Zitat:The 1984 and 1985 wheels were made from an aluminum casting that do not shine much when polished.

Enkei produced the 1986 and 1987 wheels for GM and they were made of an aluminum that could be polished to a high luster. These Enkei produced wheels also were slightly larger on the inside, which means you can use the '88 and later 2-piston front brake caliper with a 13" rotor. The Enkei produced wheel can be identified by a small symbol in one of the slotted radial wheel vents which looks like an "m" grafted to an upside down "J".
