GTR-33 Tanabe front tower bar

A Tanabe Sustec Tower Bar is an aftermarket car part designed to improve handling and stability by reducing chassis flex.
It connects the strut towers, which are the mounting points for the suspension struts, to create a more rigid chassis.
This increased rigidity helps the suspension system function more effectively, leading to better handling, especially during cornering and high-speed driving.

Here’s a more detailed breakdown:
Function:
The primary function of a strut tower bar is to reinforce the chassis by connecting the strut towers. This prevents the towers from flexing independently, which can cause the suspension geometry to change slightly and negatively impact handling.

Benefits:
By reducing chassis flex, the tower bar can improve:
Handling: Making the car more responsive and predictable, especially in corners.

Steering Precision: Providing a more direct feel to the steering.

Driving Stability: Increasing stability, especially at higher speeds or on uneven road surfaces.

Construction:
Tanabe tower bars are typically made with a combination of materials, often including:
Aluminum: For lightweight construction.

Steel: For strength and durability.

Features:
Some Tanabe tower bars may include features like:
Adjustable preload: Allows for fine-tuning of the bar’s tension.

Quick release levers: For easy removal of the bar, if needed.

Installation:
Installation is generally straightforward, but some models may require minor adjustments or harness rerouting.

In essence, a Tanabe Sustec Tower Bar is a relatively simple modification that can provide noticeable improvements in a car’s handling and overall driving experience.
