The Agency Power pulley is the same diameter as the stock pulley. Keeping the diameter the same allows no issues to occur with the alternator as under driven pulleys do sometimes. Weighing only 1.0lbs, it is almost 4lbs lighter then stock, it is the lightest pulley on the market. This gives you quicker throttle response as well as more horsepower and torque sooner. Saving on rotating mass results in better performance.
The AP pulley is a great performance part for your Scion FR-S and Subaru BRZ.
