Not enough back spacing on the back wheels. I would need to narrow rear axle 2 inches, and maybe move shock mounts etc.....(to many other projects right now) I have looked for other 17"X10 1/2 wheels with more offset and no luck.
Phil,
What is involved in doing a “315 Mod” for FFR Mk I and II roadsters in order to get 10.5” wheels to fit?

Not really sure of the entire process. I think it can be done if you narrow your axle (live axle) 3 inches and remove quad shock. Independent rear?????? I may attempt in the future, but to many projects right now.

I don't have the exact detail but you basically need to grind off some of the square tubes in the footwell, grind the shock tower and move the aluminum panel in the trunk.

That's why I decided to stay with 275 tires when I switched from 17" to 15" on my MK2.

For those following the post. The 315 tire, 10.5" wheel mod is finished (FFR MKI). I cut down the rear axle tubes 11/2" on the passenger side and 1" on the drivers side. (my rear axle was always off 1/2 inch, a very common FFR MKI issue) each side and used new Moser axles made to my specs. The axle cut is totally dictated by wheel backspacing and offset. The 2X3 steel tube that is under the trunk was cut flush to the trunk aluminum. I cut out the "stock" mustang shock tubes and installed Viking dual adjustable coil-overs behind the axle. Eliminated the quad shocks, moved calipers from 10 o'clock position to 2 o'clock, rerouted brake lines, E-cables etc...… I have about 1/8th" tire clearance inboard and outboard. After a few short test runs, no rubbing or strange sounds. I am waiting for warm weather to get a good heat cycle on the tires before I really give it a good test.
