BMW Z4 E89 2009-2016 Steel-Braided Brake Hose Set by HEL Performance

Transform the stopping power and pedal response of your E89 chassis with this premium steel-braided hose set. Built by HEL Performance and engineered as a precise, vehicle-specific replacement for the factory rubber flexi pipes, this kit delivers a firmer pedal, cleaner modulation and consistent bite on fast road and track. We fit these on our own cars and customer builds, and the feedback is always the same - sharper feel, more confidence, less vagueness.

If you are searching for a Z4 brake pipe upgrade that resists expansion, survives British weather and keeps your braking consistent when hot, this HEL set is the proven choice. Front and rear axle lines are included for a complete refresh.

Why this HEL hose set is a smart upgrade

• Crisp, predictable pedal feel under repeated hard stops
• Reduces hose swell compared to ageing rubber flexi pipes

• PTFE inner core with stainless over-braid and a protective PVC sleeve

Unlike zinc-plated alternatives, these stainless ends are designed to fight rust for the long term, helping keep unions serviceable and the braking system dependable.
