S55 (more power, more robust engine, higher redline, closed deck)

New exhaust system
Chassis stiffening (carbon strutbrace, bulkhead brace)
Spring/damper tuning (lowered ride height 5mm)
Ball joint suspension
Electronic steering retuning
Stability control retuning
M1/M2 programmable buttons
Upgraded brakes (yes...an option)
if it has programmable buttons you would have to assume that the settings can be changed independently across engine, steering, suspension etc.

That would be a big upgrade.
