The pinnacle of shaft drive 4WD touring chassis
A brand new chassis that bears the name of the pinnacle of shaft drive 4WD touring chassis “TB EVO” will be released for the first time in five years. By combining a new-shaped carbon chassis with a minimal upper deck, it achieves optimum pitching rigidity and a low center of gravity for driving. The main chassis also adopts a mechanical plate and center stiffener. The front and rear aluminum bulkheads have also been redesigned to provide superior strength and drive efficiency. The suspension uses the same upper and lower arms as the TA08 PRO to maximize tire grip. SSBB (Super Short Big Bore) dampers are standard equipment for both front and rear. The motor mount has a structure that allows easy backlash adjustment, and two types of motor layout can be selected: front mid/rear mid. Based on the data obtained from the previous “TB EVO” series, we pursued speed, maneuverability, and maintainability, and the “TB EVO.8” was born.

- The damper stays extending from the left and right independent rear upper bulkheads are made of aluminum to ensure high strength. In addition, the mounting position of the SSBB damper can be selected from 4 locations, and the adjustment range is also wide.
-
- A total of 8 kingpin suspension balls, which integrate the flange pipe and kingpin, are used for the front and rear suspensions. Made of lightweight and high-precision aluminum, it enables smoother movement of the suspension. Suspension clearance is also kept to a minimum for greater maneuverability.
-
- The rear suspension adopted on the TA08 allows the rear toe angle to be adjusted even by changing the length of the tie rod, making it easy to change settings. Furthermore, the height of the outer pillow ball can be changed by adopting a rear knuckle. The amount of change in toe angle can be adjusted according to the movement of the suspension arm, expanding the range of settings.
-
- The steering wiper adopts a reverse wiper type with a post installed on the bulkhead side to reduce the impact on the chassis roll. Compared to the TB0EVO.7, the steering tie rod has been extended by 1mm on one side to reduce steering changes during cornering, resulting in smoother driving.
-
- Adopted a newly designed motor mount that can be easily adjusted with two screws from the top of the chassis so that the backlash adjustment of the motor can be performed quickly. The spur gear also has a shape that can be replaced by removing the four screws on the motor mount, improving maintainability.
-
- The aluminum center stiffener attached to the main chassis center can be set to adjust the chassis rigidity with the type and number of mounting screws, and a carbon mechanical plate can also be attached. By installing an RC device on the mechanical plate, we have realized equalization of the left and right balance of chassis rigidity.
