They one of the many identical kits available from the far east. If I were you I'd buy the version of the kit that has been designed for UK roads as this has the correct spring rates.
Have a look for the thread with the BC racing coilover, it's the same design and quality, just a different colour and actually had some time spent on research and development for a UK car.
There was a lot of hype about these at the end of last year before they were marketed, but the only report I've seen on them is about the poor location of the rear spring. I was expecting a lot more positive feedback
