OK thanks gents, but what I want to know is matching a shock to a vehicle weight and it's spring.

If the car was 2100 pounds front weight instead of 1700, and the T-bar was 1.24 instead of 1.00,
would I still use a Koni Red or would I look for a truck shock, i.e. MORE damping ?

How do you match the shock to the T-bar ?
