ROC's sports springs are designed to safely lower your vehicle by up to 50mm, enhancing road handling and providing a sportier driving experience. These kits are specifically engineered for use with the original shock absorbers, although gas shock absorbers can be added for further ride improvement. ROC places a strong emphasis on precision in their spring design, using in-house specialist software to achieve the desired performance outcomes. While ROC's sports springs provide moderate lowering (20-50mm), the primary focus is on improving driving dynamics rather than just aesthetics. Lowering the centre of gravity and increasing spring stiffness significantly reduce body roll during cornering, minimize "nose dive" during braking, and decrease "squat" during acceleration. ROC is the largest manufacturer of aftermarket chassis springs in Europe, and their state-of-the-art facility is dedicated to quality, flexibility, and environmental sustainability. Their springs are crafted from high-quality spring steel, with options for oil-quenched or unquenched wire. Stress relief processes ensure fatigue strength and resilience. Corrosion protection includes zinc phosphate and epoxy powder resin paint, meeting industry standards. ROC's quality management system adheres to ISO/TS16949:2009 standards, focusing on design, development, and production of automotive products. Spring identification is a crucial part of their process, ensuring accurate product tracking. Every spring undergoes a comprehensive quality control procedure, including load testing, and surface treatment is performed with advanced zinc phosphate methods for corrosion protection and a polished finish. ROC's meticulous approach to spring manufacturing ensures top-notch quality and performance for each product. Always check that the springs diameter and end shape are correct before attempting to fit it into the spring pan. We recommend that instructions from a recognised repair manual are followed when fitting a spring. Special tools should always be used to compress a spring. Always take great care since a compressed spring holds a huge force and could cause serious injury if it came loose during fitment. Spring pans, bushings and link arms should always be checked for damage. After installation check that the springs are correctly located at the ends and are not too short or loose. Always check the wheel alignment after installation. For cars equipped with a self-levelling system, adjustment may be required after fitting sport springs. For cars equipped with load dependent brakes on the rear axle, these must be checked and if necessary adjusted by an expert after fitting the sport springs. All springs are inspected and tested before delivery, which guarantees high quality. All ROC springs are manufactured in accordance with ISO9001 & ISO14001, and in a TS16949 environment.
