600BHP AUDI S2 (Turbo Noises)

My first time at the ring, so here are the whole trip highlights. It was good practice for what upgrades the car needs for 2025. I went for the vibes not to set records. Germany is the place to live, IMMENSE place.
Upgrades needed are below..
Ar1 tyres all round
RARB
Stiffer rear springs
Geo setup
