I'd like a set of 18x9 GTA rims, but I probably would not be able to afford them.
I pulled a front bar off a 1989 IROC Camaro. It must weight 30 pounds, but it cost about $10. The hardest part was shaving the urethane bushings down so they fit into the G-body shells. Then I stripped the threads in the frame rails when trying to mount the beast. But the bar itself required zero mods. I just wire brushed the scale and sanded the bar smooth and hit it with Chassis Black.
I like POR-15. Does require several coats, comes out really glossy, and needs a UV-proof top coat. But you can see the first coat actually turn flat when it reacts with the oxide or the fresh blasted steel. I recommend Metal Prep (or maybe it's Metal Ready) to treat the blasted steel before you paint. And be generous with the wire brush and compressed air to get all the sand out of the nooks and crannies.
Don't forget - set your end link length to be in mid-plane so nothing collides if you bottom out or let the light shine under your tires.
