Thank you for viewing. This is a rear suspension arm that can be attached to the TT02 BT-01. Suspension arm length: 40.5mm * Shortest point 39.5mm Toe-in: 0.8deg Reverse skid angle: 2.4deg This time, to prevent play, the space between the bearings has been redesigned to be slightly wider, and it has been created using PETG-CF (carbon fiber mixed). It can be used on all chassis that use suspension pins. The chassis side mounting part has been changed to 630 bearing retention to eliminate the play, which is a dissatisfaction when installing Tamiya option parts type D suspension, and to reduce friction loss. There is some adjustment range at the front and rear of the chassis side and knuckle side, allowing for slight wheelbase adjustment. The installation direction is specified to be backward, but strength tests have been conducted by several testers at the home course, and the feeling of solidity and kick have been further improved. The larger the toe-in, the stronger the longitudinal traction tends to be, but please enjoy the setting according to your preference. For those who are currently playing with the normal setup, 0.0 to 0.8deg For those who have experienced toe-in knuckles, we recommend 1.2deg. No processing is required for installation, but please adjust the wheelbase with shims or the like. If the bearings fall out due to product precision, please apply a small amount of rubber-based adhesive before inserting the bearings. *The screw threads are treated at the ball joint insertion points, but be careful not to overtighten the screws. The items to be shipped are the two in the photo. Thank you very much. We are committed to same-day shipping. *Since it is 3D printed, it may be damaged by excessive crashes. *Material: PETG-CF Type...Radio control Manufacturer...Tamiya Type...RC parts Radio control...RC limited parts
