61612 High Banked Curve 1/45 4-Piece add on Expansion Accessory Set Compatible with 1:43 Scale GO Electric and Battery Slot car Tracks

Excellent

Another nice part to add to your track collection. The cars seem to handle better on the banked track than the flat track. The only downside is that the shorter track parts are harder to get apart, and the track pieces are fragile. Other than that, these are great for expanding your Go track setup to alternate layouts.

cars go wide open all way around track lane changer on each side of track works great

Keeps the cars on the track a little better than standard curves.
