Few owners of the McLaren 765LT Spider would come out and say it was lacking. But for those that do, Novitec has launched a slew of upgrades that make one of the fastest convertibles in the world even better. The Stage 3 engine management kit adds a ceramic-coated turbo inlet charge piping, race-optimized exhaust system, and ECU tune to raise power output to 840 horsepower at 7,300 RPM. That translates into a 2.5 second 0-60 sprint and a top speed of 205 MPH. Suspension improvements include a spring set that lowers ride height by 0.78 inches and a set of custom-designed Vossen wheels in 20 and 21-inch sizes. Naked carbon fiber trim pieces for the headlight inserts, frunk lid, rear and side air intakes, and entrance panels are also available.
