I've got Tein Coilovers, and I'd recommend them as they're ride height adjustable as well as 16 way damping adjustable but if you're going cheaper, I've heard that KYB AGX shocks are decent for the money. For coilover sleeves Ground Controls with Eibach springs, Skunk2s and HP Racing are the most popular. Going one higher on the shocks would get you Tokico Illumina 5 way adjustable.

I find it's really helpful having damping adjustability, since the ride quality can vary greatly, and I'd get sick of getting around on rock hard shocks for daily driving. There's a fine line between rock hard and really bouncy, and it's good to be able to balance the two properly.
