These are great! looks better and the calipers wont rust.stopping power is increased about %30 more then stock.went on easy but you must know what your doing when putting these on.Cons are if u cant find the 93 cobra rear end or the break proportioning valve for the 4 disc conversion you will be very disappointed and they will not work without it.they say there is a way to modify or rig it with some other parts that cost you more money and more modification time and personally I would not buy these unless you have that 4 disc valve if you want it done right.Other then that they are very beautiful on my 89 5.0 lk

Yes, I would recommend this item to a friend!
