Born from 100's of hours and almost 4000 laps of racing in the American Endurance Racing series, the ultimate Silvia/180sx/240sx/S-chassis big brake kits mean business. Intended for serious track duty and/or those wanting to look baller, these kits offers better bang for your buck than anything on the market, all while being able to keep Z32 parking brake functionality.  These are the same kits used on the Core4 S14 VQ swapped endurance race car with excellent results.
 
Front Big Brake Kit
Like none other on the market, you have the ability to run 3 different rotors depending on your application.  Utilizing the latest iteration of Wilwood's Forged SuperLite brake caliper series, the "FSL6R," the Core4 caliper adapter bracket allows the choice to run a standard 1-piece Z33 350Z track model rotor for budget minded enthusiasts, or for those looking for more thermal capacity and cooling efficiency, a 332mm x 32mm rotor ring mounted on Core4's rotor hat, or for big game hunters a 355mm x 32mm (18" wheel minimum).
 
2-piece rotor designs keep significant heat away from the wheel bearings (300F+ differential measured from rotor to hat coming off track) and also reduce rotating, unsprung weight.  The Core4 332mm x 32mm rotor setup is more than 3lbs lighter than a Z32 front rotor and more than 6lbs lighter than a Z33 track rotor.  These are significant weight savings with much greater thermal efficiency!   
 
 
Rear Big Brake Kit
 
Utilizing the same rotor hat as the front kit with a 327mm x 21mm rotor ring, the Core4 kit rear is truly bolt on and doesn't require cutting anything off your uprights in order to make clearance for fitment like most other rear kits do. This allows it to work on most aftermarket rear uprights (confirmed GKTech rear upright), making it possible for drifters to run an insane dual FSL4R caliper setup!
 
Like the front, the rear also uses Wilwood's newest Forged SuperLite Radial mount calipers, but a 4 piston configuration (FSL4R) that is perfectly balanced with the front.  That means the brake pad shape is the same for the front and rear in these kits.  When running an external proportioning valve, it is possible to run the same pad compound front and rear and keep inventory simple!
 
A truly unique feature unlike anything else on the market is the ability to retain a functional Z32 parking brake setup.  This is achieved using an optional (and removable) Type III, Class 2 hardcoat anodized aluminum drum.  The rotor assembly with modular parking brake drum is 3lbs lighter than a Z32 rear rotor for reduced unsprung mass with greater thermal capacity and efficiency!
 
The Core4 Rear Big Brake Kit is perfectly balanced when paired with our Front Big Brake Kit and used with a Z32 brake master cylinder (not included). Rear kit must be installed with a larger front brake kit to keep proper balance!
