SW Motorsports BMW E92 M3 Bolt In Half Roll Cage

The SW Motorsports BMW E92 M3 Bolt-In Half Roll Cage is a high-quality safety upgrade designed for track day enthusiasts who want added protection without the complexity of a fully welded-in cage. Manufactured using the same materials and processes found in SW Motorsports’ competition builds, this half cage offers a strong, reliable level of rollover protection while retaining a practical, bolt-in design suitable for home installation.

Constructed from 45mm x 2.5mm CDS (Cold Drawn Seamless) tubing to E355+N specification, the cage meets the material standards mandated by Motorsport UK regulations (Blue Book). The design focuses on strength, precise fitment and ease of installation, making it an ideal choice for drivers who regularly attend track days and driver training events. Supplied complete with all required fittings and fixings, the cage can be installed using basic hand tools and removed if required.

For customers looking to tailor their setup, SW Motorsports can also offer custom variations, including additional bracing, hoop cross options or strut brace integration. The cage can be powder coated in a wide range of colours, allowing it to match your interior or personal preference.
