4SRC Clubman Spec 4-Point Half Roll Cage – Made in the UK

4SRC Clubman Spec 4-Point Half Roll Cage – Made in the UK

Introducing the latest evolution of the 4SRC Clubman Spec 4-Point Half Roll Cage, precision-engineered and manufactured in the United Kingdom for all model-year Nissan GT-R R35.

Our latest production now utilises 45mm x 2.5mm CDS (Cold Drawn Seamless) tubing, built to E355+N specification— fully compliant with the Motorsport UK “Blue Book” regulations.
This upgrade provides improved rigidity, strength, and long-term safety compared with the previous 40mm version, while maintaining excellent weight balance for track use.
The complete assembly weighs approximately 24kg.

Unlike roll cages designed purely for aesthetic appeal, the 4SRC Clubman Spec cage is engineered with a clear purpose: to enhance the structural stability, chassis stiffness, and overall safety of your GT-R.
Our unique rear support geometry increases body rigidity under high lateral load, improving the driving feedback and safety margin far beyond basic harness bars or show cages.

Featuring a bolt-in design, this cage allows full reversibility — it can be removed to return your car to OEM condition with no permanent modifications.
Perfect for track days, time attack, and fast-road use.

All cages are finished in matte black, which is kept in stock for immediate dispatch.
Custom colours and finishes are available to order, with a typical lead time of 10 working days.
Please plan your installation schedule accordingly when placing your order.

Choose the 4SRC Clubman Spec Half Roll Cage — the ultimate balance of performance, safety, and British engineering excellence for your Nissan GT-R R35.

Specification Update (Effective November 2025)

As part of 4SRC’s ongoing product development and commitment to Motorsport UK standards, the Clubman Spec Half Roll Cage has been upgraded to the latest specification.

All units produced from December 2025 onwards now utilise 45 mm × 2.5 mm CDS (Cold Drawn Seamless) tubing, manufactured in the UK to E355 + N specification — fully compliant with the Motorsport UK “Blue Book” regulations.

Orders placed from mid-November 2025 onward will automatically receive this updated version.

Cages supplied before this date were produced using 40 mm × 2.0 mm CDS tubing, built to the same geometry and fitment specification.
Both versions meet 4SRC’s internal strength and safety requirements, with only a small difference in tube size and wall thickness.

There is no compatibility or safety disadvantage for earlier customers, and all 4SRC roll cages remain covered under our standard warranty and support policy.
