if u do launches as far as drag racing, yes bc when u drop it all the way down it acts as a strut. basically the arnott system is concidered a strut bag. theres a bag sitting on a strut point blank. if not over inflated yes still acts like a regular suspension, u can adjust the stiffness of it with the bilstein 16 position adjustment knob. well ive had the system 4 about 4 years. and my only gripe is the wiring for itcould b a lil more simpler as far as how their wiring is not ease of install. i havent tried other systems but i like it so blam
