heh. so i gather one is saying 18's is going to void warranty?

WRONG! dum fuk.

18's are rims, rims are rims whether 13" to 22" they are just RIMS! they absolutely canNOT void the warranty. Its like saying putting performance tires on stock 15's is voiding warranty. Its just plain bullshit.

its like what str8acura said. nothing can void the warranty unless proven that it caused the problem.
