Hi guys, I am preparing my car for the upcoming season, and I need little bit of help here. I race my pro 4 last season (this season too) on a temp asphalt track with robber tires. I just can’t seem to get enough steering. I tried one way, but the car is too responsive and not consistent. I also tried front spool, but the car chatters like crazy when off power. It has a lot of steering coming out of corner, but understeer or pushes like a dump track off power. I am running the original pro 4 with stock 2.5mm chassis. Will change to a 2.0mm chassis give me more grip?
