I've an '03 wrx, with '04 STi BBS wheels. The oem '03 lug-nuts were used for the wheel swap.
Since, it's been about... 3 months? ... i've had two of the 'caps' of the lug nuts pop off.
Is it possible that the lug-nuts are incorrect fitment for these wheels? (too deep, and putting pressure on the inside of the domed cap)
Tried searching, came up pretty empty handed.
