This is the ultimate front brake kit for your Cadillac ELR and Gen 1 Chevrolet Volt featuring 12.6" rotors and 4 piston ZZP calipers. The stock brakes feature an 11.8" rotor on the Volt and single piston sliding calipers on both the ELR and Volt. 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) 12.6" rotors
• Powerstop Z17 Brake Pads
• Caliper Pin Kit
• Copper crush washers
• 10mm hubcentric wheel spacers (5x115 - 70.3 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. Slight trimming of the stock dust shield will be needed. 

Test fit with stock ELR 20" wheels. Have not verified with any other OEM wheel combo. Likely will not fit 16" wheels. Verify wheel in rotational movement before final installation; a larger spacer may be needed with non-OEM wheels. Caliper protrudes 42mm from the rotor face towards the outside of the wheel. If you have any questions about wheel fitment before installation please email customerservice@zzperformance.com.

These kits are made to order. 

Fits: 2014-2016 Cadillac ELR and 2011-2015 Chevrolet Volt
