Those are actually either QC marking or tamper-proof markings. Nothing to worry. All new cars should have this.

Dear Inspira bros...I had been a silent reader all this while till now. I really need to know more about our HU..does it comes with pre-out for external amplifier?
Yeah, in case you wonder, I am also an owner of 1.8MT Black for the past 3 weeks and am loving it every moment.
Already clocked 3k+ km and also touched 188 km/h which was easily achievable.

My only dislike is the soft setting of the suspension...Car looks garang but handles like "siew chey"
Already done spring damper (thank you for the solution in earlier post or should I call it poison?) and now handles superbly. Next in line is the strut bar.
