Just know that not all of these are S3s just the majority of them and considering they're all the same generation i thought might as well call it an S3 compilation lol.
glenmiester when the Front Tires lost traction the Haldex puts up to 100% of the power to the rear, you can do this with a Haldex Controller too, just Front Or rear oder 50/50 40/60. whatever you want, but the Yellow s3 made the Donut with all 4 Wheels (Sry for my Bad english, im from Germany)
S3 haldex has a base config on 97/3 on basic run, can adjust to 50/50 when pushin on, or loss front transmission. you can also put a Stage 1/2/3 haldex module that allows you to do 50/50 sport mode as you wish (each stage gives you more options and more %). this one probably got a stage 2 or 3 haldex module (with a swith in the car)
S3 hat ne Haldex, wenn man da den Stecker abzieht oder die Sicherung entfernt schließt die Kupplung nicht und er ist nurnoch ein Fronttriebler, das sollten alles S3s sein, da sie hinten breiter sind als n normaler 8l
