I recently upgraded my car's brake system with these PROFESSIONAL-GRADE brakes and the difference is astonishing. I no longer have to worry about my automotive stopping power as these brakes offer a noticeably quicker stopping time.Through trial and error I found that these brakes work best with my cars performance profile and offer excellent durability. The only con I can think of is that they are a bit pricier than other options, but the added safety and performance make it worth the investment..
