I am very happy with these brakes. Not only do they stop my 2011 Challenger quicker and smoother than the factory brakes, they also look fantastic through the wheels. I installed them and did the recommended break-in. I live in a large metropolitan area and have to commute to and from work every day, which means I have to deal with traffic jams on the freeway. The day after I installed these brakes someone decided to crash and traffic went from 65-70 speeds to a complete standstill. I had just pulled into the far left (passing) lane and suddenly stumbled over stopped cars. I hit the brakes and the ABS kicked in immediately. My car stopped very quickly and avoided a collision. I used to have to step on the brakes and in these conditions (dry road, warm weather) the ABS never worked because the tires didn't lock. Serious upgrade!
