2013 C250 performance options ?
Upgraded brakes, sway bars and using something like Michelin pilot super sport tires would help with something like track times.
You can get an add on box that tricks the ECU's sensor inputs for a little extra power. But would likely cause CELs and limp mode.
Without the availability of any ECU flashes for this platform bolt-ons would be pointless.
Michelin Pilot Super Sports is a good start.
