i'm going to buy some draglites for my 90GT and i was wondering what would be a good size rim and what backspacing would i need to get?

i went with a 15x8 in the rear and 15x3 1/2 up front. i wanna say ive got a 5 1/2 in. backspacing. they tuck in the fender real nice. im happy with them. i stuffed them with a 275/50/15 nitto drag
turned out lookin pretty sweet. any other Q's, shoot!

alright, didn't want to sound dumb but what is backspacing? i'm also getting lakewood 90/10 in front and 50/50 in rear with some eibach drag launch springs don't know if that would make a difference in what backspacing to use.

Nope that won't make it difference in your back spacing.

Back spacing is the distance from the rear lip of the rim to the back of the centre of the rim. Take a flat piece of whatever, put it across the back of the rim and measure from the piece of wood or metal down to the back of the rim.

hopefully that explains it.

I've got a 15x8 with a 5.5" backspacing on my 89. I run 275/50-15's M/T DR's on my Draglites.
