Vibrate during idle (this have to keep your expectation in check, it's the no.1 complaint for 3cyl geely engine. The complaint is so bad even China dont want this engine anymore and switched back to 4cyl, Malaysia already too late to switch back since they now assemble the engine locally.

Vibration during braking, you'll need new disc (or lathe skim the old one) and pad. Bleed all your brake lines too during this brake job.
