Using this gas cartridge, our team found that our car handled better on BUMPY roads and had a smoother ride overall. The improved shock absorption made a noticeable difference during sharp turns and sudden stops. The durability of the product was also impressive holding up well under various weather conditions. The only con we experienced was a slightly stiffer ride, which may not be preferable for all drivers.Overall, we would highly recommend this gas cartridge for anyone looking to improve their car`s suspension system..
