Great optics but a real "race version" should have a completely different suspension setup, better brakes, much more downforce and usually a higher reving engine (if it's not a factory spec series) and of course full slicks plus the rain tires.
Keep working on it and please get someone on board who does the physics, because this car deserves a snappy race suspension, sticky tires, powerful downforce to enjoy the fast corners of the Nordschleife and powerful brakes that slow you down before the next tight corner.
More power isn't really needed, maybe even less power and a broader powerband with higher revs.
Keep on!
