When i bought it they were about $950 shipped (i think).
Just email titanmotorsports.com and they'll get u a price.

You will have enough travel space if u lower ur car 2inches on stock shocks, the guy has obviously not seen alot of our cars and thats probably why he is giving u false information. The only thing he is correct about is they will wear your shocks prematurely.

lets get one thing in perspective, cd5's use a coilover suspension system for both front and back, so the stock system is a coilover system.
You can change just the springs to k-mac or whatever and keep the stock shocks. then once your shocks begin to wear out you can change your shocks.
The only real benefit of getting a coilover system (whereby the springs are made for the shocks and are made by the same manufacturer) is normally the fact you can get height adjustability anywhere within a certain amount.
Whereas if u get lowered springs (kmacs) and u then want to upgrade your shocks, u have limited yourself to getting shocks which may have height adjustability but normally have perches where u can pick from 3 heights.

depending on how much your willing to spend teins are a good option, however for the time being u may just want lowered springs....because they are far cheaper.

Where about are you from?
