Had to replace the rears at 15,000 miles the fronts are still totally fine at a 19,600 miles !
It is because of the weight balance of the car being rear heavy, I think it is 60 /40 ? when cornering hard most all of the pressure is going on the big fat rears that are supplying the power where as the fronts are more of a guide rudder. I am not even seeing the wear bars on the fronts and fully expect them to hit + 20,000 miles
It also depends on if you have the AD07 (which i have )or the A048s which don't last very long at all
That said you will also notice that your front brakes/pads wear much quicker than the rears for exactly the same reasons, when you are braking hard, all the pressure goes to the fronts, I had to get new front pads at 15,000 miles and the rears are still fine at 19,600
