I think you missed a combo: Sport Cup 2s in 235/35 ZR19 and 285/35 R20.
This combo results in 0.3" taller front tire with (obviously) no change in rear. A 1.2% change in rake. I really have no idea, but that feels like a reasonable setup, no? And if not, I wonder if the suspension has an adjustable height?
Yes, the OD of the 235-35-19 will pair with 285-35-20, since the front 235 is only 0.3" greater OD, and only raises the front 0.15"
But, you are widening the fronts 225 to 235, while leaving the rears at the stock 285 width.
Some on the forum think that the 570s has understeer, and could use wider front tires compared to the rears.
I have not found that to be the case, and would prefer to widen the fronts and rears proportionally, 235 & 295, or 245 & 305.
High speed oversteer is scarier than low speed understeer in my experience, so I would not under-tire the rears, especially with the HP.
