This is the ultimate front brake kit for your Gen 2 Chevrolet Cruze featuring 12.6" rotors and 4 piston ZZP calipers. The stock brakes feature an 10.86" rotor and single piston sliding calipers, which is a known pain point of the Delta II platform. The key to better braking performance comes with larger rotors, larger pad contact patch, and better heat distribution of fluid; this kit addresses all of those areas. Larger pad surface area = increased braking performance and reduced brake fade. Not only does this kit drastically improve your braking performance, they also look great compared to stock calipers!  Kit includes: (2) 4 piston ZZP calipers (2) Custom drilled 12.6" rotors Powerstop Z17 Brake Pads Caliper Pin Kit Goodridge Stainless front brake lines Copper crush washers 10mm hubcentric wheel spacers (5x105 - 56.5 center bore) (10) ARP extended wheel studs Installation note: Due to the increased size of the caliper a wheel spacer (included) is needed for installation. To verify that you have enough stud engagement on the lug nut we include extended wheel studs. You WILL have to remove the front wheel bearings to extract and install the new extended studs. Test fit with stock RS 18" wheels. Have not verified with any other OEM wheel combo. Likely will not fit stock 16" wheels. Verify wheel in rotational movement before final installation; a larger spacer may be needed with non-OEM wheels. These kits are made to order. This kit uses the common Cadillac ATS/CTS front pad shape so replacements can be found at local parts stores or online. Fits: 2016.5-2019 Chevrolet Cruze 1.4L
