Understeer occurs as you meet and pass the limit of adheasion of your tires. Before that (for a street car) you are likely just trying to limit body roll. If you aren't on a track or trying to run your car to 10/10ths on the street,Uuc,HR,turner bars,all will be fine. I prefer UUC myself,and definatly replacing the Links. The added stress the bar will see make quick work of aging oem links. When your car clicks over light hits or speed bumps its time for another pair.
