TC1 Lug Shank Size
 

So I traded in my Rs5.0 tc. I had a spare set of 17 inch oem wheels with my race tires on it.

The lugs are the 12x1.5 pitch... Whats the shank size on these oem lugs.

Im using the wheels on my FRS which has a 1.25 pitch. And the FRS lugs will not work as they are acorn style and I need the flat seat for my oem wheels. So many lugs out there my head is hurting. What do you guys recomend?

I think you just answered your own question. You need the OEM style of the tC1 just in 12x1.25 pitch. Sucks that it changed to Subaru's specs.

No that's pitch. Shank size is the length. http://www.gorilla-auto.com/lug-nuts-page-14

Well, take off FR-S lug nut, break out measuring tape(or caliper), done. Let me know if what I posted measures out to work(I think it will just fine). I've read the hub bore is bigger on the FR-S(56mm), so the OEM wheels wouldn't fit unless you get the center bore machined to fit the FR-S.

^He has a thread made actually.

just looked it up... Im jelly lol

^I'm not lol. Car has no rear passenger space at all, the seats are rather useless, should have made it a 2 seater. Other than that though all else seems good.

^^That's my biggest gripe with the car.
