AKA 1/8th medium inserts

AKA have updated their medium insert with the addition of fluting on the inside, just like the world championship winning soft “Red” insert. This makes the medium insert slightly softer than the original, yet still yields the same characteristics needed in a firmer foam. Fitment for all 1:8 buggy tires and standard AKA short course tires.
