I think the ultimate question is what do you plan to do with your car and how much you are willing to spend.
I was actually pinging folks here for coilovers for my Supra. Though 2K for some KW V3's seems fair, I can't justify it since I won't be tracking my Supra.
But if you want an entry level coilover that won't break your wallet, I would suggest talking to these guys. Ain't nothing wrong with the lower tier stuff if you have good valving and Swift springs.
