Overview

Show original supplier description
The Ksport Slimline Big Brake Kit is engineered for Subaru Legacy BL9 models from 2003 to 2009, specifically for the 2.5 GT and Wagon GT trims. This front brake kit addresses the challenge of fitting aftermarket big brake systems with aggressive or factory-style wheels that have limited caliper clearance. Ksport developed the Slimline Caliper to be similar in thickness to OEM single-side piston calipers, allowing compatibility with most factory wheels or those with tight brake clearance. The kit features a forged aluminum caliper that provides a larger brake pad surface area for enhanced braking performance. The Slimline caliper is available in various sizes, suitable for wheel diameters from 15 to 18 inches. This particular kit includes 304mm x 22mm slotted rotors and an orange 3-piston caliper. According to available information, this kit is designed for 2WD vehicles only. Additionally, the product page mentions that oversized items may be excluded from free shipping.
