mk with the de-deion rear end fireblade power.

its been suggested that 275 up front
and 175 rear.

also the shocks are different lenghts
should the shorter ones go at the front ?

My car is a Stuart Taylor chassis with a car engine and an Escort live axle but I have similar spring rates to you.

Front; 275

Rear; 150

I also have the shorter damper (AVOs) on the front axle.

I'd take a starting guess at between 250 and 275 on the front and 140 ish on the rear, with a bike engine.

Has anyone measured there wheel rate. As in 200 lbs on the front of the car drops in 1 inch so 200/2wheels = 100 lbs /inch per side.
