If you're looking for light cheap set of 17's for the track
Factory Aluminum 17"x8" take offs are found on Kijiji for dirt cheap,
and only 24 pounds
pair those up with some 275/50R17 DR's (27.8" tall) and your all set.
I drop 4-5 tenths when I take off my 95lb Grapplers on stock 20's
and put on my 17's with 295/45R17 Sticky Mickey ET's
