Description

REFINE THE OPEN-TOP EXPERIENCE WITH ENHANCED AGILITY AND A PERFECT STANCE.

The Blitz ZZ-R Coilover Set is engineered for the BMW Z4 (G29) with the B58 inline-six engine. It offers a tuned spring setup, comprehensive adjustability, and a significant lowering range.

It transforms the roadster’s grand touring character into a more precise, engaging, and visually striking driving machine. As a result, it’s perfect for spirited cruises and backroad enjoyment.

Product Highlights

TUNED SPRING RATES FOR ENHANCED ROADSTER AGILITY: Features specifically calibrated spring rates (6.0kg/mm front, 8.0kg/mm rear) to complement the Z4’s chassis. This rear-biased setup sharpens turn-in response, improves rotation, and reduces body roll. In addition, it enhances the open-top driving experience with more connected and predictable handling.

ADJUSTABLE FRONT CAMBER PLATES FOR PRECISION ALIGNMENT: Equipped with adjustable pillow ball upper mounts on the front struts. This allows for precise negative camber adjustment, optimizing front tire contact during cornering to maximize grip. Moreover, it improves steering feedback and ensures proper tire wear for enthusiastic driving.

COMPLETE CONTROL OVER HEIGHT AND DAMPING CHARACTER: Offers extensive adjustability to tailor the vehicle’s personality. Provides a substantial lowering range (up to -55mm front, -50mm rear) for a more aggressive, ground-hugging stance and a lower center of gravity. Additionally, it features 16-level damping adjustment on both axles to fine-tune ride comfort from compliant to firmly controlled.

OPTIONAL ELECTRONIC CANCELLER FOR SEAMLESS INTEGRATION: For vehicles that trigger a suspension warning light, Blitz offers an exclusive optional canceller (Part# 15218). This ensures a clean, fault-free installation by deactivating the vehicle’s chassis monitoring system. Consequently, this allows for a professional upgrade without dashboard warnings.
