In 30 years of car ownership I’ve never before broken a wheelstud. In the 6 months I’ve owned the GT86 I’ve broken two. And it’s not through overtorquing - I’m religious about using a torque wrench. They’re just shit. Next one that breaks, the OEM ones are all gone and it’s aftermarket all round.
Strange thing is they’re common to practically everything Subaru’s made in the last decade. You’d have thought they’d have sorted that shit out by now.
