How to Unlock: Get at least one star on every regular Grand Prix (150cc) and Mirror Mode race to unlock the Gold Standard kart. Like Mario Kart 7, there is an unlockable Gold Kart, Gold Wheels and Gold Glider in Mario Kart 8 - but the gold items are very difficult to unlock. The interval changes to 100 coins per unlock after you pass 1000 coins. Vehicle customization parts unlock randomly at 50 coin intervals - similar to Mario Kart 7. If you play with more than one person, their coins will also contribute to your game's overall coin count and you will unlock items faster. In any mode, collect Coins found scattered about the Tracks to unlock more karts, bikes, wheels and gliders. Unlockable Vehicles and Parts in Mario Kart 8 Deluxe
