and apparently fit on an r33/34 gtr brembo brakes with minor clearance... Finding them isn't the easiest (have to be gtr wheels, gts are different) and they're not cheap when you do. Best just to go to 17". The CRV 17" steel wheels fit... a lot of people on here run them...

Oh ya and good search skills.

There is a 17" braid gravel/snow wheel that will work on a Sti. only thing is they are on the heavy side. About the same weight as the stock 5 spoke 08+ Sti wheel 27 28lbs.

Was thinking about picking up a set after I get my gravel/rally coilovers
