i was just wondering if i can use aftermarket lugnuts on my OEM BBS wheels on my '08 sti? thinking Rays or something similar. i know that there's issues with fitment, see:

I too have been using the McGard spline drive lugs on both me OEM and aftermarket wheels. It works just fine.
Yes, I have been using them since I got the car, they work fine.
When I was buying wheels from Fikse,I sent them a stock nut,a Subaru/McGard locknut,and a McGard spline-drive nut. Fikse told me that all three had the same correct cone seats and could be used interchangeably
Yes.
Subaru uses a M12x1.25 nut with 60º cone seat just like aftermarket tuner wheels. The face that meets the wheel is a bit smaller then aftermarket nuts, but all else is the same.
I've been running black McGard spline drives on both my OEM BBS set as well as my SSR winter set essentially since I got the car. The McGards are nicely made with a two piece design - the cone seat doesn't rotate with the rest of your nut as you torque down. So far the black finish has survived two midwest winters with nary a tarnish to be found.
OEM Subaru lugs (at least the locking ones) are also made by McGard if that means anything to you.
Go to the The Lug Shack for decent selection & prices.
Would this hold true for '08+ OEM STi 5-spokes? Due to an unforeseen OEM lug nut shortage, I would like to use my McGard spline drive nuts until the replacement OEMs arrive.You really have the option of stock or Mcgard. Our lugs have the 60 Degree taper or conical seat. but the factory BBS lugs have a shorter seat length. Our thread pitch is 12x1.25. McGards are very nice and are high quality also. They are available in gold, black, chrome and they also make the custom sti logo lugs. They offer several layers of theft prevention as they are spine driven and are available with locks. They also have the spinning seat which helps to not scratch your wheels. I purchased mine from the lugshack.com. They have great prices and fast shipping.
gold mcgards
Chrome Mcgards
Missed that thread--thanks. Yep, this is exactly what would have happened with those on (scary!!!) :KICS have a different taper, cannot use those on oem wheels. Only aftermarket!!! Stick with OEM or MCGARDS please. OR your wheels will fall off.

So, just to make sure before I order....these are the only black lug nuts w/ locks that will fit my OEM BBS Wheels for an 07 STi? They are McGard....

+1 for the McGuards... I have them on both of my cars. They fit great, offer great theft protection and look great as well! Couldn't be happier, and I also got both sets from lugshack.com![]()
To be completely safe, Id only run the OEM or Mcgards on an OEM wheel no matter the brand.
The issue is the seating of the lug to the wheel. Moteki lugs are going to have the same taper as any tuner lug.
