Like was said you'll need to go 11 mm minimum.
Have you measured the actual backspace?
That is with steel rims that have a thinner cross section between the tire bead and edge of rim where traditional weights clip on.
Is what part of the UCA is hittiing what part of the rim?
Is it hitting at ride hieght or just when jacked up?
The inside lip is hitting the ball joint.
I haven't measured the actual backspace yet (I assumed that the +10mm/4.9" backspace was accurate. In any case, it seems hopeless without either drop spindles (which almost everyone says aren't a good idea) or having the front wheels narrowed. Unfortunately there seems to be only one place that does this and they have a 4 week lead time, it costs $150/wheel, they're 600+ miles away from me so I'd also have to ship them...and in the end, I'd be running a narrower wheel.
that's a big expense for a preferred style of wheel.
The wheels themselves are Rota RKR. They're RS Wantanabe knockoffs... not everyone will dig them on a 70s American coupe but I love them.
The help is appreciated just the same.
