Overview

By suppressing strut house deformation and body twisting during cornering, it improves overall handling and steering response.

The bolt-on component features an oval shaft with 20 mm x 40 mm dimensions and 1.6 mm thickness, providing high torsional rigidity. It is compatible with both automatic and manual transmission models.
Show original supplier description
This connection effectively suppresses the "falling phenomenon" of the strut house and mitigates body flex during cornering, which improves steering accuracy and suspension stability. The bar allows for a more direct steering feel, which aids in controlled driving. Constructed from aluminum, the unit features an oval pipe design measuring 20 mm x 40 mm with a wall thickness of 1.6 mm for high torsional rigidity. The installation is a straightforward bolt-on process with a reference work time of approximately 0.5 hours. It is compatible with both automatic (AT) and manual (MT) transmission vehicles and can be installed in conjunction with the front upper frame brace. Fitment is confirmed for A-type through late E-type vehicles. However, this product is not compatible with TGR 86 / BRZ race models, and users participating in those events should purchase a specifically compatible product.
