For those customers who are serious about straight-line performance, this product offers a huge leap forward. RSC's Crown Wheel and Pinion kit changes the Vantage final drive from a tall 3.9:1, to a much more aggressive 4.55:1

This means much faster acceleration, and although gearbox ratios remain the same, they are brought closer together in gross terms. This helps you keep the engine 'on the boil' and maximise the powerband.

RSC developed this product through a racing partnership which has seen it extensively tested (read: thrashed within an inch of its life) over multiple racing seasons. The extremely high quality construction and engineering which went into it gives it outstanding durability on the road or track.

Engine RPMs in 6th gear at 60MPH are increased from 2305, to 2683, assuming wheel/tire aspect ratio is the same as factory spec.
