This is the
first year the 1LE high performance option became widely known. The 1LE
featured 4 wheel disk brakes, a 3.42 posi rear end, an aluminum drive shaft,
large 12" front rotors, aluminum calipers, engine oil cooler, larger
anti-roll bars and gas tank baffles. There were also numerous spring rates
available. The package could only be ordered without air conditioning or
fog lamps. 1990 also marked the year the the TPI systems changed from the
Mass airflow system to the Speed density system. These differences are
explained in the TPI tech section. The Speed density system allowed an
extra 5 horsepower from the 350, upping the ante to 245.
Visually, the
exterior of the 90 IROCs once again did not change, but looking through the
windows will show that they now had a driver side air bag as well as revised
instrument cluster.
