Sup I got a set of Advance Design coilover for Civic/Integra for sale.I just got them back from ground control.It was rebuild and revalev and never got to put them on any car,the owner b4 had them on his car but he bearly drove his car so they are like new.i believe the spring rates are 400 in front and 500 in rear(got to check again).when i was at ground control having them service one of the worker told me that A/D shock are goin up on price they are now 500 a corner Spring are sold separately.So new now they will cost 2400 with out Springs. Im asking 1600 obo. These are one of the nices coilover i had seen,they are very lite weight and a very nice ride(i got another set on my car that i drive on) i think A/D coilover are very much better then tein's and other jdm brand coilovers,u can go low enff that the car sits on ur tires or u can put up to pretty much stock height. for more info on advance design :http://www.advance-design.com/
