I have been getting great performance and longevity from answer shoes and bells on my losi vehicles. Been packing some horsepower in the engine compartment and still getting 3 gallons outta shoes and bells. Mike gave me the V2 shoes to try and i just ran them on a really stout engine this past weekend. The a&n letters were still legible and no slag were on the shoes. They performed excellent. What a great clutch setup. Been running 2 gold, 2 silver springs and couldn't be happier. Damn good product. Thanks for hooking me up Mike.
