Subaru Wheels

A Comprehensive Guide in Upgrading Wheels

Swapping out your factory wheels can drastically change how your car looks and handles. For WRX STI owners, increasing rim size requires more than just visual consideration—it can impact ride quality, handling, and even your suspension. Here's what you should know when upgrading your STI's wheels.

Best Practices When Increasing Rim Size for Your WRX STI

Check Clearance and Fitment

Ensure the new wheels won't rub against the fenders, brake calipers, or suspension arms.

Use Compatible Tire Profiles

Select a tire with the proper aspect ratio to maintain overall diameter and accurate speedometer readings.

Balance Style and Weight

Lighter aftermarket rims improve performance, but overly large wheels can add rotational mass.

Inspect Your Suspension Setup

Upgraded wheels can affect ride stiffness, so verify your suspension system can handle the change.

Recalibrate TPMS Sensors

When switching wheels, make sure your tire pressure monitoring system is synced correctly.

Avoid Excessive Offset Changes

Dramatically different offsets may stress wheel bearings or impact steering geometry.

Torque Lug Nuts Properly

Use a torque wrench to secure your new wheels and avoid uneven pressure on the hub.
