Wilwood FSLI4 Front Hat Kit 13.00in 2003-05 Scion xA xB

Wilwood's FSLI4 front brake kit brings forged Superlite four-piston calipers and oversized 13-inch (12.88-inch actual) rotors to the 2004-2006 Scion xA, 2004-2006 Scion xB, and 2000-2005 Toyota Echo. This is a serious step up from the factory single-piston setup on these compact cars, adding substantially more pad area and clamping force to the front axle.

The forged Superlite caliper has roots in competition use, but Wilwood has made it adaptable for street applications as well. Lug mounting and a full range of piston sizes allow it to fit platforms with specific mounting and piston volume requirements. The FSL design gives you a caliper that works both on the street and at the track, with the rigidity and heat management that comes from a forged body.

At 13 inches, the rotors are significantly larger than stock, which increases the thermal mass available for absorbing heat during repeated hard stops. That translates to better fade resistance when pushing the car on a track day or aggressive canyon driving. The larger swept area also means the pads work more efficiently, spreading wear more evenly.

Options for caliper finish and rotor design let you configure the kit for the look and function you want. Whether you are building a Scion xB for autocross or improving the braking on a daily-driven Echo, this kit gives you a meaningful improvement in stopping power from a well-known name in racing brakes.
