Willspeed B7 Fast Fox Conversion Kit

Willspeed B7 Fast Fox Conversion Kit

Looking for something a little different to add to your RC stable? Well, I think Willspeed not only has what you’re looking for, it’s also the winner of the most unique Conversion kit on the market.

The WS Fast Fox is a wild bag of parts that will convert your Team Associated B7 into a this – a low CG buggy that features a carbon lower deck with aluminum chassis rails and a cantilever suspension system that is supposedly offers next-level performance. I only say supposedly because I’ve never tried a setup like this before, but I do see how much lower profile the car is.

You will need a B7 donor and it does retain the mid-motor setup.
