WS6 Package

WS6 Package
Das WS6 Package wurde mit den Modellen ab 1978 eingeführt....
The WS6 package made its public introduction with the 1978 Trans Am, since TA
and Formula shared the same chassis setup in 79 it became available on the Formula Firebird.

Herb Adams had been working for Pontiac and helped develop the Trans Am, he took
on the task of trying to create a car (actually a few) to compete in the S.C.C.A. Trans
Am road races these were dubbed FireAms and he marketed some of the
improvements through his own company VSE (very special equipment) so that other Pontiac owners
could build a FireAm of their own.
Some of the results of his efforts later found their
way to production cars under the WS6 special performance and handling pkg. most
notably the 15x8 rims and the rear disc brakes.
WS6 improved the handing measurably over the std TA . On build sheets and in
service manual the WS6 is referred to as “TRANS AM MARK IV”.
