cmanf, If you are using late model Bullits you will need to use either 1 or 1-1/4 inch spacers to clear the undercarriage. I used 1-1/4 on my 16's.
Thanks! I thought I would have to use a spacer with those either way. I like the Bullets but it may be temporary. I should be @ the 500-600 hp @ the rear wheels
Dont know if the spacer will hold up to that kinda power. I found other wheels I'll have to get down the road they arent cheap.
