RS09
RTX RS09: A Clean Monoblock Wheel for Everyday European and Import Builds
The RTX RS09 is a monoblock wheel with a tidy, understated face that suits daily-driven European sedans and imports. It sits within the wider RTX lineup as a straightforward, road-focused design rather than a flashy show piece, and its finish keeps the look simple and easy to live with.
Sizes and Fitments Stocked
The RS09 is stocked in 17, 18, 19 and 20 inch diameters, with widths of 7.5, 8 and 8.5 inches. Offsets run +40 and +42, and both 5x112 and 5x114.3 bolt patterns are available, covering a broad range of Volkswagen, Audi, Honda, Hyundai and similar hubs.
To make the range concrete: the 17x7.5 +40 in 5x114.3 is the entry point, while the 18x8 +40 and 19x8 +40 step up the diameter without going wide. The 20x8.5 +40 is the largest fitment, and for 5x112 hubs there is a 19x8 +42. These offsets are moderate, so the wheel clears most stock brake setups and works well on lightly lowered or factory-height cars.
Finish
The RS09 comes in Gloss Black, a versatile finish that reads sharp on light and dark paint alike. If you want a different tone across the RTX range, browse black RTX wheels, silver, or bronze options.
Price and Who It Suits
The RS09 runs from $198 to $339 depending on size, which puts it in reach for a first upgrade or a clean OE-plus refresh. It suits owners who want a restrained monoblock look without stepping into premium pricing.
If you want more character, the RTX Spark brings a busier spoke pattern, and the Crush leans toward a mesh look. The Force is a bolder split design, the Ink goes darker and more aggressive, and the Trek targets a more rugged, utility-minded stance. Compare a few before you commit.
