To provide more consistent stopping during intense wheel-to-wheel races, Fastbrakes was tapped for bigger brakes. 11.7-inch two-piece vented and slotted front rotors are paired up with Wilwood four-piston forged calipers. The rear brakes use slotted 11-inch rotors with Nissan Maxima rear calipers. Fastbrakes also supplied braided steel brake lines to firm up the pedal. An Altima master cylinder, with a 1-inch bore, and a Tilton adjustable proportioning valve make up the rest of the braking system. Performance Friction brake pads, in a 01 compound, grip the rotors and provide the stopping bite. Nismo extended wheel studs are used to hold 17x8-inch Volk TE-37 wheels, which are shod with sticky 235/40/17 Nitto NT01 r-comp tires.
After this Sentra reached the functional roller stage, it was shipped off to Brian Kono at Afterhours Automotive for finishing touch fabrication. Afterhours built a carbon fiber dash for the interior and fitted custom Shields lexan pieces for the windshield, rear, and side windows. All of this work helped to reduce the car's weight down to 2240 lbs. A VIS carbon rear deck was also fitted and reinforced to accommodate an adjustable GTP carbon rear wing. A VIS carbon hood was modified with a large vent to provide a hot air exit for the big Koyo radiator. This top exit vent significantly improved the vehicle's aerodynamics by preventing air from becoming trapped in the engine compartment or from flowing underneath the car where it could create lift. By allowing the air to exit over the top, the vent also allows a greater pressure differential to exist between the top and bottom of the belly pan and splitter, increasing the front downforce.
Afterhours also modified the Stillen front airdam with Dzus fasteners so that it could be easily and quickly removed trackside and added a quick-release belly pan and carbon front splitter to give front aerodynamic downforce. In the rear of the car, Afterhours fabricated a diffuser with vortex generators to give additional downforce with as little drag penalty as possible.
Guardado's goal for this Sentra is to develop it over the next year, dialing in the suspension and the motor package. Keeping in mind the success of its predecessor, we believe that the Dog Car II will have no problem keeping pace. Long live progress.
