Front axle needs to be narrowed a bit and some weight needs to be added. Mine ran terribly when I got it but when I realized that the gearwheel was fouling on the pinion and did a small bit of sanding, the performance was transformed. It is very fast and handles (with the stock magnet in place which, I think, doesn't do much at all as it's mounted up front) nice and 'slidey'. Tried some silicones on it but didn't like how it handled (rear end better behaved but car not as much fun to drive and was now prone to rolling, I guess due to sticky tyres and high centre of gravity) nor how it looked.
