I have used Ebiach Pro kit and the Sportline kit before , but I have a ? concerning Tanabe I have heard of this spring manufactory before , but have never none of anyone that had them installed on their car . Now the drop for the Tanabe are 1.8 and the sportline 1.4 and Prokit 1.2 . i know that with the prokit you don't have to worry so much about replacing the shocks right off the bat , but as far as Tanabe with a 1.8 inch drop is that something to worry about ? Also is the springs that they make any good or is it a cheap rip on springs . Isn't it a Japanese market spring ?
