Re: 1967 Mustang Coupe Build (Electra)

All right! Shelby drop!

My "GT" springs sit my car too low with the Shelby drop. I ordered a new set of "stock height progressive rate springs" from SD, but initial uncompressed measurements are really similar to the GT spring (my stock height springs were a couple inches taller uncompressed). If they still sit too low, Street or Track (and others) recommend moving the spring perch out 1" on the A arm. This is supposed to further improve geometry and should raise the car 1/2".

My last resort is that from what I understand 67/68 springs are exactly the same as 65/66, just longer, so I'd buy a set of 67-68 springs and cut them.
