Ok here's the set-up. 2003 Silverado ECSB. In the future I plan to do a 2/4 drop. I found some wheels that are 20x10 and I want to know what backspacing I need so that it will look good. The wheels are available in two backspacings: 6.48 with a 25 offset and 6.72 with a 31 offset. Which ones do I need to get?

Thanks
Chris

 

get the ones with 31 offset

 

What size tires you planning on running?
