[flyingdutchman]

hey got a 99 2wd standard cab im planning on giving it a 5/5 drop or 5/6 drop now my question is i want to order daimond racing rims 17x8's...or mustang saleen style rims with lip from american muscle.com but before i do i would really appreciate it if some one can tell me the offset(backspace) or size of the spacer ima need to make the rims flush with the fenders and the rear. i am going to be runiing stretched tires. im going more for a drift/street look or hellaflush look. please someone help me im going crazy here trying to find the perfect fit! ( just incase anyone doesnt know what hellaflush is heres the website that might help hellaflush.com)

also if anyone else has done this i would like to see some pics of some street trucks with some nice fitment..that would help big time and give me some ideas thanx!!
