Chassis stiffness can also be fine tuned using 6 chassis spacers depending on track conditions. Aluminum components, such as the rear pod and center shock are anodized with a stealth black finish. The SP-1 F1 1/10th scale chassis also allows different lipo battery positions and configurations. The SP-1 can fit regular size 2 cells lipo battery or the shorty 2 cell lipo packs. The SP-1 F1 1/10th scale chassis represents Speed Passion\'s high quality standards on and off the track as racers can put the chassis\' craftsmanship and attention to detail on display.
