**This kit is for fast freeride = Cupped washer on back boardside and flat washers on the rest.**
The cupped and flat washer on the back truck will create a tighter more stable truck, it will allow you to have a more janky front, allow you to bounce into those tight corners fast, rail out for maximum speed.
One of the benefits of a precision truck is it has built in space for bushings, this restricts the bushing and gives a precise feel when turning or leaning. What we mean is the lean is the same through out the turn, you don't get a sudden jerk somewhere in the lean when the bushing deforms. By using precision washers, you can create this same performance with a cast truck without the extra cost of buying precision trucks.
