You will get a lot of opinions here on this. If you're only on a track once a month, I would get a more streetable kit. I wouldn't lower it more than 1 inch. By streetable kit, the Hotchkis track pack would do the job. Eibach makes great stuff too. For the price, you can't go wrong with either. Detroit Speed's kits are also very streetable, but cost more.
I would stay away from Pedders unless you are racing regularly. They have great stuff, but they are definately more of a purpose built track package. Great on the track, might even be the best, but you will pay the price on daily driving. My usage is similiar to yours and I'm going with the Hotchkis track pack. In the end, it really depends on how much of a tradeoff you are willing to make on daily driving comfort for track performance. Good luck to you...
