Took my "in progress" v8 conversion out for a spin the other day. 4.0 liter aluminum v8 from Range Rover. Ran strong but stock suspension was very spongy. Felt like driving mom's Buick. What have you done to retain the wonderful stiffness and handling of the original 914?

Hey Streetrover,

I'll bet my direct answer to your question will make fur fly:

Assuming 22mm front torsions bars + swaybar, I would recommend 250 - 300 lb springs to balance the chassis. Neither of these rates will make your ride harsh.
I've been driving my car to the track with 400 lb springs and not been uncomfortable.

FYI: The actual WHEEL rate at the rear is 1.17 X the spring rate due to where the spring attaches to the swing-arm.

As I stated before, soft rear springs will give a bad understeer. Sure it's safe, but you won't be able to turn-in to a corner, so forget a spirited drive in the canyons.

Best,

Terry
