Hi. I'm Mach V Dan. At the invitation of moderator @mike-tracy, I am duplicating my wheel spec thread from NASIOC. I intend for this thread to be a comprehensive database of Subaru OEM (original equipment manufacturer) wheels. I give as much info as I can about each wheel, and a picture of each.

Please keep this thread to wheel specifications ONLY. Please do NOT ask or answer questions here about what wheels fit on what cars, or what's the best wheel for your car. Ask those in another thread, or start your own thread.

If you have solid information about any of these wheels, please post and I'll update the entries as needed. Ideally, I'd like to see wheel weights derived from an actual wheel sitting on a calibrated scale. (That means something like a shipping scale, not a home bathroom scale.) In the absence of that, we'll take what we can get.

All wheels are CAST aluminum unless otherwise noted. All are 56.1mm centerbore. (I don't plan to list Subaru SVX wheels here, but they are 57.1mm centerbore.) Also, all 18" STI wheels will fit both four-piston and six-piston STI Brembo brakes, but the 2018 19" STI wheels will not fit over four-piston STI Brembos. If not otherwise noted, wheels do NOT clear Brembos. Model years shown are my best attempt at showing the FIRST model year the wheel appeared, not EVERY year they appeared.

Please feel free to post additional information here. I'll list everything back to the GC-chassis wheels if we can get all the info together.

There's the old Rays RE B20s which came in varying setups. 17 x 7 +48, 17 x 7 +53, 17 x 7 +55. The ones in the picture are 17 x 7.5 +53. They came in STI and non-STI flavor. I think just the decals and center caps were the only difference between the two. Believe they were optional wheels for the late 90s GC8, Legacy, and Forester. Not real sure though.

Can anyone explain why the Enkei's are heavier? They seem to be the same size and offset and bolt pattern. The enkei's also seem to be rarer and more sought after, but if they're heavier I'm trying to understand why? Is the weight difference because of the tires or are these specs only the weight of the rim?

Size, offset, and bolt pattern don't matter for weight. Wheel design and how it's made is what matters. The STI BBS are forged, while the Enkeis are probably some kind of casting. Because of that, the BBS will be stronger. That'll allow them to have less metal on the barrels, spokes, center section, etc.

So in theory then, the 04 5x100 wheels are the best ones because they're forged and also the lightest? It's just odd to me that the 05 model would use heavier rims. Seems backwards which is surprising to me. I assumed that over the years they would optimize the rims to be lighter and stronger but it doesn't seem that way on paper at least.

It's even weirder that the jdm Enkei's are more sought after when on paper they seem worse for performance. I feel like I'm missing some info here, bc it just doesn't make sense to me.
