1996-2002 SLP Chevrolet Camaro Z28 SS: The Evolution of a Dealer-Built Performance Icon

Chevrolet, SLP

The SLP Chevrolet Camaro Z28 SS occupies a unique place in Camaro history — not as a standalone factory model from General Motors, but as a dealer-approved performance conversion created during the final years of the fourth-generation Camaro (1993–2002). Engineered by SLP Engineering (Street Legal Performance) with the cooperation of Chevrolet, the Z28 SS revived the Super Sport (SS) name for Camaro after a long absence and brought enhanced performance, handling, and distinctive styling to Chevy’s pony car. This article traces the evolution of the SLP Camaro Z28 SS, its production timeframe, package details, and its enduring legacy among enthusiasts.

Origins: Camaro and SLP Background

The fourth generation of the Chevrolet Camaro debuted in 1993, featuring modern styling and performance upgrades from previous generations. Among the trims, the Z28 became the V8-powered performance base, first with the LT1 5.7-liter V8 and later with the upgraded aluminum LS1 V8 from 1998 onward. This engine made the Z28 a legitimate performance car with output in the 300+ horsepower range.

SLP Engineering (Street Legal Performance) was established in 1987 and gained early notoriety for developing emission-legal performance parts and dealer conversions for GM cars. SLP’s most famous early work included the Pontiac Firebird Firehawk series. Building on that success, in the mid-1990s SLP collaborated with General Motors to bring a true Camaro SS back to the market — something Chevy hadn’t offered since 1972.

1996: The Birth of the Z28 SS

The 1996 model year marked the official introduction of the Camaro SS (often referred to as the Z28 SS) thanks to Chevrolet’s approval of an SLP-based performance package. This was the first time the SS badge appeared on a Camaro in 24 years, and it was delivered through a cooperative process: dealers ordered a standard Z28, which was then sent to SLP for upgrades before being delivered to customers.

A total of 2,263 Z28 SS cars were produced for 1996, making them quite rare, and only 264 of those were convertibles — further enhancing collectible appeal.

SLP’s Alteration Package included several performance and visual upgrades:

  • Composite hood with functional air scoop and enhanced forced-air intake.
  • Performance exhaust for improved airflow and slight horsepower gains.
  • Revised suspension tuning for sharper handling.
  • Limited-slip differentials, such as a Torsen unit available as an option for improved traction.
  • SS badging, special floor mats, and unique aesthetic cues.

These enhancements brought the LT1 engine output to approximately 300–305 horsepower, making it the most powerful Camaro offered at the time.

SLP also offered a range of optional upgrades, such as Hurst short-throw shifters, Bilstein sport suspension packages, and performance-focused lubricants, further enhancing the driving experience.

1997–2002: Continued Evolution and Market Changes

In 1997, production continued with SLP’s SS package, and the Camaro also celebrated its 30th Anniversary edition. Certain SS models featured special 30th Anniversary styling and are among the most collectible of these variants today. One example that survives is a 1997 Anniversary SS convertible — reportedly one of only about 50 Black-finish 6-speed SS convertibles produced with the SLP package.

By 1998, General Motors streamlined the SS ordering process. The SS content could now be ordered through the Chevrolet Dealer Communication System (via RPO code WU8), which meant fewer steps involving SLP installations, though SLP continued offering supplemental performance parts.

Throughout the late 1990s and early 2000s, many Z28s equipped with the SS package retained the LS1 V8 — producing roughly 305 horsepower, sometimes rated up to 310 hp with optional performance exhausts.

SLP-equipped SS cars often featured other upgrades beyond power, such as unique 17-inch ZR-1 style wheels, dual-exit exhausts, SS badging, and handling tweaks that differentiated them from standard Z28s of the period.

Vehicles like the 2000 Camaro Z28 SS SLP retained many period features such as six-speed manual transmissions, Auburn limited-slip differentials, performance exhausts, and SS-specific interior trim.

While SLP remained involved with performance parts and installations through the late generation, by 2002 Chevrolet itself was increasingly integrating SS production more directly at the factory level — diminishing the explicit SLP involvement compared to earlier years. However, SLP still lent parts and customization packages, and some SS cars of that year still retain identifiable SLP equipment like performance intake and dual/exhaust systems.

Models and Packages Offered

Because the SLP Camaro Z28 SS was not a factory trim but a performance conversion package, it did not have traditional trim levels like the factory LS or special edition trims found in newer Camaros. Instead, enthusiasts recognize several informal groupings based on production features and options:

1996 Z28 SS (SLP Alteration Package)

  • First SS offering via SLP with cobalt enhancements.
  • Functional hood scoop and forced air induction.
  • Performance and appearance improvements by SLP.
  • Optional suspension and traction upgrades.

1997 Anniversary SS (SLP + 30th Anniversary Edition)

  • Commemorative styling elements alongside standard SS enhancements.
  • Limited production and high collector interest.

1998–2000 SS with Continued SLP Influence

  • SS packages ordered through GM with SLP components contributing to performance enhancements.
  • Manual transmissions and performance exhausts common.

2001–2002 SS with SLP Parts

  • Later SS cars sometimes include SLP performance intake, exhaust, and differential upgrades, though GM increasingly assumed SS production integration.

Even though SS cars were powered by the same LS1 V8 found in other Z28s, features like the SS composite hood, unique rear spoiler, ZR-1 wheels, and suspension upgrades distinguished them from base Z28 models.

Performance and Driving Character

The SLP Z28 SS — especially in its early iterations — was designed to be a high-performance street car that bridged the gap between stock Z28 models and more race-oriented builds. The SS was capable of brisk acceleration and improved handling, helped by the lower-restriction exhaust, enhanced intake, and upgraded suspension options.

Performance figures from the 1996 SS indicated a 0–60 mph time in the low to mid-5 second range, with top speeds upwards of 150 mph, competitive with contemporaries like the Ford Mustang Cobra of the same era.

While horsepower gains on many SS cars were not dramatic compared with the standard Z28 — often in the 300–310 hp range — the real value of the package was in aesthetic distinction, improved handling components, and factory-backed quality.

Historical and Collector Significance

The SLP Camaro Z28 SS holds a special appeal to collectors for several reasons:

  • Resurrection of the SS name: After more than two decades without the SS badge on Camaro, the SLP-endorsed SS in 1996 marked a return of a true Super Sport designation.
  • Cooperative performance history: The collaboration between SLP and Chevrolet in the mid-1990s reflects an era when dealer/third-party performance specialists could work closely with OEMs to bring enhanced performance cars to market.
  • Limited production: With only a few thousand of the earliest SLP SS cars made, many of which were convertibles or special editions, these cars are far rarer than standard Z28s.
  • Evolution of the SS badge: Early SLP Camaros represent a bridge between classic performance heritage and modern factory SS models that Chevrolet would later integrate more fully in the Camaro lineup.

Future Outlook

Since the end of the fourth-generation Camaro and the retirement of SLP’s direct dealer conversion programs, the SLP Camaro Z28 SS is now purely a collector and enthusiast vehicle. No modern equivalents carry the same dealer-built SS designation.

However, the Camaro SS name has endured into newer Chevrolet generations (2010 onward), with factory-engineered SS trims that carry significant performance upgrades directly from GM rather than via a third-party conversion.

Collectors and enthusiasts continue to prize original SLP SS Camaros because they represent a specific moment in performance history — where a third-party specialist could, with manufacturer blessing, bring a classic performance badge back to a beloved sport coupe. As interest in limited-production and transitional performance models grows, well-documented SLP Z28 SS cars can maintain or grow in value due to rarity and historical significance.

Conclusion

The SLP Chevrolet Camaro Z28 SS is an important piece of Camaro and American muscle car history. Born from a partnership between SLP Engineering and General Motors in the mid-1990s, the SS brought the Super Sport badge back to Camaro after decades, offering enhanced performance, distinctive styling, and a special place in enthusiast hearts. Though produced in limited numbers and never a distinct factory model, the SLP SS remains a celebrated and collectible variant of the iconic Camaro — a reminder of a unique era when performance specialists and manufacturers worked together to redefine what a pony car could be.
