ITV,
According to the Motor Trend article on the ACR ring record the seat was a Racetech seat as noted below excerpted from the article
"A note on the two
Viper ACRs: Except for a Racetech seat with a six-point harness, each ACR is factory stock and fitted with the ********* package, a no-cost option that cuts 40 pounds off the curb weight. About 10 percent of ACR customers order the HCP, which deletes the audio system, trunk carpet, rear cabin sound insulation, tire inflator kit, hood insulator, and steel battery cover.)"
Just for the record it is the Nurburg Ring not Nurnburg which is another city famous for an entirely different and not very good reason.
