Some footage from one of RCN rounds from this year. 

Car specs:
- ~180 HP
- ~1090 kg
- BC Racing coilover suspension
- Hankook slick tires
- Ecumaster EMU Black + ADU 
- based on Polish "Super S Cup 2022" specification

Without any traffic, especially right before start/finish line, it should be sub 8:30 (full Nordschleife). With better suspension it should be also 5-10 secs faster than now.
