Kia Stinger GT on BC Forged RZ05 20" Dark Brushed Black Wheels
A matte-red Kia Stinger GT rolled into the bay for a lightweight forged-wheel upgrade — and left on a custom set of 20" BC Forged RZ05 monoblock wheels in Dark Brushed Black. Front 20x8.5, rear 20x10: a staggered fitment that fills the arches, shows off the red calipers, and cuts unsprung weight versus a typical cast alloy.
Why forged monoblock for the Stinger GT
BC Forged builds these RZ05 wheels as one-piece (monoblock) 6061-T6 forged aluminum. In plain language, that means the blank is forged under high pressure, then CNC-machined into the final spoke design — stronger and usually lighter than a comparable cast wheel of the same size. For a performance sedan like the Stinger GT, lower unsprung weight helps the suspension react faster, which owners feel as sharper acceleration response and shorter, more confident braking when the rest of the chassis is sorted.
- Faster acceleration feel from reduced rotating mass
- Shorter braking distance potential with less unsprung weight to manage
- Up to 40% lower unsprung weight than typical cast alloy wheels (application-dependent)
- About 30% stronger and more rigid than conventional aluminum cast wheels
The set arrives as a custom forged package — sizes, finish, and offsets dialed for the Stinger before the car ever hits the lift. CarGym is an authorized dealer of BC Forged, so you are shopping real BC Forged monoblock hardware with custom fitment support, not a generic replica listing.

Install and reveal
On the lift, the OE wheels come off and the RZ05 set goes on with Continental performance tires. Through the spokes you can see the red calipers and drilled rotors — the Dark Brushed Black face keeps the package aggressive without fighting the matte red bodywork or the carbon aero already on the car.
Street-side, the staggered 20" setup tightens the stance. Front three-quarter shots show how the 8.5" fronts tuck under the fenders with the carbon lip and grille inserts; the side profile makes the 10" rears and carbon side skirts read as one continuous line.
Detail frames from the bay pick up the carbon rear diffuser, LED headlight and grille insert, and how deep the RZ05 spokes sit relative to the tire shoulder — the kind of fitment story that matters as much as the spec sheet.
Care notes
Dark brushed finishes look sharp and hide light road film better than bright machined faces, but they still prefer pH-neutral wheel cleaner, soft brushes, and drying after wet washes — especially around the lip and spoke pockets. Torque the lugs to Kia spec after the first short drive, and re-check after a few hundred kilometers.
