Matching your gear ratios to your engines torque curve, diff ratio and tyre size is critical to keep your car accelerating hard. LCR offers a huge range of options around gear boxes and ratios including helical and straight cut gear sets with either synchromesh or dog engagement systems and adaption options where required.

Using computer aided modelling, LCR can establish the best possible ratio combination for your project ensuring you gain vital seconds per lap by keeping your vehicle at its peak torque point at each shift.

LCR has extensive experience with the Nissan FS5C71B 5-speed gearbox (shown here) used in Nissan/Datsun competition vehicles since the early 1970s. Solutions using this basic box can be provided for all genres of motorsport, even for vehicles exceeding 400bhp.
