Billet Aluminium Rear Chassis Brace I MINI F55, F56, F57

The G54 Rear Exhaust Tunnel Chassis Brace is designed for MINI F55 and F56 models and strengthens the rear section of the central underbody structure. Positioned around the rear exhaust tunnel mounting points, it helps create a firmer connection across the floorpan where the original vehicle relies on lighter pressed or stamped components. The aim is not to transform the car into an uncompromising track vehicle, but to add useful structural support that can be appreciated through more settled chassis behaviour and a cleaner response during changes of direction.

Machined from solid 6082 grade aluminium billet, the brace uses carefully positioned ribs, pockets and mounting lands to retain material where loads are transferred while controlling overall weight. CNC manufacture provides accurate hole positions and flat mounting faces, helping the component locate correctly against the original attachment points. This attention to detail also gives the brace a distinctive engineered appearance when viewed beneath the vehicle.

An anodised finish protects the aluminium from corrosion and road contamination while allowing owners to coordinate the brace with other G54 components. It is a practical, visible example of the G54 philosophy: design a product that solves a real engineering requirement, manufacture it properly and offer it at a price that makes sense for an enthusiast road car.

G54 products are designed, engineered and manufactured to be used. The warranty is kept simple: if a G54 product develops a genuine manufacturing or material fault, G54 will put it right.

Lifetime Warranty

Unless stated otherwise, G54 products are covered by a lifetime warranty to the original purchaser against defects in materials or manufacture.

The lifetime warranty applies for as long as the original purchaser owns the product and is not transferable.

To make a warranty claim, the original purchaser must provide:

• Proof of purchase or original sales receipt
• Valid identification confirming they are the original purchaser

Moving Components

Components such as bearings are covered for 2 years from the original date of purchase for the original purchaser.

Consumable Components

Consumable items are covered against manufacturing defects for 12 months from the original date of purchase.

Consumable components and moving parts are not covered for normal wear and tear.

Installation

G54 products must be installed correctly by a competent person using appropriate tools and suitable installation procedures.

Where applicable, vehicle manufacturer procedures and torque specifications should be followed unless stated.

Damage resulting from incorrect installation is not covered by the G54 warranty.

What Isn't Covered?

The G54 warranty does not cover:

• Normal wear and tear
• Incorrect or improper installation
• Misuse, abuse or accidental damage
• Damage caused by another faulty vehicle component
• Use on a vehicle or application for which the product was not designed
• Unauthorised modification or alteration of the G54 product
• Cosmetic damage occurring through normal use
• Corrosion or damage caused by inappropriate chemicals, cleaning products or environmental contamination

Normal use of a G54 performance component for its intended purpose does not invalidate the warranty.

Making a Claim

Warranty claims should initially be made through the retailer from which the G54 product was purchased.

Proof of purchase, identification and photographs or other information reasonably required to assess the fault may be requested.

G54 may require the product to be returned for inspection before a warranty claim can be approved.

Where a product is confirmed to have failed as a result of a manufacturing or material defect, G54 will, at its discretion, repair or replace the affected product.

Unless otherwise agreed, this voluntary warranty covers the G54 product itself and does not include installation labour, vehicle recovery, vehicle hire or other associated costs, except where such costs must be covered by law.

Statutory Rights

The G54 No Nonsense Warranty is provided in addition to the purchaser's statutory rights and does not affect those rights.
