"With the RC8B4 one of my favorite features is the new steering geometry. This has really changed the game when it comes to all the different conditions and track surfaces we race on. This has really improved the tuning window from track to track without changing car setup." - Spencer Rivkin

The new Team Associated RC8B4 has a variety of new updates to the geometry to help get more performance and stability while providing the best driving experience
Front and Rear Gearbox
The front and rear gearboxes have received crucial updates. The front gearbox features a 3.5° incline allowing for a straightened driveshaft, increasing drivetrain efficiency. The rear gearbox uses a 0° pinion angle, maintaining this straightened driveshaft system. Both gearboxes use oversized bearing for longer bearing lifespan.

The front upper and lower suspension arms have been designed to accommodate a wide range of flex and stiffness options. Optional inserts have been made to provide extreme fine tuning and will work with the upper or lower arm. The lower arm features a one-piece anti-roll bar link mounts that are in-line with the anti-roll bar for simplified assembly and operation.
Rear Suspension Arms
The rear arms have been designed for optimum flex and stiffness with no inserts. However, optional inserts may be used for fine tuning. The rear arms also feature a one-piece anti-roll bar link is mounted in-line with the anti-roll bar with a BHCS instead of a shock pin for simplified assembly.

This kit does come with grease and all the oils needed for the shocks and differentials. The description says you need to purchase fluids but that is not true. This also comes with a flywheel/clutch kit and a clutch bell. The only thing needed in this kit are servos, on/off switch, battery, engine/exhaust, wheels/tires and of course transmitter/receiver. I also purchased blue aluminum servo mount grommets but is not needed. This is a great kit to build for beginners or veterans to the hobby.
