TB Performance Rear Under Brace

2005–2010 Scion tC

Part #: TB-RUB-TC

Overview

The TB Performance Rear Under Brace is a precision-engineered chassis reinforcement designed specifically for the 2005 to 2010 Scion tC. This bolt-on brace targets the exhaust tunnel area, a known structural weak point in the unibody chassis. By stiffening this critical section, the brace significantly reduces chassis flex and wallowing, resulting in sharper handling and improved vehicle stability.

Ideal for enthusiasts seeking enhanced cornering response and a more connected driving experience, this under brace transforms the Scion tC’s chassis dynamics without compromising ride quality. Whether on the street or at the track, drivers will notice a more planted feel and confident control through turns.

Key Features

Engineered to deliver tangible handling improvements, the TB Performance Rear Under Brace offers the following key benefits:

• Direct bolt-on installation with no welding or cutting required
• Reinforces the exhaust tunnel area to reduce chassis flex and body roll
• Constructed from durable tube steel for strength and rigidity
• Finished in a high gloss black powdercoat for corrosion resistance and a sleek appearance
• Hand MIG welded for superior build quality and structural integrity
• Designed specifically for the 2005–2010 Scion tC for perfect fitment
• Manufactured in the USA to ensure high standards and quality control
• Improves overall handling precision and driver confidence

Construction & Design

The rear under brace is crafted from high-quality tube steel, chosen for its excellent strength-to-weight ratio and durability. Each brace is hand MIG welded, ensuring robust joints that withstand the stresses of spirited driving and track use. The high gloss black powdercoat finish not only protects against rust and corrosion but also adds a refined, professional look under the vehicle.

Its design focuses on reinforcing the exhaust tunnel, a structural fold in the unibody that is prone to flexing under load. By bridging this weak point, the brace enhances chassis stiffness, which translates directly into improved handling characteristics.

Installation & Fitment

Installation is straightforward and requires no permanent modifications to the vehicle. The brace bolts directly onto existing mounting points on the Scion tC’s chassis, making it a convenient upgrade for enthusiasts of all skill levels. Typical installation time is minimal, and all necessary hardware is included.

This product is engineered exclusively for the 2005 through 2010 Scion tC models, ensuring a precise fit and optimal performance gains without interference with other components.
