Prodrive P1s in 18x7.5" with ET46 offset do clear the Brembos. These are the wheels Prodrive recommend for the UK STi fitted with the PPP upgrade.

Default "Do not fit" List.....great idea

WRX What,

Great idea..........I think there's another thread about "wheels that fit" but these threads very often get sidetracked by non-pertinent replies etc., so you've really got to sift through the entire thread to find useful info.

This seems like the best way of doing things i.e. a straightforward list of (a) Manufacturer (b) Wheel Brand (c) size, diameter & width (d) offset (e) do they fit ?

Maybe we could start an official thread like this with a sticky and have the moderators simply delete non-useful info. ?

By the way, I think Volk CE28Ns in 17x8" with +44 offset do fit (or so I read; needs confirming).

If you'd read the "wheels that will fit" thread, you'd have known this already.

thats Odd, I have read that thread quite often, and I saw many times that they DO fit, but never that they did not.

I guess Thanks for pointing it out then, I will have to go sift through it all again

Actually, Glenn, the first thread you posted did have the correct info in it, just on page 4. I've copied my original post here so that it isn't buried so far:

----------------------------------
Well, from what I can tell the following wheels will fit:

std JDM STi 17x7.5 (www.rallispec.com)
Prodrive OZ 10 (p1?) 18 inch ET46 (http://www.subaru.co.uk/cgi-bin/acc...ubaru&area=sw03)
Prodrive PFF7 18 inch(http://www.subaru.co.uk/cgi-bin/acc...ubaru&area=sw03)
Prodrive GC-06 17, 18 (from last post and http://www.prodrive-japan.com/english/products/)
Prodrive GC-010E (http://www.prodrive-japan.com/english/products/)
Prodrive GC-05 (http://www.prodrive-japan.com/english/products/)
ScoobySport Sao Paulo 18 (http://www.scoobysport.co.uk/wheels.htm)
Axis Battles as mentioned above
Various Volk wheels, all mention fitting the Brembo calipers (TE-37, CE-28N, Gramlite 57f) (http://www.rayswheels.co.jp/e_index.html)

I'm sure there are others, but I got tired of looking with my modem connection...

Note, it sounds like the Prodrive P1 that most people have (even in 18) has the wrong offset to work with the Brembos. The prodrive site specifically lists the 18 inch P1 with an offset of 46mm as fitting the Brembos.

----------------------------------

The difference is that the two P1s have different offsets. Subtle, but important.
I'm also told the Rota SDRs fit and that SSRs competitions in 17 do NOT fit, but confirmation of the later would be nice.

Those are Prodrive PFF7s, I think. The Rota SDRs are copies. As noted above, they both fit.

Those are actually the GC-07's. They are forged which ups the price from the Pff7's price tag of $369 to $529 for the forged. ALso, the PFF7's don't come in such a drak gray/anthracite.

Just to be clear, wheels with ET46-48 fit because the smaller offset is to compensate for a wheel shape that doesn't allow the calipers to clear.

This has been beaten to death, but you do want a wheel with an offset of around ET53 (like the stock wheels, JDM STi wheels, etc).

Using the ET46-48 wheels is an ok "workaround" for the brake clearance but can cause steering issues (see SPD site for more info http://www.spdusa.com/steering.htm).

Glenn,

What are your thoughts on changing offset as wheel diameter increases e.g. 17x7.5" to 18x7.5" ??

I've seen posts recommending an offset of around ET48 (or so) with 18" wheels, but wouldn't the standard offset of 53 be best even for 18" rims (assuming you stick with 7.5" width) ??

Diameter shouldn't have any effect -- also because typically you select a lower profile tire that has the some overall diameter as the smaller wheel.

I don't think ET46's are going to cause you to run off the road into a tree or your hair to fall out, but certainly an ~ET53 wheel is preferable if you can find it.

Thanks Glenn.

There's a bewildering array of sizes and offsets and still a great deal of uncertainty about what will or won't clear the Brembos. I think I'll probably go with something from Volk (surely they'll have the right offset) or maybe Prodrive's GC-010E when they're released over here.

OK, how about a varient of this question. If I went to 17x8.5 (1 inch wider than stock), would I still use ET53 offset?

Obviously I haven't verified that 17 x 8.5 will even fit the stock wheel well, but I suspect it would make a nice difference if running 235 or 245 tires (I'm going to assume that, like the WRX, 255s won't fit without pain and a set of pliers). I'm also going on the somewhat dubious assumption that 0.6-0.8" of extra tire (about 5-6 percent) will make a difference.

Okay a few addittions. Volk CE28N in 18X7.5 +47 do fit with 3mm spacer. +44 fit without spacer. CE28N 17X8.5 fit wioth +44 mm offset also. 17X8 does too with 43mm offset.

Other than looking for winter wheels, what is wrong with the stockers?

For me, I want a set of track/autocross wheels. Having run my Miata with Falken Azenis for a few months now, it is clear that without Kumho or Hoosier tires, I will lose. Period. It is 2 to 3 seconds a lap difference, which is enormous (OK, fine, I'll win against someone who doesn't really autocross, but against anyone who can drive worth a darn, it is bigger than anything else one could do to the car). Since I live 200 miles away from some of the events, I can't drive there on R-compounds. So I need a set of track wheels for my track tires.

Personally, I'd rather try to optimize my track wheels for that purpose (light and strong) and leave the stocks for street use than the other way around. The SSR Competition wheels seem perfect for me (light, strong enough, price isn't bad, looks good), but they don't fit (the 17x7.5's don't fit accoring to a few reports). I'm trying to avoid something like Fikse custom wheels because of the cost (2-3x more than the SSRs).

It looks like for SSR Comps in 17", gold, and 5x100 bolt pattern, I find +50 offset with 7.5" width, +35 or +48 offset with 8" width, and +48 offset with 8.5" width. If I understand wheel offset correctly, the 7.5" SSRs have 3mm of extra room, but the design is such that they don't clear the calipers. The 8"s will have 9mm beyond that, and the 8.5" 15mm. This is probably enough extra room, but we're still stuck with the +48 offset which is 5mm less than what we would like for handling.

I think I'll drop a line to Fikse and see if I can stop by their offices next month when I'm in the area and have them see what they can do in terms of fitment. HRE is another option in the same line as Fikse.
