Automotive Engineer and Toyota veteran David Chao takes his 2020 GR Supra to the next level by upgrading both the tires and wheels - resulting in a substantial road performance improvement. Comparing to the 2021 Porsche 911 that David is driving this week, he concludes that the upgraded GR Supra comes very close to the capability of the 911 in terms of cornering, handling, and road feel.

David walks through the entire process and the full details of what were changed from the 19" OEM wheels and tires to the upgraded 20" Michelin Pilot Sport 4S tires and Variant wheels. He also talks about the Pirelli P-Zero All Season Plus winter set that he uses during the winter months on the GR Supra.

Many thanks to Michelin Tires Canada, Variant Wheels, and 1010 Tires for the collaboration.
