The combination of 380 x 34mm front rotors, 380 x 30mm rear rotors and application-specific hats and brackets keeps the package focused on the demands of a serious track build.\u003c\/p\u003e\u003cp\u003eThe choice of caliper finish also determines the front caliper family: the anodized system uses CR6420 front calipers, while the ENP system uses CAR8949Y55 fronts. Both retain a four-piston rear layout. The complete kits are offered without pads, allowing you to select the friction material appropriate to your car and use.\u003c\/p\u003e\u003ch2\u003eA Complete Front and Rear System\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFront: six pistons, 27.0 \/ 31.8 \/ 38.1mm piston diameters\u003c\/li\u003e\n\u003cli\u003eRear: four pistons, 31.8 \/ 34.9mm piston diameters\u003c\/li\u003e\n\u003cli\u003eFront rotors: 380 x 34mm, 48 ventilation vanes\u003c\/li\u003e\n\u003cli\u003eRear rotors: 380 x 30mm, 48 ventilation vanes\u003c\/li\u003e\n\u003cli\u003eFront caliper weight: 7.3 lb each; rear: 6.0 lb each\u003c\/li\u003e\n\u003cli\u003eFront rotor weight: 21.6 lb; rear: 15.7 lb\u003c\/li\u003e\n\u003cli\u003eApplication-specific non-center-lock hats, caliper brackets and mounting hardware\u003c\/li\u003e\n\u003cli\u003eBrake line references provided for both axles\u003c\/li\u003e\n\u003cli\u003eBrake pads sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCalipers and Pad Loading\u003c\/h3\u003e\u003cp\u003eThe front six-piston and rear four-piston arrangements use staggered piston diameters to distribute load along the pads.
