The 2020 Lexus GS F will be getting a minor update. According to the Lexus Global Newsroom, the standard aluminum wheels will now have a matte black finish and the Brembo brake callipers are now offered with a blue finish as an alternative to orange.
Additionally, the Black & Accent White interior has been tweaked to “make the white accent stand out even more”. Most importantly, the suspension has been improved. The rigidity of the steering bushing has been increased to provide a more linear steering feel. In addition, the rear toe control arm bracket is now made of die-cast aluminum to reduce weight and increase rigidity.
The Lexus USA GS F page confirms that the matte black wheels are standard on 2020 GS Fs (hand-polished wheels are a $600 option). The blue Brembo calipers are a no-cost option for 2020, but there is zero mention of the orange calipers, and are likely no longer available in the USA.
