will 15" welds fit over rear calipers on a 93 z28 say a 15x10 pro star for instance also will the 15x3.5 wheels fit the front with or without spacers, another question is what is the best 15x10 backspacing to go with?on a camaro thanks for your assistance with this.

 

For the Weld Pro-Stars or DragLites:

In the front, you need a 5/16" spacer. You might be able to get by with one slightly thinner.

In the back you need to grind the fins off the caliper. Correct backspace for the 15x10 is 7.5". You won't find that backspace listed in most places... Summit or JEG's.... but you can get the part # off the Weld website and order it through them.

You will also need longer wheel studs front and back to pass NHRA tech.

If you are talking about the "XP" series, you won't have any of the above problems.
