i know this might be a n00b question or you will tell me to use a search, but i cant find what im looking for wthout hunting through LOADS of results

anyhow, im considering lowering my car, very slight, possibly 1.75 in the front and 1.5 in the rear, but im not sure exactly whats needed to do so.

i know people who use just coil overs to achieve a clean looking drop, would this work for my car just as well for the size drop i want? also how much of a ride difference arewe talking about? much rougher?

will i need new shocks??? to maybe compensate for the rough ride?

and lastly, will i need a camber kit for this size drop?

thanks a bunch.
