That's what i also noticed this wknd when we had our first tamiya-cup race, this car has so much potential that it could be able to keep up with the TRF cars.
I upgraded my car with the carbon reinforced parts and some other parts to reduce the weight and with a lightweight nsx body it only weights arround 1360gr and still able to save some extra weight.
And even when the car is light it still performs great.
