i just bought a 2001 audi a6 4.2 with 55,000 miles and the car needs front brakes. the rotors are extremely worn and brake pedal travel is long. any good replacements besides oem and big brakes kits? i bought it at auction and think i might have also bought myself a huge expense. i would be really interested in something like slotted or zimmerman cross drilled. i have been driving a 98 bmw m3 for 4 years.
