My wife wants Torq Thrust II's on her 65 fastback and I need to know if 16x8's will fit in back with 245x50r16 tires and 4 7/8's of backspacing. I also want to run 16x7's up front with 4 inches of backspacing and 225x50's. Has anyone done this or know if they will fit?

The 16X8's will fit. The 4 3/4 backspacing may hit the leaf spring or the upper
wheel house.
I have 16X8 on my '65 and they fit with the lip rolled and
I do have 245/45/16's. I also have 16X8 on the front with 225/50/16. Both
front and back on mine are 4.5 backspacing. One report I read said that
215 or 225 was the bigest you could put on without rolling the lip.

I have 16x8 with 4.5 backspace, I have room for 245/50 on the rear, but I didnt like how tight things were
with 225/50 on the front so will get 205/55 and a 16x7 with 4.25 backspace on the front. I havent rolled
my fender lips, but I have 5 leaf springs and car is only lowered an inch all around right now and it seems
okay. still working on exhaust, so dont have any miles on this set-up yet. by the way, I have magnum 500
in the 16 inch size, I really like them!! pretty sharp, hope to start putting pictures up soon.

Have you made any changes to the brakes? Are you planning any brake upgrades in the future? If so, do the brake changes first as many non-stock brakes change the backspace required...Ask me how I know /forums/images/icons/shocked.gif

If your brakes and suspension are stock or near stock, and you're building a cruiser (vs a racer), a sweet combo would be:

16 x 7 4.25 backspace

16 x 8 4.5 backspace
225/50-16 or 225/55-16 for a little "rake" (taller tire)

You shouldn't need anything special suspension-wise, and you shouldn't have to roll the fender lips for the above combo. (Disclaimer: YMMV, every car is a little different!)

If you plan on having a little more fun:

16 x 8 4.5 backspace

16 x 8 4.75 backspace

This combo will require rolling the rear lips, and a negative wedge kit or tubular a-arms up front.
