Description

UNLEASH THE FULL DYNAMIC POTENTIAL OF YOUR F20 M135i WITH A DEDICATED PERFORMANCE SUSPENSION.

The Blitz ZZ-R Coilover Set is engineered for the BMW M135i (F20) with the N55 engine. It offers a significant lowering range, a rear-biased spring setup for agility, and full damping adjustability.

It transforms the hot hatch’s already impressive handling into a sharper, more planted, and driver-focused experience. As a result, it is perfect for spirited road and track use.

Product Highlights

REAR-BIASED SPRING RATES FOR ENHANCED AGILITY & ROTATION: Features a tuned spring setup (6.0kg/mm front, 8.0kg/mm rear) designed to complement the M135i’s rear-wheel-drive chassis. This calibration helps reduce understeer, promote rotation, and sharpen turn-in response. Thus, it maximizes the driving engagement that defines this performance hatchback.

SIGNIFICANT LOWERING RANGE FOR AGGRESSIVE STANCE & CG REDUCTION: Provides a substantial lowering capability (up to -71mm front, -64mm rear), allowing for a dramatically more aggressive and planted stance. This not only enhances the hot hatch aesthetic but also significantly lowers the center of gravity. As a result, it reduces body roll and improves high-speed stability.

FULL 16-LEVEL DAMPING ADJUSTABILITY FOR FINE-TUNED RIDE: Equipped with 16 levels of damping adjustment on both front and rear shocks. This enables precise tuning of the ride quality, from a comfortable setting suitable for daily driving to a firm, controlled setup. Therefore, you can maximize grip and feedback during aggressive driving or track sessions.

COMPATIBLE WITH STANDARD M135i SUSPENSION (NON-ADAPTIVE): Designed for M135i models without the factory Adaptive M Suspension (electronically controlled dampers). For vehicles with the adaptive system, a separate canceller module is required to disable it and prevent fault codes. This allows this performance-focused mechanical system to take its place.
