Japanese tuner Skipper has released some mods for the 2013 Lexus GS, starting with a front lip spoiler available in exposed carbon fiber or body-color-matching:
There’s also this carbon fiber front bumper cover:
Rounding out the package are side skirts, a carbon fiber trunk decal, roof spoiler, and exhaust covers:
All told, these mods are retailing for ¥425,500 yen, or $5,150USD in direct conversion, and North American availability is unknown.
(I’m still shocked at how much the lip spoiler changes the look of the GS — is this the first “essential” mod?)
