A new addition to MSO's tuning operations, the newly-created MSO Defined division is effectively the entrypoint to McLaren modification.
Dealing specifically with the 650S and 625C, MSO Defined can add a full aerodynamic body kit, along with an optional carbon fibre rear diffuser, extended side intake 'blades', a lightweight carbon engine deck lid and carbon wing mirror stalks.
Inside you can opt for a range of carbon fibre trim accents, as well as extended carbon shift paddles and a Formula One inspired instrument panel with sequential shift lights.
If you want to get more creative, the existing MSO Bespoke division can give you an almost limitless choice of paint, upholstery and trim options.
Since the arrival of the 650S, around 20 percent of McLarens built have passed through MSO Bespoke's hands - along with 95 percent of McLaren P1s.
MSO Heritage also continues to offer services for owners of McLaren 12Cs, Mercedes-Benz SLR McLarens and McLaren F1s, while MSO Limited remains responsible for limited-edition models like the MSO 650S that debuted at Goodwood this year.
The fith tier of MSO's operations is MSO Programmes, which handles McLaren's upcoming P1 GTR Driver Programme - an exlusive track day programme for the world's uber-wealthy.
