Some new cars don’t bother with a rear wiper blade. Then others, like the Polestar 4, don’t bother with a rear window. Now we can add the Porsche 911 GT3 RS to the short list of vehicles averse to visibility.

Manthey Racing has unleashed a new performance package for the Porsche 992 GT3 RS.The $80,300 kit—yes, EIGHTY THOUSAND DOLLARS—transforms the GT3 RS into an even more aerodynamically aggressive machine,

This is the Porsche 911 GT3 RS with a Manthey Kit fitted. For those who know, you know what this is all about. For the uninitiated, the “Manthey Kit” is a bit like ordering off of a secret motorsport-influenced options menu.

Working together, Porsche says that the aerodynamic modifications can produce more than 2200 pounds of downforce at 177 mph, an increase of over 300 pounds compared to the vanilla GT3 RS.

Manthey-Racing has an upgrade package for the 911 GT3 RS, which the company claims significantly improves lap times.
