You can get coilovers that have 2 way height adjustment. Most height adjustable coilovers have the adjustment using a perch the spring sits on. You can adjust this up/down, but it will change the spring stiffness. From memory, the more you comress the spring, the stiffer the spring will be. 2 way height adjustable coilovers also have the bottom part of the coilover able to screw up/down to adjust the height. This doesn't effect the spring loading.

I do not believe this to true.

most coilovers have a linear spring rate and shouldnt get "much" harder as u go lower...

the 2 way adjustment is to give more/optismise shock travel... (in the cente) and not for spring hardness

The more u are able to extend the shock rod the better.. that why race shocks have such a short bodies as this allows the shock piston to have sufficient travel. Its a great advancement how they have incorporated this theory into the current coilovers
