Any info will be greatly appreciated, Thanks.
Also I read that tire height differences will disable ABS on f-body's...Will the proposed setup make this happen? (Im planning on using the Eagle F1 DS-G3's)

C6 replica's
18x10.5's +56 out back 7.94" backspacing
18x9.5's +56 for the front 7.45" backspacing
I don't mind using the BFH![Devil](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_devil.gif)
Does the backspacing matter since we know the offset?
This is all hypothetical since i don't have an f body again, yet.
Wheels confuse me.

Offset is the distance front the center line of the wheel to the backside of the lug mounting plate.
Backspace is the distance from the back surface of the wheel to the backside of the lug mounting plate.
The only unknown factor to calculate one from the other is the thickness of the rear mounting bead.
Yes wheels get confusing, that is why we are here to try to help.

I know there is a "range", but I prefer to be dead on if possible.
Thanks!

Looks real good- Any problem with the ABS with the different size F/R tires? I know its minimal, but there is a difference of what, about 1/4 inch?- just curious if you have encountered any problems?

Does anyone run 275/40-18s on their Camaro? I was on Goodyear's website, comparing GSD3 OD and widths. I noticed that my 245/50-16 have an OD of 25.7 inches, but 275/35-18s have an OD of 25.5 ??? THe 275/40-18 GSD#s have an OD of 25.7 inches. THat would lead me to believe that the 275/40-18 are a better (more comfortable) ride that the 35 series? not to mention that I was running a 3.42 gear with the 16 tires, but my new Moser 12 bolt has 3.73 gears, so I dont know what the RPM differences will be.

Still the 275/35-18 (25.6) has a smaller diameter than the 245/50-16 (25.7)? I mean its only .1 inch but that still surprised me. So a 275/40-18 (26.8) should be able to fit ok, right? My car is not dropped at all. I wanted to get wider wheels in the back, so I could use 295/35-18 (26.1) but I'm not sure how more more contact area I will get by doing so.
Also, If I went 295's in the back and 275 up front, are teh differences in OD enough to cause problems with the ABS? I've heard different diameter tires can cause false ABS inop errors.
