Backspace double check
 
Beatin the horse one more time... something is not right with my setup.

i bought cragar soft 8 series off jegs.com
jegs.com

Soft 8 397 Series Wheel
Size: 16'' x 8''
Bolt Circle: 5 x 135mm
Rear Spacing: 5''

does this mean that they really are suppose to have 3" backspacing or did they just confused me with adding "rear" to that? even so, why did my wheel measure out to be smack dab in the middle? meaning 4" no matter what crooked way i tried to think they meant by rear backspacing.

i believe fabtech 6" requires 4 5/8" backspacing. which means 4 5/8" in from the front of the wheel to the mounting plate. correct? which in my pea pickin mind means a wheel with 5" backspace should set the tire away from the body/suspension of the truck than 4 or 4 5/8" correct?

im rambling, im tired. hopefully someone can help me a lil.:bows:

I think it was probably a typo and should have read backspacing.
Also, this is how you measure backspacing.

Backspacing... back of the wheel to the hub face. If they require 4 5/8" backspacing maximum, 5" would not work. If your backspacing really measures 4", you should be fine.

had issues with the tire rubbing on the tie rod end tho with these wheels so i thought maybe something was up. my only thought is maybe its cause theyre 8" wide instead of 10" with 4 5/8 bs like they mention

thanks for clearing up my question guys.

The nice part of working with backspacing is that the wheel width makes no difference. No matter how wide the wheel, 5" backspacing is always the same.
