We’re testing the new JK 4.5 chassis. I’ve got it flat as a pancake, the guide is set and that’s all I done. It as fast as my one piece stainless steel chassis, but no faster.
Help me go faster!
Thanks

Play with bite bar thickness and shimming the bite bar. I personally start with .055 piano wire and go from there. The more chatter you can get out of the rear of a 4.5 the faster the car will be. Depending on the track you run on you may also play with adding weight which may be a starting reason why your 1 piecer still work reasonably well.
I have 2 that I am going to start playing with in the next couple of weeks.

2 of my racers have built the new JK 4.5" 21 chassis and it is awesome you can drive deeper into a corner on an oval, I have one to build yet, but I drove one and it is awesome!!!!!!!!!!!!!
