Sorry its very late i do replay but now is better than never.
Yes the works cars had drysump and discbreakes but only front at the rear the drumbreaks where bigger than standart.
The suspension front and rear are very sophisticated, only this three works cars had this suspension and some of the very late works cars MK1 Lotus Cortinas. Gears are strait cut 4 speed only and a lock diff. Engine FVA Ford 1599 ccm 4 valves.
The is a new article in the italien Magazin Januar 2009 "Ruoteclassice" with a lot of fotos me driving the car and some details.
Hope You can find it will give a link from an other Article in USA Lotus page in the internet-it will follow soon
With kind regards
