so i'm buying D Cepek FC-II with moto metal 18x9 but not sure which size to get. the tires are 12.9in wide even though they say 12.5....i dont want them to stick to far out but dont want rubbing which set up would be better????
#1
backspacing= 4.53 offset= -12mm
#2
backspacing=5.71 offset= 18mm
#3
backspacing= 6.18 offset= 30mm

Your help would greatly be appreciated and photos if you have any.

 

+18 would be my vote. I have -12mm and my 12.4" tires stick out a good 2 inches. I get quite a few rocks thrown up from my tires. Pics in my gallery.

 

thanks i'll look into them then but i do think your set up looks great it's not to far out

 

A 9 inch wide wheel with 4.53 inches of BS will stick out about 2.5 inches farther than the stock wheels, 5.71 inches of BS will stick out about 1.21 inches farther than stock and 6.1 inches of BS will stick out about an inch farther than stock.

 

Since you have stock rims and tires.....

The tires alone with stick out roughly 1.5'' further than stock
Add the 1.5'' more for the width of the rims regardless of backspacing
I would go with the the 5.71 bs.

I am assuming you are leveling and going with 33's?

 

yes i have a 3in leveling kit with 1in add leaf

 

I have 5.71 +18 and I think they are perfect.

 

Also, don't go over 2.5 inches with a leveling kit. The 3 inch kits leave the ball joints at too severe of an angle to last.
