I am trying to figure what coils and shocks I will need to replace my existing coils and shocks on front suspension. Existing coils were heated to lower about 10years ago and are pretty shot. I am just not sure what size lowering coils I will need to replace my existing coils and keep close to the same ride height. Only 1 ring on the existing coils were heated so I am guessing that would be close to a 2" lowering coil? Any advice would be appreciated. For a 91 Mitsubishi Mighty Max standard cab 2.4l.
