IROC-Z Camaro History
The IROC-Z Start
For those years that the IROC-Z was in production, they became such a staple in the Camaro lineup, Chevrolet would drop the Z-28 from production for the years of '88, '89, and '90. The IROC-Z would become your primary choice if you wanted a performance-based Camaro.
The IROC-Z: A Better Camaro
What mostly stood out about the IROC-Z is its 5.7-liter (350-cu.-in.) Tune-Port Injection (TPI) engine which was bigger than its sister motor, the 5.0. The 350 TPI came with a four-speed 700R4 automatic transmission and a special suspension package better known as the 1LE package that included:
- 4 wheel disk brakes
- 3.42 positraction rear-end
- An aluminum driveshaft
- Large 12" front rotors
- Aluminum calipers
- Engine oil cooler
- Gas tank baffles
- Larger anti-roll bars
- Specially valved Delco-Bilstein shocks
- Larger diameter sway bars
- Steering/frame brace known as the "wonder bar" and
- More aggressive springs that lowed the Camaro by .05 inches.
The special Camaro would also get 16-inch rims, an upgrade from the smaller 15-inch rims, more aggressive side-skirts for the body kit, large IROC-Z decals on the doors, and special trim.
Although throughout the years the IROC-Z was released from the factory with a few different trim options and setups like t-tops, controvertible, and even a 5-speed transmission, the most common trim options are mentioned above.
Unfortunately for the IROC-Z, it was produced in a time when power was not a priority, and the horsepower and torque numbers it boasted in the mid-to-late '80s sucked in comparison to today's sports cars. But the reason why the IROC-Z is a collector car and will stay a collector car is not because of its power outputs, but because of its connection to the IROC Racing Series and its road course capabilities.
Shopping for an IROC-Z Camaro
If you're searching for an IROC-Z, you must be careful for there are a lot of impostors out there. A lot of the exterior IROC-Z options such as the vented hood, front spoiler, and ground effects options were available for order on regular Camaros, Z28s, and can be bought as aftermarket pieces. So check the VIN numbers and do some research via. some reputable sources before you go laying down big money.If you already own one, I would suggest saving it and passing it on to someone in your family, because in time they will be just as valuable as a Camaro from the Muscle Car era.
