I have driven a few LP's with the spring conversion kit, and have found it to be awful. As well as losing the height adjustment, the ride is very poor, jarring at low speeds and un-acceptably floatly when driving at high speed. Also when cornering a small mid corner bump is enough to send the entire vehicle into a series of side to side rocking movements all the way through the rest of the corner. The spring conversion would be acceptable if the coils could match the variable rate of the airbags. Yes the airbag system can be expensive to fix if it fails, but the superior body control is almost worth the hassle.
