It all depends on if they are heavier than stock...because you can get 17s that are lighter than stock but expect to pay mucho money.
Otherwise yes you will lose some horsepower ... how much ????? who knows you'd have to dyno your car. Someone said 1 hp per 100 lbs but I dunno.
But you more than makes up for it in looks
Someone else might know.
BTW what are the rims you are looking at ? [ 05-09-2003, 12:28 PM: Message edited by: RicePowered ]
