Coil Springs

Does anyone know the difference in the front springs sold for a regular towncar and a signature towncar?

which handles or rides better?

i have a signature, and the coil springs have a different part number than the regular towncar. i thought this was odd, but according to my goodyear shop, my regular mechanic and discountautoparts.com there is a difference. wonder what that is?

hmm I never noticed a difference, but by the time I get them the springs are usualy pretty soft anyway. One is most likely a little more firm, but either one can be used.
