Like the mk4 Supra, Toyota expects the new GR Supra to be popular with the tuners and aftermarket parts manufacturers.. With that in mind, Toyota has designed the all new Supra to be ready for modifications straight out of the factory.
As seen on an article written by Motor Trend, the engineers at Toyota designed the front of the car with air intakes large enough to ensure modified examples get enough air if aftermarket tuning companies wanted to turn up the boost. As the stock car does not need the extra cooling, Toyota then simply blocked off the excess intakes with black plastic which the standard car doesn’t need. All tuners need to do is fit different grille inserts free of this plastic to increase the amount of air the car can suck in.
Also at the front, Toyota built in air ducts near the front wheel arches to push away air which is being sucked in from the front. These air ducts are sealed from the factory but they can be replaced with functional ones.
In the same way, the engineers also created air intakes for the front and rear brakes but they have been sealed off too from the factory as they are not needed too.
Moving to the rear, Toyota made sure there are space for additional cooling equipment for the limited-slip differential when tuning companies start to increase power of the sports car. They even went to the trouble of installing a mounting location for these parts.
Lastly, the GR Supra's rear bootlid has been reinforcements under the composite skin, allowing a large wing to be easily fitted with its forces transferred safely through the bodywork. It even features pre-tapped holes in the strut towers and radiator supports so strut-tower bracing can be easily fitted.
