Hi ! I would like to know if this is working good or I'm doing something wrong. I have designed a simple car using physics and wheelcolliders. I'm using a RWD configuration. I made a quick GUI text to show up each wheelcollider rpm and the difference between front wheels and rear wheels is quite a lot. So, FL / FR / BL / BR correspond to each wheel RPMs. At full torque (8000), this are the RPMs : As you can see, back wheels reach a maximum of 146k rpms aproximately, while front wheels move around 500-1600 rpms rapidly. Am I doing something wrong or did I miss something ? By the way, I'm using Unity 5.0.0f4 Personal. Thanks in advance.
