After doing much research, I found that swift springs were the best for the q50. Swift not only cares about how the car would look, but also they want to maintain the integrity of the ride performance. Although a 1in drop in the front and a .6 drop in the rear may not seem much, it makes the stance of the car look so perfect. Unlike other companies, swifts does it's r&d on US cars when others may test in foreign countries where the cars are lighter and may have different spring rates, (Due to regulations) overall the car is not bouncy, it does not rub on my 20in niche wheels, nor does it ever bottom out. The ride is so smooth that my wife who hates riding in my modified cars complemented on how smooth of a ride it is.
