If you are looking for a track with banked turns Google NASCAR Adventure Force Crash Racers. Looks like a modern Sizzler setup. $30 at WalMart.
It is a 2 wide track with grooves throughout including the banked turns. I think it could really help with the open tracks at home.
I haven't put it together and tested it yet but I did put the banks up to see what it was like.
Let me know what you think. https://www.walmart.com/ip/NASCAR-Adventure-Force-Crash-Racers-Figure-8-Circuit/179627565
