I found a good deal on a 12 bolt from a 3rd gen as well, And was wondering the back spacing for a 8 inch wide wheel to fit under the wheel wells and not stick out at ALL on my 98 Z28?
Also if I chose to use a 10 inch wide wheel for the track, What should the back spacing be??
Any Help?
Thanks in advance!
James

my question relating to this is...... i have 305-35-18s on 10.5"x18" Z06 wheels on my '01 Z w/ 10 bolt, does anybody know the spacing on these, i will probably go with a 3rd gen rear b/c i have also seen several good deals on them, i knew they would bolt in and that they were narrower, but didnt know how much, i'm changing to 15s all around, the wheels i want are only available with dish, just need to find out how much b.space i need so they will clear the same as the 18s......... any help is greatly appreciated
i run a 28x12.50 with 6.5bs on a 15x10 rim. the "typical" thirdgen spacing would be 5.5bs but i wanted to hack out my wheelhousing to tuck the slicks even more.
I put a 4th gen on my thirdgen and its about 3.5-3.625" wider OVERALL which means 1.75 or so wider per side
My car has a broken 10 bolt in it (12 bolt going in wifes car) and its about that much shorter, I put my third ged BS rear wheels back on and there is no was I was going to take it off the jacks haha.

car looks a lot better with a real set of tires in the back steve, no more mud boggs, lol.
Well i ended up getting a midwest fab9 stock width, works out perfect for me
nice i also have a set of 28x11.50 ET drags i'm going to try out as well if I don't sell them. Those mud bogs were sweet on the street with the spool though. I took the slick pics way back with mike when we put over 50 miles on the car that one day for our photo shoot.
I have a 9" (3rd gen width) that I'm putting in my 4th gen, I didn't want all the backspacing that the 4th gen rear has. Couldn't beat the price either.
