I'm looking at these wheels for my Blazer.

What will the offset on these do? I've been looking for months for rims on eBay Craigslist Internet and I can't find any i like more than these even ones in my city for cheap on craigslist. Found plenty of camaro wheels but then I would have to get spacers for the new ones or 2 for the old ones since they are 2 different bs. Well enough rambling. Can someone help with this? Will both work?

Those rims will stick out 3.25" further than the stock rims on your 4x4. You definitely do not need spacers. Depending on what tires you pick, and what you have for lift you'll likely need to do a decent amount of fender trimming to avoid rubbing all the time on corners.

Not sure what you mean by needing spacers for Camaro wheels. Any Camaro wheel up to about 2000 will be a direct fit, and will move the tire 1.5" farther out (4.5" backspacing on older Camaro wheels). The 2001-2004 Camaro's still had the 4.75x5 bolt pattern but had 6.8" of backspacing. The newer Camaro wheels (2006ish? and up) have a slightly different bolt pattern and will need adapters to fit properly. Is this what you're talking about?

I'm talking about the 93 and up camaro wheels. They are 6.875 BS.

These are the wheels I ended up getting.

Putting some firestone 265/75r16 on them.

Those look nice on a blazer as they are still a GM product. There are a greater selection of 16 in tires than 15.
I had a prior series IROC on my 2dr.
