With a precise 73mm bore specification, you'll experience exceptional centering accuracy that's vital for high-performance applications.
The hub machining tolerances maintain strict quality control standards, ensuring perfect alignment with your WRX or STI's hub assembly.
This precision fitment reduces the likelihood of vibration at high speeds and promotes even wear on your vehicle's bearings. For track day enthusiasts and daily drivers alike, the RPF1's hub-centric engineering translates to consistent, reliable performance and enhanced safety.
Frequently Asked Questions
Can These Wheels Be Powder Coated a Different Color Later?
Yes, you can powder coat these wheels later. While it'll affect color durability and resale value, the cost comparison shows powder coating ($400-600) is cheaper than buying new wheels in your desired color.
What Is the Maximum Recommended Tire Width for This Wheel Size?
Like Formula 1 precision, your 17×8 wheel with +45mm offset can safely accommodate 225-245mm tire widths. You'll get ideal tire load distribution and handling characteristics within this range for daily driving.
Will These Wheels Clear Brembo Brake Calipers?
You'll likely have brake clearance with most Brembo calipers as this wheel's 17-inch diameter and +45mm offset typically provides adequate caliper compatibility. However, verify your specific Brembo model's fitment requirements for certainty.
How Much Does Each Wheel Weigh Individually?
You'll be absolutely blown away – while the exact weight isn't listed in the specs, Enkei RPF1s in 17×8 typically weigh around 15 pounds each, offering incredible weight distribution and material durability for performance applications.
Are Wheel Spacers Required for Fitment on Non-Subaru Vehicles?
You'll need to verify wheel clearance and bolt pattern compatibility for non-Subaru fitment. This wheel's 5×100 pattern and +45mm offset is specific to Subaru models, so spacers may be necessary for other vehicles.
