Normally nothing that major. That was the result of a missed shift up front and inexperienced drivers hitting the brakes instead of swerving to avoid or even lightly bumping the car in front. That hit bent my frame rails in front of the shock towers so it is fixable. The hit broke the differential of the car in front of me so he got it pretty bad too.

Normat contact is pretty minor. A light bump draft in the back for sometimes the occasional tire rub on the side of the car is usually the most we get. And all that is only in spec miata. Most other classes have zero contact but we are the most competitive class so occasionsal contact is expected. It is racing after all.
