Dear God don't do it, they look similar to the FK Street coilovers I made the mistake of buying.
They are horrific, they bounce far too much, and are borderline dangerous through corners they are so bouncy!
If your after cheap lows they work, but the drive of your car is utterly destroyed.
Coilovers are a go big or go home situation, go for at least some AP (derived from KW - Weitec) or a decent shock and spring kit.
Just my 2p, but I would save until you can afford something that's not going to kill you.
