For Service to Racing Car Transmissions.Hewland Engineering have been designing and manufacturing gearboxes and transaxles for racing cars world-wide, since the 1960's. I am Hewland's agent in the English Midlands.
My service is backed by experience of Hewland products going back to 1973. I offer a personal service for Hewland competition gearboxes. By 'personal', I mean that I will always consider your individual requirements, and after inspecting your gearbox I will consult with you fully before continuing with the work. Most of my work is servicing the popular transaxles such as Mark 8/9, LD200, FT200, FG400, DG300 ranges, and the newer NST, NMT and NLT sequential units, from a full overhaul to small adjustments, or the supply of gearboxes, gear ratios (new and second hand), spares, gearing information and gear charts.
My workshop is located at Clifton Avenue, Long Eaton, which is 5 miles from M1 junction 24/A42, 3 miles from M1 junction 25, 4 miles from A50 and 8 miles from Donington Park Race Circuit. Callers are welcome, but please by prior arrangement.
