Carrera . Upgrade your racetrack with this lane-change curve. The right-hand curve consists of two 1:24 scale track pieces and is perfect for passing. From the outer lane, you can easily switch to the inner lane here and pass your opponent. They won’t have a chance to pass you again until the next lane-change section. You can use this to upgrade your 1:24-scale digital racetracks. Carrera DIGITAL 124 , and Carrera DIGITAL 132 are the compatible racetracks for this expansion set. This track section adds some excitement and is sure to cause a crash or two. If you're not careful when changing lanes, you'll run right into your opponent or end up trailing behind them. So use this track section wisely to stay in the lead!
