Are lightweight underdrive pulleys worth it??
Was reading in one of the Jap Performance mags about lightweight underdrive pulleys(Crank,Alternator and Power Steering??),and have seen them advertised for the Impreza,but just wondered if they were worth getting,and if so,what improvements would i see(if any!!).
