The Brennan Racing Sequential Gearbox has been built and designedfor the serious racer. The Brennan transmission is based around the original Hewland 5 Speed STA Transmissison but has been totally re-engineered using the same equipment and technology that is used in other Brennan Racing products.
Brennan Racing has worked closely with Hewland on this project.Hewland manufacture the shafts and wide gear sets to bring the high quality associated with all Hewland transmissions to the Brennan gearbox.
All new cases, sequential shift mechanism, selectors etc are designed, modelled and produced by Brennan Racing. Each gearbox is hand assembled and checked for correct operation prior to shipment with customers choice of ratios.
Brennan gearbox assembled in car ready for first test.

Oil Quantity : 1.9 litres or 2 qts Oil Recommendation – Redline Heavy Shockproof Gear Oil has proven to be by far the best choice.
Hi Performance road rated gear oils have proven to be insufficient to lubricate and cool these transmissions.
