I don't really get it. the gains you get from removing the AC compressor are going to be so minimal. Just turn the AC off when you are about to race. What you want to try to shave another 10lbs? I think you may be on the wrong platform. These cars are not light.
    to be fair.. the compressor alone weighs a LOT more than 10lb.. plus condensor, lines etc.

    If i were to de-register mine and track-only it.. it's pretty obvious weight redution choice if i were still overweight

    i'd probably look into getting a plate made up with a wheel sitting on it to replace the compressor though, and be able to keep the right sized belt (well, i'd look into it lol)

    Unless going for a really hardcore track-car removing the AC-pump and other AC components is really not worth the hassle.
    If you need to ask on a forum how to do this, you better not do it at all.
    Removing the AC pump also halves the reach of the deflection pulley making the tolerance of the belt even more critical.

    The idea of removing the power steering pump from the equation makes me wonder if you have ever driven a non-powersteering car at all?
    Glad you steered clear of that idea. That would have ruined your drive big time.
    In fairness non power steered cars that are designed as such do steer lighter than a power steering car without a pump, but if you have the choice between non power steering and BMW power steering it really is a no-brainer.
    There are two theories to arguing with women. Neither one works

    cars with broken power steering aren't TOO bad at speed (having had acc belts snap before), but not something i'd want to add to the stress/strain of track driving, especially when not a car designed unassisted (which is difficult enough already!!)

    Wouldn't the steering rack start failing eventually if you drive without power steering?

    Driving it hard would suck, and driving it at low speeds would be beyond miserable. Good to see OP shelved this idea.
