Remember the 8.25 BTG was done with A LOT of traffic !
nixnuz, the dakar gelb coupé has AC-Schnitzer suspension (and roof spoiler) and also Porsche brakes. It has normal tires, no semislicks. The driver drove the Nürburgring first time in 1993

Smooth lines...
The video car was E46 M3 with Bilstein PSS9 suspension and Michelin Pilot Cup tires. The driver has done ~8.00 BTG with that and he has driven only ~60 laps. Quite good...
