R1 Concepts 2017 - 2019 Camaro ZL1 (V8) REAR GEOMET Drilled Rotor Set #2R1719ZL1-GD

R1 Concepts Carbon GEOMET® Series Cross-Drilled Rotor
Cross-Drilled and Diamond Slotted rotors provide the maximum benefits in stopping power, durability and performance

Best for: Street Performance
Handling a vehicle properly on the road means that you sometimes need to stop on a dime. The R1 Concepts GEOMET Carbon Series is first and foremost about performance.

Pros:

• If you live in an area that experiences a lot of rain, drilled rotors are a very good choice. They perform well in rainy climates by offering a good “wet bite,” hold up well over the life of the rotors, and deliver more friction and more bite than their slotted counterparts. The bite is better with these brake rotors because the drilled holes give the water a place to escape, thus drying off the braking system components when water is present. Less water means a better bite and improved brake rotor performance.

Cons:

• While drilled rotors have a lot to recommend them, they can wear unevenly and may develop cracks when used in racing vehicles due to the heat and temperature extremes of a race. Drilled brake rotors also tend to wear in concentric grooved styles, which can look funny when the rotors are aged if the drilled hole patterns are not staggered. While this does not impact the performance of the brake rotors, it can affect the vehicle aesthetic and sensitive drivers may prefer to select a different style of brake rotor or else change out their rotors more often.
• Drilled rotors are also a poor choice for race cars under the most extreme conditions. They cannot withstand repeated heating and cooling cycles very well, and will fail sooner rather than later as a result of these extreme conditions. Drilled brake rotors are fine for general use in street vehicles.
