Because the B10 has a unique offset geometry found on all new 2025+ models. This factory design change means no off-the-shelf wheel uses all the available and highly valuable clearance. Partnering with Apex Wheels to build these from scratch was the only way to gain the full contact patch this car needs to unlock its full handling and fitment potential.

More tire on the road means more grip. Paired with iE's sway bars and springs, it's a core part of transforming the B10 from soft and understeer-y into a genuinely sharp-handling and fun car.

When installed with a 265/35R20 tire size, the iE/Apex VS-5RS wheel is designed specifically for the Audi B10 S5 as a direct bolt-on fitment for a dramatically improved contact patch and no rub (even with iE lowering springs). For aggressive track setups, a 275/35R20 tire can also be fitted with adjustable upper control arms with additional camber applied to the car. 

Monoblock construction is chosen for the ultimate in both lightweight and strength. Starting from a single solid piece of forged aluminum allows machining extra-deep, side-milled spokes, Sprint™ spec inner lip, deeper concavity, and massive break clearance barrel that still delivers the strength and precision needed to safely use every millimeter of clearance. It's not the cheap option; it's the right one. 

None mechanically, both Anthracite and Race Silver are the same wheel with different color faces. Anthracite runs darker and stealthier; Race Silver is brighter and more classic. Pick the look that fits your build.

Yes. These are 20-inch wheels just like your stock ones, but the similarities end here. Designed with innovative high-clearance barrel design and B10 S5-specific spoke profiles for future brake rotor and caliper upgrades.
