Modular Ecosystems: Why Rim Swapping & Upgrades Are Trending in 2025

There was a time when sim racers chose a wheelbase and stuck with the rim it came with—locked into the default feel, function, and look. Fast forward to 2025, and we’re in a whole new era. The buzzword? Modularity.

Swapping out rims has gone from being a niche hobby to a mainstream expectation among serious sim racers. And honestly? It makes perfect sense. Whether you’re drifting through tight corners in a JDM beast, gripping a rally wheel through the snow, or chasing milliseconds in a Formula cockpit—your wheel needs to feel like your car.

Why Modular Wheelbases Are Winning

The demand for quick release systems, customizable rims, and component upgrades is at an all-time high. Why? Because one wheel doesn’t fit all anymore. Racers are craving more:

• Personalization: Swap from a GT-style rim to a round rally-style wheel in seconds.
• Precision: Different disciplines require different feedback response and ergonomics.
• Longevity: A modular system means you upgrade only what you need—saving cost and staying future-proof.

Sim Racers Don’t Want Just Power—They Want Flexibility

Sure, 15Nm of torque is fantastic. But without the right rim in your hands, all that force feedback can feel disconnected. The physical interaction between the driver and the sim starts with the rim.

You’ll often find posts on sim racing forums like, “Which rim are you using with your DD base for drifting?” or “Best GT-style rims under $300?” That’s because racers now understand that rim size, material, and feel directly affect immersion and control.

The Rise of Universal Compatibility

Another trend is moving toward wheelbases that accept almost any rim size or type using standard hubs and adapters. From 270mm round wheels to 320mm deep-dish rims—racers are choosing what fits their style.

And this is where things get exciting for 2025. Brands are waking up to this demand.

With a quick-release hub and compatibility across a variety of rim sizes and styles, it lets you make your setup truly yours.

Whether you’re building your first rig or refining your fifth, the modular wave in sim racing isn’t slowing down—and your wheel should evolve with you.
