This post covers everything you need to know before choosing your setup, including fitment specs, finish options, performance technology, and why RTR remains the trusted name in Mustang performance and styling.
Why Choose 20-inch Aero 5 wheels for Your Mustang?
The 20-inch wheel size has become the benchmark for Mustang enthusiasts who want the perfect balance between performance and visual impact. It fills the wheel wells on the latest three generations of Mustang - S197, S550, and S650 - as well as the Mach-E, while keeping the ride comfortable.
Available fitments include 20x9.5 +33 and 20x10.5 +45 for Mustang and 20x8.5 +30 for Mustang Mach-E.
These options allow staggered (9.5” up front and 10.5” in the rear) on Mustang or square (same front and rear sizing) setup on Mach-E.
RTR Aero 5 Wheel Fitment Guide
2005-2025 Mustang (S197, S550, & S650 Generation)
The RTR Aero 5 wheels are designed with the perfect offset and fitment for all 2005-2025 Mustangs. From EcoBoost-powered vehicles to Dark Horse, the Aero 5 offers owners an ideal flush fitment.
Similar to the Mustang RTR Spec packages, we recommend running a 275/35R20 tire on the front wheels & a 295/35R20 tire in the rear. RTR vehicles utilize the Nitto NT555 G2 for maximum all-around use, whether you’re daily driving or tracking your Mustang.
2021+ Mustang Mach-E
For Mustang Mach-E, the RTR Aero 5 Mach-E Wheel comes in a standard size of 20x8.5 with a +31 offset and offers the perfect blend of performance and design. The RTR Aero 5 wheel enhances the bold body lines of the Mach-E while maintaining ride comfort and EV efficiency.
On the Mustang Mach-E, the RTR Aero 5 wheel pairs up nicely with the Nitto NT555 G2 in a 245/45/R20 on all four corners.
Flow-Form Technology - Why Aero 5 Performs Ahead of Cast Wheels
Flow-form technology involves spinning and compressing the wheel barrel under heat and pressure. This process creates a denser, stronger structure compared to traditional cast wheels. While cast wheels do the job, the RTR Aero 5’s flow-formed technology results in reduced weight, higher tensile strength, and improved shock resistance.
What other benefits will you see from a lighter wheel? Due to the decrease in overall rotating mass, you may notice a pickup in acceleration, sharper handling over traditional factory-installed cast wheels. The Aero 5 has been tested on RTR’s own Spec 5-D exhibition cars, ensuring real-world validation under some of the most extreme conditions.
Aero 5 wheels are lighter yet fully street-rated for strength and reliability, offering an ideal middle ground between cast and forged wheels.
Design and Finish Options - Make Your Mustang Stand Out
The RTR Aero 5 Mustang wheel features a split-Y spoke design that enhances airflow to the brakes and reduces weight while emphasizing an aggressive, performance-driven appearance.
All RTR wheels are powercoated for a highly durable finish that is ready to take on even the most demanding track days.
Available Finishes:
- Liquid Charcoal: deep metallic tone that suits most paint colors.
- Liquid Bronze: bold, premium finish that pops in sunlight.
- Satin Black: stealthy performance look
When selecting your finish, consider your Mustang’s paint and brake caliper colors to tie the vehicle together with a complementary wheel finish.
