I'm just starting racing and still learning the concepts. I had this idea of copying how a real car's transmission and suspension system behaves. The idea was to use tamiya steering system on the front wheels and a front sliding bumper for steering then use one-way wheel set as the rear differential. For the suspension, i'm building the uncut ms suspension by "arena mini 4wd club" youtube page. I plan on doing this build with as minimal modding and as much as possible, use cheap and common parts. I have yet to buy the springs for the ms suspension and the front sliding bumpers. The first issue i encountered was that there was a lot of vibration on the steering wheel set.
