For large, flowing tracks, you’ll find the C12 Mark-2 bodyshell very hard to beat! The closed-cockpit design and low, chassis-hugging details are ideal for bigger tracks with lots of speed sections. Try it and you will love it!
For small, tight tracks, try the #61730 C12 Mark-1 bodyshell, which is an open cockpit design, perfect for extra traction in the twisty bits! As a compromise between the two designs, try the #61732 C12 Mark-3 closed-cockpit, high downforce version.
