Mirco is running an aluminum 1.5mm chassis in his X4’26 car, combined with long M arms, upper links, and optional -1mm clamps.
He mounted a full stiff topdeck setting, but removed the front brace for improved drivability in the center chicane.
The key to a sharp handling is PSS inserts in the front shocks, and with linear springs in both front and rear.
Worth noting is that Mirco raised his rear upper arms on the inside point to lower the rear roll center, and to reduce camber gain, which helped cornering speeds on this tight track.
The car is setup to be rear heavy (49/51 % weight bias) to improve rotation.
Finally, an Avalon Vortex body was mounted in the neutral position for maximum downforce
