how much different is there with an eibach front sway bar that is 24.5mm and stock 02 ls sport 22 mm sway bar with poly end link. just considering be for i buy is set of front and rear sways bars.
The difference you feel will depend on what other supporting suspension mods you have done.
installing them as a set will make a more noticeable difference than just the front IMO. Adding the set to my car was a big difference, especially when i got in my buddies cav with no sway bars.
I have a k brace for sale. its brand new, i was just to lazy to install it and now my car is a show car only so i would be willing to hook you up cheap! PM me for more details.
Go with the Addco sway bars. Eibach is actually made by Addco and is just branded and more expensive. www.neverenoughauto.com These guys have the best deal and customer support.
