Thanks for the feedback!!!
FYI Been driving the car for two weeks now with the new springs. There are two H&R spring kits for the 300E. This was the milder of the two and droped the car almost 2" in front and 1.5" in the rear. The wire diameter was the exact same as the old springs but there are fewer windings. Ride is a bit harsher and large pot holes are now uncomfortable. Would have prefered the same soft ride as I have other cars for performance (66 Shelby being set up for the track and a 65 k-code w/16's, koni's and lower 4"). Would like to find some 8-hole 15's off a 91 to 94(?).
Thanks again for the info everyone!
