N2OInferno said:They help. Any time you lower your car man it's gonna be bumpier. Springs or coilovers. It's just a fact of life unless you get some of those "comfort" springs that have lower rates.
As for coilovers, I'd say these aren't bad. Probably not as harsh as Tein or JIC, but they DO make it handle and feel kinda like a go-kart with limited suspension.
And by bumpy I mean, if you go over a big bump, you'll definitely feel it. Small bumps don't do much though, and highway driving and the like..
