The highlight of Toyota’s booth at the Tokyo Auto Salon has been the facelifted GR Yaris but it also brought along with it a pair of modified GR Yaris and GR Corolla models that show just how mean the duo can be made to look with some visual alterations.

Starting with the smaller of the two models is the GR Yaris RR x GROW Concept. It has been outfitted with several parts from Rookie Racing that add to its aggression, including a dramatic front splitter. Additionally, Toyota has equipped it with a set of silver wheels with purple lug nuts and a pair of side skirt extensions.

Changes continue at the rear where there is a new lip attached to the bumper, titanium exhaust tips, and a towering rear wing perhaps inspired by the wing of the WRC rally car. The car’s ride height also appears to have been dropped.

Joining the special GR Yaris at Toyota’s booth is the GR Corolla x GROW Design. It too has received many exterior upgrades to make it much more compelling, including a subtle front splitter and side skirt extensions. It has also been fitted with a set of mismatched wheels with a black finish on the passenger side and a gold/bronze finish on the driver’s side.

Curiously, Toyota hasn’t released any photos of the car’s rear end but we can see that it is sporting a large wing and a new spoiler just below the rear window. The car’s rear diffuser also looks to have been tweaked.

It is unclear if the parts showcased by these two concepts will be produced. What Toyota has confirmed is that the updated GR Yaris will be offered with a suite of official performance parts, including a carbon fiber hood, carbon fiber rear wing, a low-inertia dual-mass flywheel, and a set of new shock absorbers developing for track use.
