Hi will
The biggest thing that influences the way the truck handles are the bushings. If you’ve ever been to the evolve kart track events a good example is we go round that with airs no problems and that is tight in places.
There’s a whole thread dedicated to tuning the trucks that you can find here, well worth a read
Also we sell a pack of bushings I think you would be well placed to get
These work really well in combo with the original bushings that would have been on the trucks when they were first bought. If you don’t have them we can also provide those.
I hope that helps, if you need any particular help at all please get in touch and we will do our best to get you going. They deffo take a little bit of getting used to if you are used to channels but once you have them dialled in and get your weight placement sorted they are fantastic.
