Maybe I was not clear. I test the suspension movement to verify nothing is binding without a shock or spring in place.(no wheel / tire attached to the hub)
That is also a good time to adjust the bump stops to make sure the suspension is not hanging on the shock when in rebound and the suspension is not bottoming out the shock on compression.
Do you have spherical or poly busing on your shocks.? Due to the upper and lower control arms swing in different arcs, I often see binding or shock body / coil spring interference with the poly ends.
I would suggest double adjustable shocks for most drag racing....for those that want suspension travel, the double adjustable makes it easier to adjust the suspension for little resistance when for rise when accelerating and keep it there so it doesn't have the pogo effect. Coil over or not.
Single adjustable for a street car for ease and affordability.
The big question is....What is the compressed length of your 10" coil spring at your desired ride height...with the car on the ground and all the weight on it?
