Hi Spec Vauxhall Nova 300mm Billet 4 Conversion Kit Showcased In-Store
At GSM Performance, we’re always excited to see premium performance parts come through our showroom for a quality check before being dispatched to our customers. Recently, we had the pleasure of showcasing the Hi Spec 300mm Billet 4 Conversion Kit designed specifically for the Vauxhall Nova. This performance brake kit is a high-spec upgrade solution for classic hot hatch owners looking to maximise both stopping power and safety—especially when driving on track or pushing the limits during spirited road use.
Finished to Hi Spec’s usual precision-engineered standard, this 300mm conversion kit was reviewed, checked, and showcased in our display space before being sent out to one of our enthusiastic customers. While it’s not listed on our main website just yet, this kit is fully available through us, and we’re happy to help any Vauxhall Nova owner looking for a major braking upgrade.
Why Upgrade Your Brakes on a Vauxhall Nova?
The Vauxhall Nova may be a lightweight classic, but when performance mods start stacking up—engine swaps, sticky tyres, or track-day suspension—it’s essential that the braking system keeps pace. The factory braking setup on the Nova was never designed for today’s fast-paced track use or high-powered road builds.
Upgrading to a Hi Spec 300mm Billet 4-piston brake kit significantly improves:
- Brake bite and modulation under hard braking
- Heat dissipation for better resistance to fade during long sessions
- Overall safety when driving at the limit
Whether your Nova is a show car, track tool, or road-going performance build, enhanced braking is one of the most important upgrades you can make.
What’s Included in the Hi Spec 300mm Billet 4 Kit?
This complete brake conversion kit includes everything required for a clean and precise installation onto the Nova. The components are all high-end and tailored specifically to fit the chassis, ensuring no modifications or bodge work is needed:
- 2 x Billet 4 Radial Calipers – Lightweight and strong for improved pedal feel and stopping power
- 2 x Aluminium Bells – For easy and reliable fitting to the Nova’s hubs
- 2 x Straight Vane Rotors
- 2 x Brackets
- 1 x Rotor/Bell Hardware Pack
- 1 x Bracket Hardware Pack
- 1 x EBC Standard Road Pads (Upgradeable) – Matched for the calipers to give consistent braking performance
- 1 x Dot 5.1 Brake Fluid
- 2 x Braided Hoses (Optional)
The complete package is designed to bolt straight on and offer a genuine step-up in brake performance.
