Is there really a point? My 300E has the single piston floating calipers, and it will drag the car from 70+ to 0 in no time with practically no effort at all (as do the twin piston calipers on my W126)......both will lock the tires instantly as well if you hit them hard, so what advantage do the 4 piston brakes have unless you have bigger rubber on the road? Perhaps in sporting event driving.....but for normal use?
