Shown here in IS 350 form, the package includes a toughened-up body-kit, with new bumpers at both ends, low-slung side skirts and a small lip spoiler at the rear.
There's also 19-inch aluminium wheels and a sports exhaust setup, while handling enhancements include sports dampers and extra bracing below.
Power and performance figures remain unchanged, with the new IS range powered by a 154kW 2.5 V6 and a 233kW 3.5 V6. A new IS 300h hybrid is also available, offering 162kW and 4.3 l/100km fuel consumption figures.
The TRD kit is available only in Japan for now, and Lexus lists a price tag of around $12,000 for the full pack. The parts will also be offered separately, however.
The new IS range will hit Australia in the third quarter of this year, including the hybrid model.
