Got these for my 05 S55, they are beautiful coilovers to start. Second dampening adjusters are made nice, same with the height adjusters. The only con I’d have for this cars for others who would like to do it themselves is there isn’t a manual or directions, also it doesn’t come cap nuts. Due to the complicated hydraulic system you need to remove the lines from the strut to refit to the vehicle and cap the ends off with a cap nut since the system is shared with the steering system. So I have knowledge to do the job myself but it would of been nice for the company to give instructions for those who need, and cap nuts for all cause many people will end up on a hunt for them! But they look great feel great, they’ll handle the 700 HP soon :) I’ll give another review how they handle more power maybe in the future!
