Info originally posted by dereklola indicates that Mel Lahner purchased RT2-152 or the Toleman RT2-1 which went to south africa where i presume it is the tub that was stripped and copied as indicated by IAN HEBBLEWHITE. If it was copied ,since the fuel cell is larger in the RT2 tubs does this imply that the Lants made in SA are RT2 tub copies. The fuel cell in my Lant has a full height wall from the floor of the tub to the top plate of the tub which has the roll hoop mounted on it. It is different to any RT4 cars i have seen which have a much smaller fuel cell perhaps only half the height of the Lant cell.
Front and rear suspension is by rocker arm
