Hey all, I'm looking at getting some soft 8's from SummitRacing. I'm new to all this rim sizing and backspacing, etc. I don't know a lot about lug nuts but is it going to make a difference which one of these i get?

I'm looking at getting the black powder-coated soft 8's 15x7 with a 4.25in backspacing.

While I'm at it I might as well make sure these are the right center caps for these wheels.

Thanks in advance.

 

The Cragar's for our trucks are going to use push through center caps in the 3.3" size, so that looks right.

As for lug nuts your going to want 12mm x 1.50 RH, and for use with the Cragar rims they will need to be 60 degree conical seat nuts.

I personally went with the gorilla caps and lugs in the appropriate sizes for the all black look.

As for your backspacing that is kinda up to you. Not knowing what tires your planning on putting on them I cant really speak to the wheels themselves; I have 4"bs cragar 15x8 and they stick out oh just a wee bit!

 

Okay so either set of lugs will work?
