If you owned the Wrangler you should switch to TeraFlex performance Big Rotor Kit. This is because it the advanced version of the wrangler with much better braking performance with 33 to 35in tires. With this feature the brake pads and the brake calipers will all be retained. The rotor diameter is however increased to 13.3 inches from the original 11.9 inches. The increased diameter allows for much better breaking so that the distance covered when breaking is reduced significantly. This can simply be explained by the fact that with a much larger diameter of the rotor the much more stopping power it has which in turn translates to a shorter braking distance. This installation does not require that there be modifications of the brake line. The best thing is that you can simply install them yourself with basic tools.
