Just bought this car. Still breaking it in and tuning it. I still want to tune it a bit more before I take it out onto a tar track. I replaced the rubber tires and went with slicks and it handles very well on the street. It does lower it more than stock tires by about a 1mm. It sits 5mm stock. Any tips and recommendations for this car? I'm running 20% Nitro fuel with stock glow plug. Only use it for street and some track runs. Had to cut holes in the body for air circulation.
