Front tires do not fit within the wheel wells-need help.

Larry,
I am using a modified brake assembly that uses the mustang II spindle with a bracket that adapts a GM caliper. This was a great idea 20 years ago. I do not believe that this is pushing the wheel out though.

Did you get to the Gregory Car show today? Quite a crowd.

Tom,

Here are a few pics of the suspension from underneath and the pin drive adapter from the rear wheel (same as front).

I didn't make it there today. My dad was having an outpatient procedure and I needed to be there to take him and pick him up. My brother was there though with his FFR Daytona.

I stopped and talked with one of the guys at the show about my tire issue and asked him if it was your brother's Daytona. You had told me about it when you let me borrow your tires some time back. Quite the car. Mine has been on the road a few times but I need to resolve this tire problem and then get it painted. Soon enough.

mjhcobra,

Nice thin pin drive adapter.

Can't make out from the picture how close the strut rod or the end of the upper a-arm is to the rim.

Mine are 17" wheels so the upper a-arm isn't an issue.

You could probably measure how far in the wheel rim could go and maybe borrow one to try?

If you won at poker last night maybe this would help: Wheelrite - Wheel & Tire Simulator by Percy's High Performance, Percy's Performance, PCY-01201

Seems like you could also make one out of some scrap material. The most important part of that would be the rim; the tires will probably(?) clear.

BTW, is that a split in the upper ball joint boot? Or just a mark that the camera picked up?

Very cool tool for wheel offsets, I have not seen that before. There is about 3" between the tire and the strut so I am good here. And yes, the boot is split because it was installed in 1993. This has been a long project with lots of breaks for kid reasons. I even have a freeze plug leaking it has been so long. I am using 78 Granada rotors, but the inboard side of the rotor is about a 1/4" from the lower control arm so I doubt the rotor/brake set up is the issue. I reviewed the EM manual again it says to use a 15x7 wheel with 3 7/8" back spacing and a 235/60 15 tire. I currently have a 15x7 wheel with 3" back spacing, a 245/60 15 tire and a 3/8" pin drive plate. This could be the majority of my issue.
I could get new wheels with the correct back spacing to start and then consider shorter A arms or a tire size drop.
