Timo Witt of Audi Tradition was kind enough to give us a rundown on the differences between the Audi 200 Turbo Quattro Trans-AM and the 1989 Audi 90 Quattro IMSA GTO cars which dominated their respective championships, even with 3 rounds missing and last-minute development for the IMSA GT series which Timo touches on along with data logging capabilities in the late ’80s and the challenges of boost control for circuit vs rally racing.
