Got it. I'd really like to have the ability to rotate, so I'd probably go with the 0 offsets all the way around. Are they worse than S-10 wheels with Blazer brakes as far as the track width difference? (I have Xtreme wheels, now)Here are some fitment rules for 16X8" GTA's:
1) Zero offset "Fronts" fit all around on most G-bodies. 225-245 in front, 255 in back. Wider tires might need some modding with zero offset "Fronts"s
2) If you have larger brakes in front - Blazer, BAER 12", B-body/1LE (LS1 12"/Corvette 12"/13" don't really fit) you want to run the F-body "Rear"s (+17 offset) in front as "Front"s in front need more inner fender mods than "Rear"s.
3) GTA's may need a shim spacer for some brakes (especially with new brake pads) because the caliper face can rub the wheel web.
4) With 1" wheel adapters, "Rear"s work perfect in back and should have enough frame room for a 275.
5) Running "Rear"s in front puts the inner rim lip close to the outer tie rod and some trimming of the tie rod may be needed.
6) running "Rear"s in front can result in some A-Arm to Wheel rub when turning at some ride heights if using tall upper ball joints. Tall lower BJ is no issue, trimming of the A-arm should fix the Tall Upper BJ issue. Check the full range of wheel motion with the spring out to check for rub.
Now, I just have to decide which I want. I really think these would look RAD

But the GTAs are timeless.
