Adjustable upper rear wishbone TT02

Adjust the rear geometry of your TT02 with precision

The adjustable upper rear wishbone for the Tamiya TT02 chassis is one of those small tuning elements that makes a noticeable difference in the car's behaviour. By replacing the stock rigid bar, this component allows for the adjustment of the rear suspension geometry and adapts the setup to the demands of each track or driving style.

Function and performance

The upper rear wishbone controls the camber angle and the toe of the rear axle. With an adjustable version, we can modify these parameters without the need to change parts, simply by acting on the length or position of the wishbone. This translates into:

• Increased responsiveness in corners.
• Better straight-line stability by correcting small geometry deviations.
• Fine-tuning of load distribution on the rear axle.
• Ability to adapt the setup to different surface types and layouts.

Compatibility

This wishbone is specifically designed for the Tamiya TT02 chassis and its variants. The TT02 is one of the most widely used all-wheel-drive chassis in competitive and recreational radio control, with a large community of tuners and good availability of spare parts and upgrades in the market.

Installation and preparation

The installation is straightforward, following the usual disassembly process of the TT02 rear end. We recommend taking the opportunity to check the condition of the ball joints, axles, and rear shock absorbers. Once installed, it is advisable to make geometry adjustments on the bench before going on track, ensuring that both sides are symmetrical to avoid unwanted drifts.

The adjustment should be done progressively: start from a neutral setup and modify in small increments, noting the changes to reproduce the optimal setup for each track.

Common mistakes

• Asymmetry between sides: always check that both wishbones are the same length before tightening them down.
• Worn ball joints: an adjustable wishbone loses effectiveness if the ball joint ends have play. Check their condition before installation.
• Over-adjustment of negative camber: an excessive camber angle can increase tyre wear and reduce traction during acceleration.

Frequently asked questions

Is it compatible with all versions of the TT02 chassis?

It is designed for the Tamiya TT02 chassis. We recommend confirming compatibility with specific variants such as the TT02B (buggy) or the TT02D (drift), as they may have differences in suspension geometry.

Do I need special tools for installation?

No. Installation is done with standard radio control tools: Allen key and screwdriver. No special tooling is required.

What is the difference compared to the stock wishbone?

The stock wishbone is a rigid piece of fixed length. The adjustable version allows for modification of the effective length of the wishbone to regulate the camber angle and rear toe, something the original component does not allow without replacing parts.

How often should I check this component?

We recommend inspecting it after each demanding session or after any significant impact. Pay special attention to the condition of the ball joints and ensure that the adjustment systems have not lost position due to vibrations.

The Tamiya TT02 adjustable upper rear wishbone (ref. YETT02-004BU) is a precision upgrade part that allows fine-tuning of rear suspension geometry, including camber and toe settings. A must-have for TT02 builders and competitors looking to optimize their chassis setup for different track conditions. Compatible with Tamiya TT02 chassis and variants.
