I recently upgraded my automotive brake system with a set of drilled and slotted rotors and I`m very pleased with the results .My analysis of this product showed that it not only improves the overall performance of my car, but adds a sleek look to my wheels. The slotted design allows for better heat dissipation, leading to less brake fade and more efficient stopping power. The only con I have is the price, as they do come with a higher price tag than traditional rotors. Nonetheless, the added durability and performance make it worth the investment..
