1. Anybody running a 15x10 rim for drag radials? I was pretty set on these Cragar Soft 8 Chrome Wheels 3985160 - Free Shipping on Orders Over $99 at Summit Racing but I am worried the -38MM offset is going to push them out way to far. I don't mind if they stick out a little but I don't want it to look goofy lol. I was going to run the stock chrome 17"s up front to match as a drag setup.

2. Where can I find some center caps to fit the decladed GMC rims? I rather not silicone in the stock ones from the cladding.

 

Get your differential narrowed. You're lookin at under $200 plus about $350 for shorter axles made to spec. Not bad at all and no worries on them sticking out.
