we´re talking about TM and not about RDL. RDL is only a reseller and not the builder of the car.
as 4racer said, we have to put so much money into the car, to become more competitive but that´s not the way.
nickko, make a new class modell.
for example, the e-class evo including ufo clutch, new steering, new belts, new brake disc and the new brakepads. and call it the r-class (r=race). make a good price and you will see more G4 drivers all over the world!
