A friend of mine said that Racing Dynamic swaybars on my 91 M3 would result a night and day difference when it comes to cornering. My car is used only on streets. I have performed no other suspension modifications. Id like to make the car tighter but am wondering what effect it will have on my daily driving. Will the swaybars make the ride to firm and unbearable over bumps?; or will it just reduce body lean? Any comments on these swaybars pro or con are really appreciated. Thanks alot.
