Pit Stop in Crash Team Racing Nitro Fueled is nothing more than a bonus shop where Wumpa coins are the currency. You can buy go-kart skins, new characters, wheels, character skins and stickers here. Every day the offer changes in the Pit Stop so you can find something for yourself on a different day, if you are not interested in the current content or offer.
You will get a currency in CTR with each finished race. Their number depends on the route and position at the finish line.
