I'm looking to get a set of coilovers for the z, but I dont know the difference in them all. I know some are made for track/street etc. All im looking for is a good drop, lower the better. I also need them to be easily adjustable. I can't ride dumped all the time because the roads here are awful. I will never track the car so I'm just looking for a big drop when I go to shows. Any help would be great.

+1, there's even a sticky with a really good comparison.
Go with KW V1's, basic stance or BC's will do too
