Similar to our Competition Coilovers in Features and our Pro Coilovers in Appearance, the VIP coilover provides plenty of performance and style at a reasonable price. These are designed to go scrape-the-frame low, so they have a pretty stiff ride to keep the car from touching down on bumps while maintaining a low height which may be a bit jarring for luxury tastes at speeds below 30MPH but the significant increase in suspension performance is welcomed when cruising smoothly and confidently on these VIP coilovers at higher speeds. - Standard 18kg/mm front spring rates, 14kg/mm rear spring rates give you a firm ride, great for controlling a low ride height car. - Aggressive but smooth damper tuning - Fully threaded damper & lower mount allows vehicle height to be adjusted independent of the spring preload - Large range of rebound adjustment is available at the turn of a knob on the top of each damper - Allows full soft to full hard damping change in just 12 clicks - Replaceable & Custom Tunable Damper - Custom spring rates are available to special order with a proper damper tune (4-32kg) You can choose +/- 2kg with the built in adjustments without spending more money for a custom damper tune. - Pillow ball upper mount on front AND REAR allows you to change track width without binding the coilovers. Perfect for use with extended lower arms or extreme negative camber settings. - Spring upper perch provides independence between the spring and the pillow-ball - Billet T6061 lightweight anodized aluminum rear mounts, collars, perches.
