THE HKS

The Dimension Y philosophy begins with air and response. A full cold‑air intake kit feeds the G16E‑GTS, while the SPECIAL FULL TURBINE KIT with GT4950_BB ball‑bearing turbocharger and Super SQV IV blow‑off valve delivers a surge of boost that is immediate yet controllable, bringing output into the region of 400 ps. Exhaust flow is managed by a Super Turbo Muffler Ti and HKS‑spec metal catalytic converter, combining motorsport‑grade efficiency with a refined, rally‑inspired tone.

Electronics are layered over the OEM ECU using Power Editor R, an additional injector driver and EVC7 boost control, supported by AF Knock Amp 3 for real‑time safety. A 295 L/h fuel pump and HKS‑spec 750 cc additional injectors provide the headroom needed for serious circuit work, while the HKS intercooler kit, S‑Type oil cooler and transfer oil cooler maintain stable temperatures under sustained load.

HIPERMAX R dampers in THE HKS specification, combined with ADVAN A050 tyres on 18×9.5J ADVAN Racing GT BEYOND wheels, sharpen the GR Yaris’s already aggressive turn‑in and traction. ENDLESS monoblock calipers and rotors deliver consistent braking feel, confidence‑inspiring even on long downhill stages. The BODY KIT TYPE‑S with HKS front diffuser and rear wing balances downforce and drag for high‑speed stability. Inside, BRIDE ZETA IV fixed bucket seats, HKS harnesses, a NARDI Sports wheel and bespoke interior trim create a cockpit focused on serious driving. THE HKS GR YARIS Gen2 Dimension Y realises the sweet spot of a ~400‑ps turbocharged AWD compact—the place where every surface, every condition and every lap becomes an invitation to drive harder.
