IMO 17x8x4.5 and 18x10x5.5 would be ideal if they would make them for the 68 and later A bodies

That way you could use 245x45x17 and maybe even 255x45x17 front and 285x45x18 in the rear for a 27" height

I have 285x40x17 (26") on 17x10x5.5 and would like another inch back there.

As for tire sidewall height (diameter), I agree 26-27" dia is ideal. A 255/45R17 is 26.1" dia and is easy to come by and will fit even an early A-body, as I have on my '66 GTO as below. Here are Firestone Wide Ovals in that size: http://www.tirerack.com/tires/tires....omCompare1=yes Click on Specs to see the sizes.
These wheels are ROH ZR6's, which were the prototypes for the Impala SS. I used '69 Bonneville hubcap centers which fit perfectly in the ROH centercaps. Brakes are 13" Corvette C5 front and 4th gen F-body rear (same calipers as the C5 except they are a bolt-on to our rear axles). Wheels are 17x8.5 reverse-mount, which is what the YO Rally II's are, and caliper clearance is very tight.

Love that car dude! I remember it from the Hot Rod article. I still have the magazine around here someplace.

Those wheels look perfect. They look like they fit tight against the body and dont stick out. Very nice.

Hey Mario65,

In post #45 you said,

"FirebirdMI thanks for your work and time on this. I know we all are going to get alot of it. I really hope it works for you. I have been rediculously patient. I am getting the bug again. I dont want to spend 4k on wheels and tires if I think I can get a Rally II look to work.

Heres my current stance and look:

Heres the stance I and look I want. I would much rather have a Rally II wheel do it than aftermarket wheels.

Do you happen to know what those wheels/tire size are? I too like that look very much. Any ideas.

Just wondering.

Sorry I didn't get back,
Just saw the post.

"17x8 4-7/8 backspace on front and 17x11 5-1/2 backspace on rear. 245/45/17 and 315/35/17 bfg KDs . DSE mini tubbed

All DSE front end, coil over relocation, koni's, DSE UCA/LCA etc. Back is DSE 3" drop leaf w/offset shackle, so basically its lowered 3". No problem with front rubbing, I could pick it up another 1/2 inch but I like the stance."

Has anyone seen these with some 50 or 55 series tires on an A body yet?

I plan on running 50 series tires.

Also can I get away with running 255's up front and 275's out back. The suspension is pretty much stock, but I plan on changing that after I get an idea of what I can do and still fit the tires.
