ACDelco Drilled & Slotted brake rotors were installed on the famous 95 MERC back in 2012, and have performed excellently in all types of driving conditions, regardless of weather and/or number of passengers. Matched these high-performance rotors up with Motorcraft Police Severe Service brake pads to make the perfect combination for long-distance, high-speed touring of the deserts and mountains of the American Southwest. These rotors are GREAT, but they're getting hard to find.
'95 MERC Restoration: I have run these ACDelco Specialty Performance rotors for several years -- over 50,000 miles -- excellent stopping power, with no fade under ANY conditions. These rotors will NOT warp -- they run true and straight. The '95 MERC runs long-distance, hi-speed touring through the deserts and mountains of the Southwest, with trips to Canada and Mexico, too. NEVER a braking problem of ANY kind !! NOTICE: If you experience any kind of shudder, and they tell you that your rotors are warped -- THEY ARE NOT !! I chased a shuddering problem for years -- changed everything -- nothing worked! The ACDelco rotors were not the problem. Or the wheel bearings. Or the Alignment. The problem was eliminated FOREVER by installing Genuine MotorCraft Severe-Service (Police) Brake Pads on all 4 wheels.
Why in the hell don't you folks offer this "Enhanced" braking to the general public when building your GM cars? I'm about to replace the 3rd set of AC Delco warped rotors on my wife's 2012 Impala that currently has 53,000 miles on it. I may have to go after-market as you folks obviously out sourced your rotors from the get go
The guy that's telling you that your rotors are warped is WRONG !! The ACDelco Specialty Performance rotors need to be paired with Severe-Service (Police) Brake Pads. The high metallic content of the cop pads works better on the cop rotors. I used MotorCraft Police pads -- from Amazon.com. They don't offer these rotors on stock cars because of the extra expense -- these are TRICK rotors, dude !!
