coiloves on ebay

Hi. I need some advice on coilovers. I've seen some from hottuning on ebay, never heard of them but u never know. They are for a 147 gta, now the standard gta dampers are far from good so even if these others aren't the best if there an improvement i may go for them. Cant really afford kw for a grand!
These are the rates.
F=12k-672ft/ibs
R=18k1008ft/ibs.

Dont relly understand about the rates so if somebody could shed some light would be greatful.
cheers

Not sure, but they look a bargain.
