For a set of large-scale multi-piston brake caliper can directly improve the braking performance (and improve the car's ratings - of course, crankshaft with the perspective type of wheels you). The reason is simple, big brake calipers, brake pads are equipped with a total area too big, of course, like the brake effectiveness.

Change the car industry seems to attach great importance to the number of piston brake caliper, piston course, the more uniform pressure applied to the brake pads and the temperature of the produce, crankshafts for sale but also increase the total area of the piston. Increased piston area what good is it? Because brake oil pipe can withstand the pressure of limited area can be improved to increase the piston brake disc brake pads for the ultimate pressure (pressure = pressure × area). But switching to multi-piston calipers in the rear brake pressure to achieve the same may require more pedal travel, that is to step deeper. Way to improve is to replace the brake master cylinder, and even equipped with dual brake master cylinder racing style to control the distribution of the front and rear brakes in order to achieve the most ideal of personal effects, but this conversion cost is very high, one more multi-piston calipers in the more expensive price, the second is modified brake master cylinder, especially a lot of knowledge involved in dual brake master cylinder, and spend a lot of time and materials, if not modified race car is really not worth it.

From a practical point of view to consider, choose matching calipers or to emphasize the general high performance street car with four-piston calipers will suffice. Also worth noting is the weight of the brake caliper, although the shape is similar, but with a light metal fabrication of high-end brake calipers (eg APRacing, Brembo, etc.) lighter than the cast iron products more than doubled, while the brake system is non-spring load (unspringweight) of one part of the car's handling much weight but have a direct impact. In addition, the thermal performance of a very high-grade brake calipers, brake system to control the temperature of great help.
