Wilwood Red Front Superlite 4 Kit with 12.88-inch GT Slotted Rotors — Scion xA / xB 2004–2006, Toyota Echo 2000–2005

GT-slotted discs accompany red four-piston calipers for the specified Scion xA, xB and Toyota Echo. At the front axle, this kit pairs red powder-coated 4-piston calipers and 12.88-inch GT-slotted rotors with the mounting hardware for Scion xA / xB and Toyota Echo. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. It designs and manufactures disc brake systems for motorsport, street-performance and specialized applications, with a range including calipers, rotors, master cylinders, valves, fittings and brake lines. Selecting the mounting and hydraulic components together is part of building the complete brake system.

Technical Details

• Manufacturer part number: 140-8335-R.
• Rotor dimensions: 12.88 in; 327.15 mm diameter x 1.10 in; 27.94 mm thick.
• Rotor construction: Spec-37 Iron; vented; GT Slotted friction surface.
• Wheel-size guide: 17 in; 431.8 mm minimum nominal diameter; verify actual template clearance.
• Calipers: 4 pistons; forged aluminum; stainless steel pistons.
• Caliper attachment: lug mount; 1/8-27 NPT hydraulic inlet.

• Rotor/hat wheel-stud clearance patterns: 4 x 3.93 in.
• Rotor/hat stud-hole clearance diameters: 0.520 in; 13.21 mm. These are hole sizes, not wheel-stud thread specifications.
• The rotor/hat drilling does not change the vehicle hub or axle wheel bolt pattern.
• Sold as one kit. Mounting hardware is included. Hubs are not included.
• Brake pads are included; use the compound and installation instructions specified for this rotor package.
• Spindles, master cylinder, brake booster and hydraulic brake lines are not included.

Package and installation requirements

• Front hose kit 220-8336 is not included.

Fitment & Compatibility

The four-lug applications are 2004–2006 Scion xA, 2004–2006 Scion xB and 2000–2005 Toyota Echo. A later model carrying a similar name is not covered by these specific entries. The kit’s actual rotor diameter is 12.88 inches, verified by DS472 and the current rotor specification, with a 1.10-inch-thick vented Spec-37 disc. The four-piston Superlite package requires more wheel room than the factory assembly; its catalog guide starts at 17 inches and still needs a spoke-and-barrel template check. Existing hubs are retained, so verify their mounting surfaces and four-lug arrangement before assembly. Rotor-hat drilling cannot convert a different hub pattern. Wilwood’s separate front line kit must also be matched and routed for the installed suspension.

The listed applications below retain their equipment qualifiers. Check the matching row and each referenced note before selecting the kit.
