New wheels.
I was thinking about getting the wheels below for my 93 z28, but if I read the faq above correctly I need a least a 38 offset. These have a 35. I was just curious if anyone knew if these would work. BTW the ones I was looking at were the 17x9.

If I understand the question, you are asking if you can run 35mm offset 9.0" wide wheels. You appear to feel that the FAQ indicates you should not go less than 38mm.
If that is the qustion, do not "reem" anything. Opening up the rear wheel hub holes by lightly sanding or grinding the inside diameter is the solution to using newer GM wheels on a 96 or earlier 4th Gen, but that is not the question that was asked.
First, where in the FAQ did you determine that a 9.0" wide wheel requires a 38mm offset? Here's what the FAQ says:
The intent of the FAQ is to tell you roughly how far the wheels will push out toward the outside of the fender. The calculation is based on having the front wheel stick out about 1" more than the stock 8.0" wide 55mm offset wheels. If you go smaller on the offset, the wheel/tire moves more toward the outside of the fener. Make the offset too small, and the wheel/tire is outside of the fender. Some people like that look, others don't. It also increases the chances of the tires rubbing on the inner fender liners when the wheels are turned.
These are "guidelines", not absolute numbers. comparing a 35mm offset to a 42mm offset means the wheel/tire moves another 1/4" toward the outside of the fender. But it will not stick out as much as the photos of the 25mm offset 9.0" wide wheels shown in the link included in the FAQ.
In any case... do NOT "reem" anything. It will not solve an offset problem.

9.0":
Tire edge outside fender = +25mm
Tire edge slightly inside fender = +42mm
Tire edge matches stock SS/WS6 wheel = +50mm
The 25mm offset 9" wide wheels puts the outside edge of the tire slightly outside the front fender. The plastic fender liners will have to be modified to eliminate rubbing. Many are willing to have the tire outside the fender, to get a wider "lip" on the wheel. Here's a link to a thread showing an example of these wheels:
