15x10 backspacing November 03, 2010, 10:47:08 AM does anybody know the right backspacing to put a 15x10 under an 88 tbird? i've got a deal on some 5.5's but i'm not sure if they're right.i'm using an 88 tc rear. Quote Selected
15x10 backspacing Reply #1 – November 03, 2010, 11:23:25 PM I'm pretty sure you'll need at least 6.5" of backspacing. I do believe its what the mustang owners run. I think 5.5" will have them sticking out too far. Quote Selected
