No problem whatsoever so far, everything in the car was silky smooth after the change. Car can accelerate much faster than before, can really feel it both during slower and faster speed. When I go uphill climb in the parking lot, I could definitely feel the car engine not working as hard as before. Definitely a highly recommended upgrade for all. As soon as there's an available lightweight pulley for the USDM 5th gen legacy, go get it. The only regret I had was I didn't upgrade this much earlier.
