DAMPERS

AERO

• Front Splitter: Max attack setting (if adjustable, +2 from base)
• Rear Wing: 5 (of typical 1–10 range) — balanced for Döttinger top speed vs Brünnchen/Karussell stability
• Downforce Level: Medium-high — prioritize Fuchsröhre/Bergwerk stability without killing Döttinger top speed
• Brake Ducts: Front 2 / Rear 1 (single lap, minimal cooling needed)

KEY SETUP NOTE

• The CSL's short wheelbase and aggressive rear diff power lock make it snappy over Brünnchen's compression bumps and the Flugplatz crest — slightly softer rear ARB and increased rear slow bump damping are critical to keep the rear planted without sacrificing the rotation this car is famous for in Adenauer Forst.

TRACK GUIDE

• Hatzenbach: Trust the front end on compliant suspension — carry speed through the direction changes, let the car ride the bumps rather than fighting them.
• Flugplatz: Lift minutely over the crest if rear feels light; the CSL's weight transfer rearward on the crest can unsettle it — stay smooth on the wheel.
• Fuchsröhre: Commit flat-out downhill into the compression — the setup's stiffer front wheel rate helps resist excessive dive, allowing late, hard trail-braking into the right-hander.
• Karussell: Stay on the banked inside line, roll speed through rather than attacking the apex — this preserves momentum onto the following straight far more than any tenths gained from aggressive braking.
• Döttinger Höhe: Maximize exit speed from Tiergarten chicane — this is where top speed and lap time are won; minimize wing drag choice pays off here if sacrificing is viable elsewhere.
