The “ACR” and “GT2” Connection
These specific dimensions were standard on two of the most collectible Vipers in history:
-
Viper GTS ACR (American Club Racer): Introduced in 1999, the ACR used these lightweight forged BBS wheels to reduce unsprung weight and improve track handling.
-
Viper GTS-R / GT2 Commemorative Edition: To celebrate Dodge’s 1997 FIA GT2 championship win, 100 white-and-blue “GT2” Vipers were built in 1998, all featuring these BBS wheels as a signature visual element.

Why They Are So Desirable
-
Extreme Weight Savings: These one-piece forged aluminum wheels are significantly lighter than the standard cast-aluminum “5-spoke” or “swirl” wheels. Reduced unsprung mass allows the suspension to react faster and sharpens steering turn-in.
-
6-Lug Rarity: Most sports cars use 5-lug patterns. Because the Viper uses a 6-lug truck-style bolt pattern, you cannot easily find high-end wheels from other brands (like Porsche or BMW) that fit. These BBS units were bespoke to the Viper.
-
Modern Market Value (2026): As of early 2026, the market for these wheels has hit an all-time high.
-
Used Sets: Typically fetch $4,000 to $5,500 depending on curb rash and finish.
-
New Old Stock (NOS): Collectors have seen “New in Box” sets listed for as high as $9,000.
-
-
Brake Clearance: They were designed specifically to clear the larger calipers used on the ACR, providing better cooling for heavy track use.
