Little bit more info on those coil springs. I am running only two Jaguar coil-over springs in the back of my A model. Tin body duece chassis supra box and small block chev, not to heavy but not to light either. What I am trying to say is; With only two standard jag coilovers my rearend is still stiff! I am contemplating getting a rate change once I have bedded in all the suspension. (I also have the gas tank mounted in the rear.)

Good luck to you and welcome to CHR.

Andy.
