they should be lighter than factory pulley's. your acceleration should be a bit quicker than factory....unorthodox pulley's are known in the japanese scene....i guess they shouldnt be bad on a bmw... very reputable company....make sure you dont have the crank pulley though....i hear it can fuk up your car real bad....

To clarify, the crank underdrive pulley can only cause problems if used in conjunction with a lightened flywheel. If you're using the stock dual-mass flywheel a crank pulley is fine.

That said, the Unorthodox pulley set is a nice pulley set, they are lighter and stock, which is good for engine response, and free up some horses.
