GM06

RTX GM06 wheels: monoblock 5x120 in 18 and 20 inch

The RTX GM06 is a clean monoblock wheel built around a 5x120 bolt pattern, giving you a single-piece design in 18- and 20-inch diameters. The face runs a tidy multi-spoke pattern that suits daily drivers and street builds on that bolt circle, and it slots into the wider RTX lineup as a straightforward, well-priced option.

Sizes and fitments stocked

The GM06 is stocked in a tight, usable range so you can match your ride height and clearance without guesswork:

  • 18x8 +35, 5x120 — the smaller setup, good for stock-height cars that want a fuller sidewall.
  • 20x8.5 +35, 5x120 — the larger, slightly wider fitment for a more filled-out look.

Every size runs a +35 offset on the 5x120 pattern, so it works on common 5x120 platforms. Concrete examples in stock include the 18x8 +35 Gloss Black, the 18x8 +35 Chrome/PVD, the 20x8.5 +35 Gloss Black, and the 20x8.5 +35 Chrome/PVD. If your car runs a different bolt circle, check the RTX 5x114.3 or RTX 5x112 ranges instead.

Finishes

The GM06 comes in two finishes: Gloss Black for a stealthy, low-key look, and a bright Chrome / PVD for a mirror shine. Both are offered across the 18- and 20-inch sizes.

Price and who it suits

The GM06 runs from $247.99 for the 18x8 Gloss Black up to $418.99 for the 20x8.5 Chrome/PVD. That makes it a sensible pick for a 5x120 owner who wants a clean upgrade over stock without stretching the budget. Financing is available through Affirm, Katapult, Klarna, PayPal Credit and Snap Finance at checkout.

How it compares in the RTX range

If the GM06 isn't quite your look, the Spark and Crush offer different spoke treatments, while the Hida and Trek lean toward heavier, more rugged faces. For a bolder mesh, look at the Illusion, and the Force rounds out the street-focused options.
