This GR Yaris Circuit Pack gets thoughtful touches that enhance its rally-ready spirit: a mirror riser for better sightlines, under-seat Helix sub for trunk-free bass, and a Turbosmart dual-port BOV for that snappy blow-off tone. H&R lowering springs tidy the stance and sharpen response without killing compliance. The vibe is playful and practical — accessories that respect the car’s hot-hatch roots while making daily life better. Minimalist, purposeful, and loud when you want it to be 🎯
