The TSM is very nice for bashing (which it what I use this for), it seems like basically a gyro sensitized to the rear end and smoothes things out nicely on wet grass etc. I don't know if I would want to race with it, it may limit your "slide job" capabilities. I run this thing in a really large open park in my area and the TSM really keeps that rear end planted on wide sweeping turns under power. Definitely a nice feature they came out with.
