Both cost the same which is overall better(ride quality, performance, looks)?

Thats what I was guessing, I thought air ride will be too bouncy when lowered. How BA is the MM package, it doesnt come with control arms, the next package up does, but cost 2400, Ill prolly just add in the LCA, so how ba is the susp package, will I be very happy I spend 1500, and be able to tell a big difference, will it handle like high end cars? will it be money well spent?

Is HnR sport springs give good ride, is it jerkery or harsh,How much will it lower the car? ARE they better the Eibach sport springs? Or better than FMS B springs?
