if i remember correct i think there is 2 different anti roll bars for the 3 door as the early ones had the wheel slightly further back but was a bit twitchy so another roll bar was used that pushed the wheel forward slightly helping the handling, i think they are number'd to tell what one you have.

Iv never had issues with my handling but front and rear strut braces definately helped as did the coilovers so mine probably isn't a good comparison as not alot standard anymore.
