Wilwood Forged Superlite 6R Front Big Brake Kit (Race) – Honda S2000 | 12.88" GT Slotted Directional Vane Rotors | FSL6R/ST 6-Piston Thermlock Calipers | BP-30 Race Pads | Stainless Braided Lines

The Wilwood Forged Superlite 6R Front Brake Kit (Race) for the Honda S2000 is a complete competition-grade front big brake kit configured for unrestricted class road racing with 17" or larger wheels — delivering championship-proven braking performance through Wilwood's FSL6R/ST six-piston Thermlock calipers, 12.88" directional vane GT competition rotors, BP-30 high friction race compound pads, and stainless steel braided flexlines. These proven winners have delivered championship performance in road racing's most gruelling production car categories. The Honda S2000 (AP1/AP2) is one of the most celebrated front-engine, rear-wheel-drive sports cars ever produced — a platform with a dedicated road racing and track day community where braking performance is a critical competitive variable. Wilwood Engineering is the most respected performance brake manufacturer in the North American market — an American manufacturer with decades of motorsport development experience across road racing, oval, drag, and off-road competition.

Key Features:

• FSL6R/ST six-piston Thermlock calipers — Wilwood's Forged Superlite 6R/ST calipers with Thermlock pistons — six-piston monoblock caliper design for maximum clamping force and pad contact area — Thermlock pistons insulate the brake fluid from caliper body heat to prevent brake fluid boiling under sustained race use
• 12.88" GT competition rotors — 12.88" directional vane GT slotted competition rotors — directional vane internal cooling for maximum heat dissipation under sustained race braking — GT slotted surface for consistent pad bite and gas/debris evacuation
• Dynamically mounted rotors — rotors are dynamically mounted to forged aluminium hats — the dynamic mounting allows the rotor to float slightly on the hat, reducing thermal stress and rotor warping under sustained race heat cycling
• Forged aluminium hats — lightweight forged aluminium rotor hats — reduced unsprung and rotating mass compared to cast iron hat alternatives
• Radial mount brackets — radial mount caliper brackets secure the calipers to the OE location without modification — direct-fit installation using the factory caliper mounting points
• BP-30 high friction race compound pads — Wilwood's BP-30 high friction race compound brake pads — engineered for sustained race use at elevated temperatures where street pads fade — correct pad specification for unrestricted class road racing
• Stainless steel braided flexlines — premium stainless steel braided brake flexlines replace the factory rubber hoses — reduced line expansion under pressure for more consistent, firmer brake pedal feel
• Race configuration — configured for unrestricted class road racing with 17" or larger wheels — the correct brake kit specification for competitive S2000 road racing
• Championship proven — Wilwood's Forged Superlite 6R kits have delivered championship performance in road racing's most gruelling production car categories
• Wilwood quality — manufactured by Wilwood Engineering, the most respected performance brake manufacturer in the North American market

FSL6R/ST Calipers — Thermlock Technology:

Wilwood's Thermlock piston technology is a critical feature for sustained race use. Under repeated hard braking, the caliper body absorbs significant heat from the rotor and pads — this heat is conducted into the brake fluid through the caliper pistons, raising fluid temperature and risking vapour lock (brake fade caused by boiling brake fluid). Wilwood's Thermlock pistons use a phenolic or titanium insert that insulates the brake fluid from the caliper body heat — maintaining lower fluid temperatures under sustained race braking and significantly reducing the risk of vapour lock. For S2000 road racing applications where sustained hard braking is a constant, Thermlock pistons are a critical safety and performance feature.

12.88" GT Directional Vane Rotors — Competition Design:

The 12.88" GT competition rotors use a directional vane internal cooling design — curved internal vanes that act as a centrifugal pump, drawing cool air through the rotor from the hat to the outer edge as the rotor spins. Directional vane rotors provide significantly better cooling than straight vane alternatives under sustained race use — maintaining lower rotor temperatures for more consistent braking performance and longer rotor service life. The GT slotted surface provides consistent pad bite across the full pad face and evacuates gas and debris from the pad/rotor interface for consistent friction coefficient. The dynamic mounting to forged aluminium hats allows the rotor to float slightly, reducing thermal stress and the risk of rotor warping under the extreme heat cycling of race use.

S2000 Road Racing — Why This Kit:

The Honda S2000 (AP1/AP2) is one of the most popular platforms in production car road racing — a lightweight, balanced chassis with a high-revving naturally aspirated engine that rewards driver skill and chassis setup. In a road racing context, the S2000's factory brakes are quickly overwhelmed by the sustained braking demands of a race circuit — fade, inconsistent pedal feel, and rotor warping are common issues on track-prepared S2000s running factory or street-grade brake components. The Wilwood Forged Superlite 6R Race kit addresses all of these issues with a purpose-built competition brake system — six-piston Thermlock calipers for maximum clamping force and fluid temperature control, directional vane GT rotors for maximum heat dissipation, BP-30 race pads for consistent high-temperature friction, and stainless braided lines for consistent pedal feel.

A brake system upgrade of this magnitude requires brake bias adjustment and a complete brake system evaluation. Professional installation by an experienced race brake specialist strongly recommended. BP-30 pads require a proper bedding procedure before race use.

What's Included:

• Wilwood FSL6R/ST 6-piston Thermlock front calipers (pair)

• Radial mount caliper brackets (pair)
• BP-30 high friction race compound brake pads
• Stainless steel braided brake flexlines
• Premium grade hardware

Installation Notes:

• Professional installation by an experienced race brake specialist strongly recommended — a competition brake system of this specification requires correct caliper alignment, correct rotor hat torque, correct brake line routing, and a complete brake system bleed and evaluation before race use
• Verify wheel clearance before installation — measure caliper and rotor clearance with your specific wheel and tyre combination — minimum 17" wheel required
• BP-30 pads require a proper bedding procedure before race use — follow Wilwood's bedding procedure to correctly seat the pads to the rotor surface before subjecting the system to full race loads
• Brake fluid upgrade recommended — use a high-temperature race brake fluid (DOT 4 or DOT 5.1 with a high dry boiling point) to complement the Thermlock pistons' heat management capability
• Brake bias evaluation required — a significant front brake upgrade changes the front/rear brake bias — evaluate and adjust rear brake bias to maintain correct brake balance for the S2000's weight distribution
• Directional rotors — verify correct left/right rotor installation — directional vane rotors must be installed on the correct side for the vanes to pump air in the correct direction
