How about using some other device to generate the wheel speed data. Maybe you could put a little drive wheel of some type against one on the tires to get a much higher angular rate. I remember those little bicycle sirens that made contact with a tire, and spun very rapidly. A Hall cell crankshaft pickup from a wrecked car would easily generate a wheelrate signal. an alternative would be to simply use a much smaller wheel in contact with the ground, coupled with some sort of Hall cell generator. I'm thinking
