DAMPERS

AERO

• Front Splitter: 4 (of typical 1–10 scale, aggressive but balanced)
• Rear Wing: 6
• Downforce Level: High-medium — prioritize front stability for Tamburello/Piratella braking without killing top speed on the two long straights
• Brake Ducts: Front 3 / Rear 2

KEY SETUP NOTE

• The M4 GT3 Evo's front end must be planted through Tamburello and Piratella without going so stiff on the front ARB that you lose rotation at Tosa and Rivazza — this setup leans slightly softer front ARB (6) with a touch more rear wing to let you brake later into the hairpins and still get clean power down, which is where most of Imola's lap time is won.

TRACK GUIDE

• Tamburello (T1): Trail-brake late but straight-line stability is king — the stiffer damper rebound keeps the car settled over the kerbs; don't lift mid-kerb or you'll unsettle rotation for Villeneuve.
• Tosa (T5): This is the most important traction zone on the lap — get the car rotated early on entry (use the diff coast setting to help rotate) so you can lay power down flat from apex for the long run to Piratella.
• Piratella (T8): Committed uphill brake — trust the front aero and brake bias; any hesitation here costs time all the way to Acque Minerali.
• Acque Minerali (T9/10): Stay smooth over the compression — the medium-firm rear damper setup prevents bottoming but you must be precise with throttle modulation through the dip.
• Rivazza 1 & 2 (T16/17) into the final chicane: Sacrifice a cleaner Traguardo chicane line for a perfect Rivazza exit — this is the last and most important traction zone before the pit straight, and where the lap is won or lost.
