if i where to get sleeve coilovers would i have to get shocks as well
I would say you should. Most sleeve-type coilovers run linear springs with higher than stock spring rates (I believe most of them are around 400lbs. pending on application). And factory shocks are matched with very soft springs, so they wouldn't stand up to the higher rates. But I think you should fair well if you don't go "slammed"; just a mild drop.
For example, a friend of mine runs generic coilovers on his DC integra which are fairly stiff, and has been running with them for about 3 years already. The ride isn't too bad and his shocks are still holding up quite well, but then again, he isn't slammed. He's probably an 1.5" drop all around as of right now.
But, since you do all the work to get the coilovers installed, why not replace the shocks as well? It's less of a hassle in the future.
