you want real coilover as in FULL coilover system (includes threaded shocks and springs) or cheaper sleeves coilover such as Ground Control?

I suggest you get a good system, at least Ground Control + Koni yellows, or a Full coilover system or else, you'll sacrafice the performance and comfortability of the car and will end up fawking up the whole car in couple months. Suspension is the most important part. So basically, a setup under $600 bucks will not be good.

So if u need a hook up, let me know, I can get u some for cheap. Send me a PM, I don't check threads often.
