I see a lot of posts in here recommending coilovers that have more adjustability than most people would need on the track... What's your budget OP? BC Racing, D2 Racing, Tanabe, and Megan are decent. Tein has several good choices. KW V3 is good, but is a waste of money if you're not going to use all the adjustability. Springs will get you the drop, but you don't have the adjustability.

Shoot me a PM with your budget and I can make some recommendations.

KW v3 would be the best setup. There are cheaper options out there, but lower performance and component quality.

Imo, lowering springs with stock shocks are a bad idea because of the limited bump travel. Shortened shock bodies would be the way to do it right. However, oem shock valving does seem to work ok with Swift springs.

Swift engineers their products very well to match the valving and shock stroke of OEM shocks.

Im in the same boat as this dude.. I don't track my 370 at all and I really want to lower it from stock.. I've read all about how good the Swifts are but they don't quite lower the car as much as id like... I'm thinking on Megans... Megan is good for streets right? Any good prices? I see them on ebay for $850

If you hit the twisties and like spirited driving KW3s are worth every penny
