Who cares what color they are ? Once they're in the car you can't see
them anyways. They look like a nice product, and the company sounds
reputable. (they refer racers to use other brands)

I need to dig up some old tech school notes. I had all the formulas for determining spring rate based on the amount of coils, diameter of the spring and the diameter of the coil itself, minus that and times that.

Just my two cents on the subject...

Progressive rate springs were originally designed for cars like Cadillacs and Buicks. It is a spring that will hold up the car without being too soft or too harsh. They are not a good performance spring. They are a comfort type of spring, so they *may* have stated that they were for T Types on the assumption that T Types are not a performance car like the GN.

Natty, I have all those formulas as well if you need them.
