Width
It’s usually best to pick your truck width so that, when fully assembled with wheels, your board will balance on its side, deck perpendicular to the ground. When the wheel track and deck width are matched in this way, you get very smooth leverage on the trucks. Wider wheel tracks give a more stable feel, but your board will be less quick to respond.
Geometry and Spring Strength
Sesmic baseplates come in two geometries: Quick-Turn 45° and Stable-Turn 30°. For most boards, using a 30° truck at the tail and a 45° truck at the nose maximizes power, control, traction and stability. Exceptions: big vert, technical street and downhill boards (use 30° trucks on both ends) and low-speed recreational carvers (use 45° trucks on both ends)

Seismic springs come in eight different strengths. The preinstalled springs are designed to optimally blend turning ease, stability and resilience for the average user. Of course, what works best for you will vary depending on size, style, personal preferences, and the disciplines you practice.
The Seismic metal coil springs’ rapid energy return capitalizes on your thrust-carving action more efficiently than traditional urethane grommets (which are basically primitive dampening springs). The quicker the board rights itself after you unweight, the stronger you can pump.
At higher speeds, and during technical maneuvers, some skaters prefer more dampened truck response, especially at the tail. A urethane-based high-dampening spring assembly is currently in development.
For more stability, increase spring tension, buy heavier springs, or switch to the stable-turning baseplate. For more maneuverability, decrease spring tension, try lighter springs, or switch to the quick-turning baseplate.
