Awesome fitment perfect for all wheels
This made a difference on the new set of wheels per the +25 offset and the weight increase.
Installed these on my 13 Wrx. Well worth the money! Install was pretty straight forward. The extra length is nice for running slip on spacers.
These studs are made very well, but word of warning to anyone trying to replace these on a 15+ WRX, the rear e-brakes and covers don't give enough clearance unless you cut a good chunk out of the brake dust cover. Have a pro install them because doing this on your own is very difficult.
Much better than oem and have that extra length needed for certain applications!
