Those of you that have increased the spring rates on their birds what if anything have you done to the rear springs? It seems as an upgrade should be in order for the rear also.
I note the springs for 57 fords and 59-60 Tbird will fit. 57 wagons have a higher rate,100#/in (Tbird) to 165 to possibly 195#/in for station wagons. 59 to 60 Tbirds have a 6 leaf spring but I have not been able to determine the rate. It seens as if there is a desireable ratio inthe front to rear spring rates. Any input?
