Enkei RPF1 17x8 5x114.3 45mm Offset 73mm Bore Brilliant Coat Wheel 05-07 STI/06-10 Civic Si

This is an Enkei RPF1 wheel, measuring 17 inches in diameter and 8 inches wide. It features a 5x114.3 bolt pattern, a 45mm offset, and a 73mm bore, finished in Brilliant Coat. This specific wheel is designed to fit the 2005-2007 Subaru STI and the 2006-2010 Honda Civic Si. The RPF1 is well-known for its lightweight construction and strength, making it a popular choice for performance driving.

Enkei uses their MAT (Most Advanced Technology) flow-forming process to create these wheels. This process essentially combines forging and casting techniques, resulting in a wheel that is both strong and significantly lighter than a conventional cast wheel. This reduction in unsprung weight can lead to improved acceleration, braking, and handling characteristics for your vehicle. The 45mm offset and 5x114.3 bolt pattern are specific to the applications it's designed for, ensuring a proper fit without excessive modification.

When installing these wheels, remember that proper tire mounting and balancing are crucial for optimal performance and ride comfort. It's also a good idea to check your vehicle's brake caliper clearance, especially if you have upgraded your braking system, though the 73mm bore is designed to accommodate many factory and aftermarket setups for the intended vehicles.
