Lug nuts

[gp02a0083]

ok, im just curious with the offset washers, the rim holes on mine are kinda oblong, thought using the offset washer would be ok. And why the hell do they sell these in packs of 4?! not i have to buy 3 packs just for the rear

I'm not sure what the offset washers do... so you might be right, they might be better for your wheels.
... they sell them in 4s because most tuner market uses 4 per wheel. And alot of people use the 5 as a lock nut... So to make it universal for everyone, and for their logistics, most lugnut manufacturers package them in 4s now.
