Installed lowering springs a while back and the SR is currently at the dealership getting the SUM reset along with some other work. Its my understanding that the 4C suspension is ride height sensitive therefore with lowering springs the car increases the damping thinking that there is a huge weight. When I explained this to the service mgr he didn't know how to reset the 4C. Can someone out there explain the resetting process or maybe the TSB number to "reset" the SUM so I can explain it to the service technicians?
