back spacing ?????'s
 

ok well i am to the point where i am ready to purchase my new wheels......but i installed the classic performance products 4 wheel disc brake conversion kit, when i called the company, they couldn't tell me what kind of back spacing is recommended.. does anyone have this kit?? since i am still stripped down tot the frame, i can't figure out how i should go about measuring for the backspaing. if anyone can offer some help i would greatly appreciate it.and again thanks!!

oh i am planning on running either 20's all around or 18's and 20's if this makes a difference??

nobody has a four wheel disc brake conversion here?? c'mon fellas i need some help here, ya'll are normally good at this stuff......

...what exactly do you mean by backspacing?

I don't have rear disk brakes, but my rear wheels are 18x9.5's with 5.25" backspacing. The fronts are18x8's with 4.5" backspacing.
