Well-known GM tuning company Callaway Cars released its new 35th Anniversary Package for the C8 Corvette Stingray this week, which is now available to order from Callaway-authorized Chevy dealerships in the United States.
The 35th Anniversary Package for the C8 Corvette Stingray was developed by Callaway to commemorate the 35-year anniversary of its “RPO B2K” tuning program for the iconic American sports car, which launched in 1987 and concluded in 1991.
The B2K was the Connecticut-based company’s first major Corvette tuning program and saw it fit the stock V8 engine with two turbochargers and a long list of other upgrade parts, boosting output to over 380 horsepower and 580 pound-feet of torque. Just like modern-day Callaway vehicles, this tuning package was available to order from authorized Chevy dealers through GM’s “Regular Production Order” or “RPO” process. More than 500 examples of the C4 Corvette were fitted with the RPO B2K package before it wound down toward the end of 1991.
Callaway’s new B2K package pays homage to the original, which helped establish Callaway as the well-known and widely respected GM tuner that it is today. Available through authorized Chevy dealers and carrying RPO code PCY, this package includes a full carbon aero kit with a front splitter, rocker extensions, a rear diffuser and a unique “Slot Gap” rear spoiler, along with lightweight nine-spoke forged alloy wheels, Callaway sill panels and floor mats, an interior build plaque, billet pedals, Callaway exterior badging, a Callaway car cover and a Callaway-branded Mothers detailing kit. The package also includes Callaway’s ‘Double D’ exhaust, which is a significant 40 pounds lighter than the factory performance exhaust and is also 50-state emissions compliant.
Callaway offers some optional equipment with the RPO PCY package, including black chrome exhaust tips, chrome/carbon flash painted emblem sets, locking lug nuts and premium wheel finishes. Customers can also choose to have their vehicle delivered to the dealership, the National Corvette Museum, the Callaway Factory in Old Lyme, CT, or at Thompson Speedway in nearby Thompson, CT.
As this is a dealer-ordered tuning program, customers must ensure their order form contains the correct RPO codes to ensure the application is not denied by GM. RPO codes that must be included on the order form include RPO Z51 (Z51 Performance Package), RPO ZF1 (aero delete) and RPO Q8P (Open-5-Spoke Bright Silver-Painted Aluminum wheels). The order will be rejected if it contains any of the RPOs: 5DF, 5V5, 5V7, 5VM, 5W8, 5ZC, 5ZD, 5ZU, 5ZZ, CFY, PDV, Q8Q, Q8S, Q8T, QE5, RIK, RIN, RNX, RWH, RWJ, RXH, RXJ, S6S, SB7, SFE, SJI, SL1, SL8, SPY, SPZ, SQU, STI, VQK, VWD, VYW, WKQ, WKR, WL0 and ZCR.
This tuning program does not raise the output of the factory 6.2L LT2 V8 engine, which is rated at 495 horsepower and 470 pound-feet of torque with the optional factory performance exhaust equipped. The eight-speed dual-clutch transmission also remains untouched.
