EVERY 1:8th buggy on the market suffers from unwanted steering input due to chassis flex. This upsets the car in corners and when hitting bumps. Not anymore for the Mayako, with the new floating steering servo mount that connects all steering parts directly to the front gearbox. These parts are currently being tested and developed by the MPC (Mayako Performance Community).
Below you can see a video of how the assembly flexes while steering angle stays constant.

Your "Kevin" is a unique measurement that is the distance from the top of your MYB0190 Steering Servo Bracket, to the bottom of your servo. In the below image you can see my "Kevin" is 32mm. This measurement will help you determine how many shims you need to add between the two plates, in order to set the correct height for the servo to clear the chassis with enough space to not hit when the chassis flexes.
42mm - "Kevin" -3mm = Xmm Shims : 42 - 32 - 3 = 7mm Shims
With this setting, in the below image the servo would be 2.29mm above the chassis, and 3.79mm above the machined pocket under the servo. So the only thing you need to measure, is your KEVIN! Then add shims so you achieve the 42mm target measurement.
*For the autistic readers, yes I have 8mm shims in the picture, but I wanted to use simple nice even numbers to make it easy! With a Kevin of 31mm, you would use 8mm shims!
Ensure you buy the correct Servo Plate for your Chassis length!
