All of the reviews I've read about Dinan suspension mods indicate that they get this kind of thing right, in some cases with test data to back it up in terms of lap times and that kind of thing.
Why spend the money on an //M to then screw up one of the best parts of the car: the handling set-up. To just add an agressive drop screws it all up. To change one thing, requires changing many things, and changing them very carefully and with lots of understanding of how every little difference affects every part. Not easy, and certainly not simple.
