If pro kits are a large enough drop for you, that would be my recommendation. THey are not too expensive, no need for camber kit, and you should have no trouble if you are staying with the stock shocks.
The biggest think is ride quality with these springs. I'm pretty amazed. My car rides better than any lowered car i've been in. It actually rides better than stock. It's a tiny bit too bouncy but nothing that bothers me. That's from the stock shocks though. I find my brothers stock outback to have a harsh ride compared to my car and his car is totally stock, well who mods and outback, lol. And no squeaks, rattles, etc. The handling is most defineatly improved over stock as well. This is a pretty much no comprimise setup. All good, no bad, no tradeoff.
