I see that SuperPro offers two different polyurethane collar thicknesses for the cushion pieces that go on the top and bottom of the front road springs. The options are .120" and .325". I can't find a further explanation on any of the sites. Does anyone have experience with these? Is it merely ride height - the difference being .410", if you went with two thicker pieces?

Hello
From my experience the thicker ones were used on TR2-4 and the other used on TR4A-6 after the suspension was changed.

I do not think that would be much of a change ride height I only found one book that addressed front springs. ( Leyland TR Competition manual ) It stated competition springs were shorter and heavier but did not say by how much but were left hand coil as to stock right hand coil. Thinner would be best bet.
