i just put together a CRC carpet knife and i am not really sure what to make of it.(all my other cars have been t-plate cars) anyway the center shock is a micro vcs w/blue spring (from my 12L3) and it seems like it pushes way too hard on the top plate of the motor pod.when you look at the car from the side it looks odd. there appears to be a convex angle between the chassis and lower pod plate. is it supposed to be this way?or should i be using a softer center spring?like i said this is my first non t-plate car and i am not sure about initial set up.any suggestions?
