I got me a Ninco Merc CLK (NC 2) to race in our club's GT class. I have done everything I should have done to prep it except stabilizing the front wheels. It's a short 25m track and nobody is doing it. Anyway, I've raced it twice and had some practice sessions. Last night I saw that the crown has got some teeth missing already. I mean the motor is strapped down, the rear axle is centre, the pinion and grown is lubed. It's rear does bounce a bit if I got full throttle out of the turns but stays down if I do it gradualy. Do I need to change the tires? Has this car got to much power or is it the Ninco geares that are of bad quality?
