What backspacing needed for 15x8 wheels?

[zurud]

I am looking for some drag wheels. I look at summit and jegs. They have their own line and a lot cheaper than welds'. However their backspacing is in inches. I am used to like 38 backspacing. I really don't know what it really mean, inches or millimeter. On their site they list 4.0 and 4.5 inches of backspacing. I want to know if I can use any of those. I know some people here use weld wheels.

Thank you.

You need to get some with atleast a 5" backspacing. Alot of people run the 5.5" backspacing like I do, I have the weld prostars with 5.5" backspacing. I wish they were 5" though because they would be a little more flush. But there is a thread on here with more info on the wheels.

Those should work fine! I actually just found some really nice looking Wedsport wheels that I might get, they are lightweight and will fit good, even if I decide to upgrade my brakes. I can fit a 26x10.5x16 tires and be set! They only have a couple left, they are $199 each, I don't know about you but these I think would look much better. And they are only 14lbs.
