To answer some of you guy's questions, i haven't had any long term breakage. The only part I've broken was a dogbone & the little ball that the roll bar connectos to. That's because I decided to clip an inside barrier doing about 50mph! I also have a tip for you guys about the side belt tensioner if you run more overdrive in the front. Instead of using the belt tensioner in the required spot put it in the screw hole of the side brace. It'll give you enough tension to use that 21t pulley up front! So far I love the car, I wish I had gotten it earlier. As soon as I raced it I was 3 laps faster with it than with my NTC3. Also, if you're looking for more top-end. Put a Mugen 22t pinion on it, yes it fits.
