W1 MARKS ITS TURF

LIKE ‘regular’ GTS-R, the W1 gets unique 12mm-wider polypropolene front guards to add even more visual menace to the Gen-f2 HSV’S chiselled look, as well as clearance for the W1’s 265/35R20 front tyres.

GTS-R models also get bespoke front and rear bumpers, with a sharper exhaust-outlet treatment, though only W1’s guard vents and rear spoiler are garnished with genuine carbonfibre. W1 also gets a unique carbonfibre airbox, just 2.5mm thick in some places to clear the radiator (which had to be rotated by six degrees to make everythingt fit). A larger intercooler increases core volume by 49 percent. Other W1 signifiers include extra badging, matte-black side-skirt inserts, matte-black forged 20s and road-legal race rubber.
