mods

I just got a 2002 Chevy S-10 and I’m looking for stuff to upgrade it, it’s fairly stock I don’t really know what’s been done but when I look it doesn’t look like anything has been done. What would be the best thing to do to it? And what’re some good websites to use to find aftermarket parts

I have a 2002 GMC Sonoma. I'm interested in dropping it 3-4" what rim's would look good? I'm looking for a staggered look. Also what's a good suspension set-up to drop it? (The truck is completely stock. SLS 2WD Extended cab.)
