My experience with the car is its been a good experience. I went thru the original top plate issues and only one tank. Since then I've had really good luck. Out of the last 10 races I have run, the only thing I had trouble with (as far as the car) is with the uprade aluminum inputs and a broken upper A arm (hard landing off the triple and I was way out of shape). Nothing wrong with the stock ones, this was just an experiment and I wouldn't recommend them, material is to soft. I do maintain my car probably more than most, but to me it's normal maintance.
Most of these races I've ran 30 min mains and no other trouble.
