there ok but you would be better of spending a little more more something better, i love my bilsteins and bought them on ebay for 460.00 shipped, you could get tokico blues if $$$ is a problem i think those are like 250.00 on ebay and are alot better than the kyb's but if you can get the bilsteins, its the best money you will spend and will last forever!!
I agree with juiced... If you can afford them, get the bilsteins, YOU WILL NOT be disappointed. I have Eibach pro's with Bilsteins on my Vert. It gives it an overall nice drop, firm but not harsh ride, and it handles real nice. I also did a full length subframe connector, strut tower brace, and Caster Camber plates at the same time. So there was a drastic difference.
