Fitment & Compatibility

Check the exact WRX trim before comparing the original rear hub and upright with the instructions. Verify parking-shoe condition and cable movement rather than assuming those retained parts are renewed by the kit. Set rotor and caliper position as directed, then adjust the parking brake for full release. Use the complete wheel diagram to check barrel and spoke clearance. Route the hoses through suspension movement and assess hydraulic proportioning with the front brake package.
