Hey Everyone, long time lurker. I just picked up a 65 Fastback to go with my 86 GT. First mod is to ditch the 14 inch styled steels (which will be for sale cheap soon BTW) for some 17" vintage wheel works V45s.

Here is my question: I've read EVERY post on this forum and others where people have asked about 17's on a 65/66. It comes down whether you want 17x7's in the front with 3.75" back spacing OR 17x8's with 4.75" backspacing. The car has the "shelby mod" control arms. I know there isn't much room and I don't want any rubbing issues. CJ Pony Parts offers the following package:

17"x7" & 17"x8"
3.75" & 4.50"
235/45/17 & 245/45/17

Anyone see any issues with that? Any reason why I'd want to run 8" rims in the front or be better off with 4.75 backspacing in the rear? The package seems to be a great deal with tires.

Thanks in advance!

Thx- seen the chart. Looking for "been there, done it" feedback. Many people do things their own way.

I could be wrong, but I think this is more of a personal preference question than what will fit. I have a 65 Comet that I want to put 17s on, and from what Ive seen and read a 235 on 8" rim will just fit. The 235/7" may give you some more breathing room in front, but I would say if both fit, go with the bigger set.

If it were me....I would run 235 45 17 all around. You aren't going to gain much with the 245 in the rear versus the 235.

If you run -1 degree on the alignment with the 17x8 4.75 with your shelby mod and an adjustable strut rod you should be able to run them in the front without even rolling your fender.

Ohh and I have a chart too....except its a been there done that chart made from lotsa people telling me what worked on their own cars

depending on how low your car is the front tire size might change.I cantr use anything wider then a 215, maybe 225 at the most.

17" x 8" w/ 4 1/2" b.s. on all fours...
245/50 out back and 225/50 up front. on my 65 fastback.

I'm also running '07-up Mustang Steve front disc conversion and '00 Crown Vic rear disc.

without an engine/tranny/interior in mine, when I've roll the car around in the garage the fronts do have a very slight rub at full turn on the stops.
.
but DAYUM...does it look sweet with all that rubber on the ground!!

17x8, 4.75"bs with Nitto NT555 235/45's on all fours on my '66. There's more room in back; but I wanted to be able to rotate tires, and the marginal gain in rubber wasn't going to make a difference in traction.
