Brembo one of the worlds premiere brake specialist companies has really hit the nail on the head with their OEM styled rotors. The common problem on the WJ especially with the early styled calipers has been extreme shaking due to rotor wear. While the cause has been debated as heat or poor caliper wear, one thing remains the same, eventually you need new rotors. The OEM Jeep rotors are made from two pieces of steel while the Brembo's are made from One. This is said to cool more evenly although I believe that warping is not 100% heat related.
Enough talk. These Brembo rotors work extremely well. Their not high performance or anything but after I replaced my calipers with the new style Jeep ones and still had warpage I decided I needed to get rid of the Jeep Rotors. These brembo's costed less than OEM stock and they were easy to install and work great.
They have lasted more than twice as long as my last set of OEM stock rotors and still have yet to warp. Even if they did I'd purchase them again due to cost alone.
Cost Effective replacement for OEM stock rotors
Warpage resistance appears to exceed the stock rotors.
Great factory support, and expertise.
