At least a 3.75 inch backspace is required. Anything over that is mor than enough. TRUST ME
By guessing
The Pontiac Firebird and Chevrolet Camaro from 1993-2002 have factory 16x8 inch wheels. 16x7 wheels will have to be custom fabricated to safely fit the unique backspacing and hub pattern of these cars.
Some companies that make test and measurement equipment include Freese Enterprises, Inc. (which makes custom test and measurement equipment). Another one is SKF, a major engineering company, also is another source for this type of test and measurement equipment.
5x4.5 should be
One down, four up
Yes. You need to find a company that makes a custom 15in. wheel that can provide a 8x170bolt pattern and less than 2in. backspacing to clear the rotors. you might have to grind down the rotors a bit but not enough for structural damage. As for the wheel its self you may need big flares cause the wheels are going to stick out very far due to the backing spacing and it is illegal in many places to run a wheel and tire that sticks out too far from the fender. Also custom wheels aren't going to be dot.
No. the thread pattern is NOT the same
I found a lot of pattern designers listed by doing a search for "custom pattern designer" in my search box. You could try that, or look in your local yellow pages for a custom designer. Another way is to look up "custom handbags" and find out who designed them. When I am asked to design a pattern or costume from a design concept, I generally charge between $100 - $200 an hour depending on how difficult it is, and what level of design they want (i.e. specific fabric match).
5x4.75 or 5x4 3/4 standard GM.
Yes it is i have ine and need to know that to get custom wheels
Number of lug holes, then measure center to center distance apart. A 5X110 is a 5 hole 110mm pattern
I went down to the local custom shop, he called up his dude and he said yes. He told me you don't have to worry about it hitting the well. hope this helps
