For some strange reason, GM
dropped the Z28 for 1988, however the IROC-Z continued on strong as the
performance leader. All Camaro's were now built with the rear spoiler with its imbedded
third brake light. The Base Camaro 5.0s were now offered with the TPI system,
rated at 170hp.
The rarest and most impressive Camaro beginning in 1988 was the IROC with the
1LE package. Available on IROCs with the 5.0 and 5.7 TPI engines, the 1LE
package was built specifically for road racing and featured huge disc brakes, a
balanced aluminum driveshaft and major suspension tuning with stiffer sway bars,
lower, stronger springs and shocks. This 1LE was somewhat bare-bones in terms of
options, but it was built specifically for road racing, so who cares ;).
