Porsche delivers these cars with the front and rear ARBs set to the middle position.  Potential interference between the brake line fitting and drop links becomes more likely to occur as: The anti-roll bar is adjusted towards the softest setting (the hole closest to the end of the bar) The steering wheel is turned towards full lock The suspension is under full droop (extended as far as possible) To address this clearance issue, AP Racing has developed the following solution: Relocate the caliper hydraulic connection from its current position to the lower bleed screw.  This requires a new Spiegler brake line of a different length with a new banjo bolt design manufactured by Spiegler. The original inlet port in the center of the AP Racing caliper will be closed off with a plug. CP9661 Kit, part# 13.01.10141/13.01.10141-ENP On our CP9661 front caliper kits in the as-delivered configuration (brake line attached to the inlet port in the middle of the caliper), interference between the drop link and the brake line fitting may occur when the ARB is adjusted to the softest setting as you approach full steering lock and full suspension droop.   If you won’t be running the ARB in the softest setting with our CP9661 kit, you should not anticipate any issues, and you should not expect any interference when the ARB is set to the medium or stiff settings.  If you do plan to run your front ARB in the softest setting, we suggest implementing our brake line relocation as described above, which will provide adequate clearance in all ARB settings. CP9669 Kit, part# 13.01.10142-ENP The wider calipers in our CP9669 kits extend further into the wheel well, which creates more potential clearance issues.  With the brake line attached to the center inlet port and the ARB set in the soft or middle settings, there may be interference between the brake line banjo fitting or the caliper body with both the ARB drop links or the ARB itself. With the brake line relocated to the lower bleed screw port, the CP9669 calipers have adequate clearance with the front anti-roll bar end links when they are set in the middle or stiffest positions.  The caliper will not clear the front anti-roll bar adjusted to its softest setting, so the ARB cannot be run in that setting.  Under full droop and full lock, the end of the anti-roll bar itself may make minor contact with the inlet port plug, but the likelihood of putting the components in those positions under normal driving conditions is very low.

Fitment: Chevrolet Corvette C8 Z06 Front with Factory Cast Iron Rotors For the Corvette C8 Z06 with factory Z07 carbon ceramic rotors, see Girodisc A1-320. This Girodisc two-piece floating rotor system is a direct replacement for the OEM cast iron brake rotors on the C8 Z06 Corvette. The Girodisc two-piece rotors will bolt directly to the C8 Z06 and work perfectly with OEM calipers. By upgrading your C8 Z06 brakes to these lightweight, high-performance replacements -- as opposed to a big brake kit -- your factory brake bias is maintained as well as your ABS efficiency. These Girodisc rotors are lighter than OEM pieces, reducing rotational and unsprung mass for quicker acceleration, sharper suspension response, and better brake feel. When used with Pagid or PFC high-performance brake pads and Competition Motorsport RF1 racing brake fluid, this Girodisc rotor system gives you an amazing solution to overheating, cracking and warping rotors. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The rotor itself is manufactured from a proprietary cast iron, domestically sourced and made to the same specification used by professional racing organizations. The rotor's curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc. The rotor and hat are joined by a floating mount system utilizing 8-10 high strength alloy steel drive pins manufactured by Girodisc in-house, then cadmium plated for corrosion resistance. The alloy drive pins transfer breaking load while maintaining axial and radial float between the disc rotor and hat. The pins are secured by Grade-12 cap screws and hardened washers, mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise typically associated with floating rotors. The two-piece Girodisc design allows for rotor-ring replacement as well, minimizing future replacement costs while delivering outstanding performance and cooling. Priced/sold per pair.
