Hi,
To be honest we rate our kits slightly above the quality of the Hottuning units. Ours are a european made unit as opposed to a far east based product. Our warranty is held in house, so should the worse occur we are equiped enough to deal with the problem. You will note the alloy adjusters on our units are silver as oppsoed to anodised blue.
I hope this helps. We are trying to delvier a quality product and great service at an affordable price. We are about to unveil a new program of suspension that is far superior to the current UK market place. News will follow soon.
