Wilwood Aerolite 6R Front Big Brake Kit w/ 14" D/S Rotors & Flexlines – 1995-1998 Nissan Skyline R33 | Red

Unlock the full braking potential of your R33 Nissan Skyline with the Wilwood Aerolite 6R Front Big Brake Kit — a complete, bolt-on front brake upgrade featuring Wilwood’s 6-piston Aerolite radial mount calipers, massive 14-inch Drilled and Slotted rotors, and stainless braided flexlines, all in a striking red caliper finish. Engineered specifically for the 1995–1998 Nissan Skyline (R33), this kit delivers the stopping power, fade resistance, and pedal feel that serious track and high-performance street builds demand — with everything needed for a complete front brake system upgrade in one box.

Key Features:

• Wilwood Aerolite 6R 6-piston radial mount calipers — lightweight, high-rigidity caliper for maximum braking force and pedal feel
• 14-inch Drilled and Slotted (D/S) rotors — superior heat dissipation, gas evacuation, and debris clearing for consistent fade-free performance
• Stainless braided flexlines included — upgraded brake lines for improved pedal feel and safety over factory rubber hoses
• Red caliper finish — durable powder coat for a bold, high-visibility appearance behind the wheel
• 6-piston caliper — three pistons per side for even pad wear and consistent clamping force across the full pad face
• Radial mount design — stiffer caliper mounting for reduced flex and improved brake feel under hard braking
• Complete kit — calipers, rotors, flexlines, pads, brackets, and all hardware included
• R33-specific engineering — bolt-on fitment for the 1995–1998 Nissan Skyline without custom fabrication

Performance Benefits:

• Massively Increased Stopping Power: 14-inch rotors and 6-piston calipers deliver dramatically more braking force than the factory setup — shorter stopping distances and more consistent performance under repeated hard braking
• Superior Fade Resistance: Larger rotor thermal mass absorbs more heat before fade sets in, while drilled and slotted surfaces evacuate gases and debris to maintain consistent friction at elevated temperatures
• Improved Pedal Feel: Radial mount caliper design combined with stainless braided flexlines delivers a firm, progressive pedal with excellent modulation — critical for precise braking on track
• Even Pad Wear: 6-piston configuration distributes clamping force evenly across the full pad face, extending pad life and maintaining consistent braking performance lap after lap
• Flexlines Included: Stainless braided brake lines eliminate the expansion and degradation of factory rubber hoses under heat and pressure, improving pedal firmness and safety
• Lightweight Aerolite Design: Weight-optimized caliper body reduces unsprung mass for improved handling response without sacrificing structural rigidity

• 14-inch Drilled and Slotted rotors (pair)
• Stainless braided flexlines
• Caliper brackets and mounting hardware
• Brake pads
• Installation instructions

Installation Notes:

• Professional installation strongly recommended
• Verify wheel clearance before installation — 14-inch rotors require sufficient wheel diameter and spoke clearance
• Bed-in procedure required after installation — follow Wilwood’s recommended heat cycling process
• Rear brake upgrade strongly recommended to maintain proper front/rear brake bias
• Full brake fluid flush recommended at installation — use a high-temperature DOT 4 or DOT 5.1 fluid

Aerolite 6R Caliper:

Wilwood’s Aerolite 6R is a radial mount, 6-piston caliper engineered for high-performance street and track applications. The radial mount design provides a stiffer, more direct connection between the caliper and upright compared to traditional lug mount designs — reducing caliper flex under hard braking and improving pedal feel and modulation. The 6-piston configuration distributes clamping force evenly across the full pad face, eliminating the uneven wear and inconsistent feel of 4-piston and OEM sliding caliper designs. The Aerolite designation reflects Wilwood’s focus on weight reduction — the caliper body minimizes mass without compromising structural rigidity.

14-Inch Drilled and Slotted Rotors:

Wilwood’s Drilled and Slotted (D/S) rotors combine two proven surface treatments for maximum performance. The slots evacuate gases, water, and debris from the pad/rotor interface, maintaining consistent friction under hard use. The drilled holes reduce rotor mass for lower unsprung weight and provide additional surface area for heat dissipation. At 14 inches in diameter, these rotors provide significantly more thermal mass than the factory R33 rotors — absorbing and dissipating more heat before fade sets in, which is critical for track use and repeated hard braking from high speed.

The R33 Skyline Platform:

The 1995–1998 Nissan Skyline R33 — particularly the GT-R and GTS-T variants — is one of the most capable and celebrated Japanese performance platforms of its era. The R33 GT-R’s RB26DETT twin-turbo inline-six and ATTESA E-TS AWD system make it a formidable track weapon, but as power levels increase and lap times improve, the factory braking system becomes the limiting factor. A Wilwood Aerolite 6R front BBK with 14-inch D/S rotors is one of the most impactful single upgrades available for the R33 — transforming front braking from a bottleneck into a genuine competitive advantage.

Why Wilwood?

Wilwood Engineering has been designing and manufacturing high-performance brake systems in Camarillo, California since 1977. Their products are used in NASCAR, IndyCar, IMSA, and virtually every form of professional motorsport in North America. The same engineering and manufacturing standards that go into Wilwood’s professional racing components go into their street and track performance kits — making Wilwood one of the most trusted names in performance braking worldwide.

Perfect For:

• 1995–1998 Nissan Skyline R33 GT-R and GTS-T builds requiring serious front braking capability
• R33 track and time attack builds outgrowing the factory braking system
• High-power R33 builds where factory brakes fade under sustained hard braking
• Circuit racing and time attack builds demanding consistent, fade-free front braking
• Enthusiasts who want the best available bolt-on front brake upgrade for the R33 Skyline
• Builds seeking a complete front brake system upgrade — calipers, rotors, and lines in one kit

Pro Tip: Always upgrade your rear brakes when installing a front BBK. A significantly more powerful front brake system without a corresponding rear upgrade will shift brake bias heavily forward — causing rear brake fade and potentially unstable braking behavior. Contact us for rear brake upgrade options to complement this front kit.

Note: Verify wheel clearance before ordering. 14-inch rotors require a minimum wheel diameter and sufficient spoke clearance — this is a critical fitment check that must be completed before purchase.
