SW Motorsports continues to push the boundaries of precision and performance with the launch of our new range of lightweight T45 trackday half roll cages. Designed and manufactured entirely in the UK using advanced CNC mandrel bending technology and 3D scanning, these roll cages offer unmatched strength, precision, and fitment for serious trackday and fast-road enthusiasts.
Built to motorsport standards, each cage delivers the perfect balance between lightweight construction, safety, and style — now available in a range of custom colour finishes to match your car’s personality.
Advanced CNC Mandrel Bending — Unrivalled Precision and Strength
At the heart of this new range is our brand-new CNC mandrel bending system, a major investment in precision engineering and quality. Unlike traditional bending methods, mandrel bending maintains the internal diameter and structural integrity of each T45 tube throughout the bend, preventing deformation and preserving strength in critical areas.
Combined with CNC-controlled accuracy, this process allows us to achieve:
- Perfect, repeatable bends for every cage model
- Smooth, wrinkle-free tubes for superior structural performance
- Tight tolerances that guarantee precise fitment and ease of installation
This advanced setup ensures every roll cage meets SW Motorsports’ exacting standards — straight from the machine to the track.
T45 Roll Cages — Lightweight, Motorsport-Grade Performance
Each roll cage is constructed from T45 high-tensile steel, the same material used in professional racing and aerospace engineering. Known for its incredible strength-to-weight ratio, T45 allows us to produce a structure that’s both exceptionally rigid and significantly lighter than mild-steel equivalents.
The result is improved chassis stiffness, safety, and cornering performance — with minimal weight penalty. Whether you’re chasing lap times or simply want to enhance your car’s handling, a T45 half roll cage from SW Motorsports delivers performance you can feel.
3D Scanned Fitment — Tailored to Every Vehicle
To guarantee an OEM-quality fit, every design starts with a 3D laser scan of the vehicle interior. This technology captures every contour, angle, and clearance point, allowing us to model the roll cage digitally for a flawless fit.
This ensures:
- Maximum headroom and visibility
- Retention of key interior trim and usability
- A clean, factory-style installation
From BMW M cars and Porsches to track-prepared Hondas, Mazdas, and Fords — our cages fit with millimetre precision.
Custom Colour Options — Make It Your Own
We know that presentation matters just as much as performance. That’s why our new T45 roll cages are now available in a wide range of durable powder-coated finishes.
Choose from classic black or satin grey, or go bold with motorsport-inspired colours like bright red, racing orange, vivid yellow, or custom hues to match your livery. Each finish is applied using high-temperature, corrosion-resistant powder coating for a long-lasting, professional look that stands up to track use.
Trackday Half Roll Cages — Safety Meets Style
Designed specifically for trackday and fast-road drivers, these half roll cages offer the perfect middle ground between safety, rigidity, and practicality. You’ll experience:
- Enhanced rollover protection
- Improved chassis stiffness
- A purposeful motorsport aesthetic
Each cage is TIG-welded by our experienced fabricators and inspected to ensure compliance with the highest standards of craftsmanship and quality.
