  • Weld Draglites... help

    Getting some draglites TODAY. I need to know what to get as far as backspacing. What IS backspacing anyway? I know they come in 3.5", 4.5", and 5.5". The rims that my drag radials are on now stick WAY out and they have 3.5" (I think). My fenders rub the tire when I take a hard turn or hit a bump. I don't want them to stick out so much. Do I need more or less? Someone help me, I'm clueless.


    Thanks =)

    Ok... I ordered them with 5.5" backspacing. I hope that's what I needed.

      You did good. Sorry about not answering until you already ordered, I just saw the post today. This is some information for you on backspacing anyway, for future reference...

      Backspacing measures how much the mounting surface sets back from the inner edge of the wheel. Imagine laying the wheel face down, with the inside facing up. Now lay a yardstick across the wheel. Now drop a tape measure from the middle of the yardstick, straight down to the part of the wheel that goes up against the axle/rotors. That's backspacing.

      So, if you have 3.5 now, if you are putting the wheel on, as soon as the inside edge of the wheel passes the lug bolts, you push the wheel 3.5 inches more before it touches. With 4.5, you push the wheel another inch inside before it touches.

            Actually, according to the diagram at the link that Dom posted, backspacing is measured off the centerline of the wheel, not the inner edge like I originally said... It had been a while since I had looked into this, and I was going from memory. Same concept, just a different measuring point.

            Hope they work like you want!
