you can get an ebay kit and be dissapointed, dont forget to factor in the cost of another kin in a year or so, for ride quality and drop, bavauto makes a nice spring, then get a set of bilstein sports, or koni sports, they will last and you will be happy with them. Trist me with the bavauto springs, i have a set and they have a nice ride, btw fuck monroe and tokiko (fowever you spell it)
