The 1988 Chevrolet Corvette
The 1988 Chevrolet Corvette represented the 35th anniversary for Corvette. To celebrate,
a 35th anniversay model was made available and 2,050 were sold. This option included
white paint with a black roof bow, white leather interior including the steering
wheel, white painted wheels and special badging inside and out. This option was
only available on coupes. New additions for the 1988 Vette included carpeted door
sills, solution dyed carpet and improved ventilation for coupes. A new muffler system
was standard on coupes with the 3.07:1 rear axle ratio, it provided an extra 5 horsepower
due to its less restrictive flow. The new muffler system was deemed too loud for
the convertible and the 2.59:1 rear axle ratio coupes and was not installed. Standard
brake rotors were thickened and suspension changes were made to improve control
during heavy braking. The Z51 and Z52 options were upgraded to include 17 x 9.5
inch wheels with P275/40ZR-17 tires mounted on them. The Z51 option (only available
on coupes) also included a finned power steering cooler, higher spring rates and
larger front brake rotors and calipers than 1987.
