Add Front Chassis Rigidity to Your GR Supra With Tanabe's Sustec Tower Bar Plus

Tanabe's Sustec Tower Bar Plus connects the front strut towers and radiator support on a 2020-2021 Toyota GR Supra into one rigid structure, reducing the independent flex that lets suspension geometry shift under hard cornering and braking. The Tower Bar Plus revision increases the bar's cross sectional area by about 16 percent over the original Tanabe tower bar design, raising torsional rigidity of the shaft by approximately 138 percent for a noticeably firmer, more connected feel at the front end.

Key Features

  • Ties the front strut towers and radiator support together as a four point brace
  • Reduces independent strut tower movement for more consistent suspension geometry
  • Tower Bar Plus shaft design increases cross sectional area about 16 percent over the original bar
  • Approximately 138 percent greater torsional rigidity than the original Tanabe tower bar
  • Red anodized aluminum construction with steel mounting brackets
  • Adjustable mounting points for fitment

About Tanabe

Tanabe has engineered suspension and chassis components in Japan since 1974, known for its Sustec line of strut tower bars, springs, and exhaust systems built to improve handling feel without sacrificing everyday drivability. The Sustec Tower Bar Plus reflects that approach, offering a measurable rigidity increase over the original tower bar design while remaining a straightforward bolt-on upgrade.

FAQ

Does this bar fit both 2020 and 2021 GR Supra models?

Yes, it is designed for both model years, with additional mounting hardware supplied for 2020 models since their mounting points are not pre-threaded, while 2021 models use the existing factory hardware.

What does this bar connect?

It ties the front strut towers together and also connects to the radiator support, forming a four point brace at the front of the chassis.

Will this fit a 2022 or newer Supra?

This listing covers the 2020-2021 model years, verify the correct Tanabe part number for later model years before ordering.

What color is the bar finished in?

Red anodized aluminum with steel mounting brackets.

Is this bar adjustable?

Yes, the mounting points are adjustable to help with fitment.

Will this interfere with aftermarket intakes or other engine bay parts?

Owners have reported that some aftermarket intake components can contact the bar depending on their design, check clearance with any installed engine bay parts before finalizing the install.

Does installing this bar require any cutting or drilling?

No, it bolts to the factory strut tower and radiator support mounting points, though 2020 models require the included hardware since those points are not pre-threaded from the factory.

Does this bar affect ride quality?

A strut tower bar increases chassis rigidity rather than changing spring or damper rates, so it will not affect ride height or ride quality the way a suspension component would.

Is a Prop 65 warning required for this product?

Yes, this product includes a California Proposition 65 warning.

Installation Instructions

  1. Support the vehicle and open the hood to access both front strut tower mounting points and the radiator support.
  2. Remove any factory covers or components blocking access to the strut tower mounts.
  3. Position the Tanabe Sustec Tower Bar Plus across the strut towers and align the mounting brackets with the factory mounting points.
  4. On 2020 models, install the supplied hardware into the unthreaded mounting points, on 2021 models reinstall using the existing factory hardware.
  5. Torque all mounting hardware to the vehicle manufacturer specification.
  6. Reinstall any covers or components removed for access and confirm the bar does not contact surrounding engine bay components.
