Checklist BEFORE RUNNING YOUR NEW 8IGHT-T 2.0 OFF-ROAD RACING Truggy for the first time, you should run down the following checklist in order and complete the listed tasks. We’re sure you’re anxious to get out and run your new 8IGHT-T 2.0 now that it’s built, but please note that fine-tuning of the initial setup is an essential part of building a high-performance racing truggy such as your new 8IGHT-T 2.0.
SETUP GUIDE TIPS AND HINTS FROM THE TEAM Before you start making changes on your 8IGHT-T 2.0 Off-Road Racing truck, you need to make a few decisions. First of all, tires, and how they are setup, have a tremendous impact on overall performance. Before you start making changes on the chassis setup, take a moment to observe a few of the fastest cars at the track and what type of tire and inner liner they are running.
SETUP GUIDE The 8IGHT-T 2.0 is equipped with the rear hub carriers in the middle. A shorter wheelbase (spacers behind the rear hubs) increases on-power traction, rear weight transfer, and has more off-power steering. A shorter wheelbase is better on tight or slick tracks. A longer wheelbase (spacers in front of the rear hubs) decreases off-power steering, is more stable, better in bumps, and has more on-power steering. Sway Bars: The 8IGHT-T 2.0 is equipped with 2.3mm sway bars on the front and rear.
SETUP GUIDE short Ackerman plate responds quicker and has more steering in the middle of the turn. A short Ackerman plate is better suited for tight technical tracks. Camber: More negative camber in the front has more steering and is more responsive. Less negative camber in the front will have less steering and will be smoother. More negative camber in the rear will have less rear traction, but will increase on-power steering and will be less grabby in bumps.
