    Bummer! I just found out both are designed by the same person. It would have been a perfect match!

    Took her on a highway trip yesterday, people could not believe there is a Ferrari on the highway with winter traction. Had to visit some areas with very choppy roads and while no terrible potholes, many sunken manhole covers. Absolutely no problems, this is the perfect winter setup.

    From everything I have read on this and other threads, is it correct to say that changing this car's wheel diameter will not cause any problems to its firmware, ie ABS/ESC/etc, or hardware? I'm not gonna ask the dealership because their response will always be: if you don't use the oem sizes, it's gonna cause problems to this system and that system blah, blah, blah.o_O

    BTW, is it safe to elevate the front more than the rear with the tire's sidewall? Hopefully at speed the car is not going to do an airborne back flip like the Mercedes CLR's in the '99 LeMans.

    The difference between OE f/r bias and the new f/r bias is within what the system is designed to work with, so no problem.

    As for raising the front higher, well, you don't. Yes, you change the rake about 3.8mm which is hard to even see. You increase diameter of both front and rear. The car rakes forward a lot more than those few mm, so you would have use a really BIG front to raise the front higher than the rear, so no, you won't make a "Mark Webber" as with this new setup, the car will still rake forward.

    What kind of speeds are you talking about? Around here you would never exceed 110 and that is for a fraction of a second because you've over cooked it. I can tell you I had the car above 100 yesterday with zero issues. It was next to a Lusso on stock tires and there is really no noticeable change to rake, but good to think about this.

    Here's the stats on the rolling diameters:

    Stock
    Summer ratio of front to rear 245/35/20 295/35/20 rolling diameter is 5.01% greater at the rear

    Winter ratio 235/35/20 285/35/20 is 5.36% greater at the rear

    OZ Zeus
    265/35/20 315/30/21 ratio is 4.32% greater at the rear

    I did the front/rear rolling diameter calculations when I was choosing tyres for my summer wheel setup with the OZ Zeus. As you can see, my Zeus setup is running less diameter at the rear than OE ratios and it has not presented any drivetrain or handling issues at all.

    If I’ve done my maths correctly, that’s equivalent to 2.5mm less rake vs the OE summer tyre setup and 3.8mm less than the winter setup.

    So, has anyone found the answer to this thread? will a 19 clear the brakes? the 458 challenge car runs on 19s?

    Yes 19" wheels will clear the brakes. What are you looking to do? Winter wheels?

    Well I'm hoping to run a set of Michelin all season 4, so I'm hoping to hit a 19x8.5 ET 45 on the front with a 245/40/19, while running the 20x10.5 ET50 in the back using the original 295/35/20. The temps in my area most of the year hover around 8-17c, especially in the Spring and Summer, and around freezing during the evenings. So my plan is to get a little bit more sidewall in the front, while running a compound that much more pliable in during the other 3 seasons. As I find Pzeros to be very waxy below 16c.

    Anyone try this?

    In that case, save yourself the trouble and use 245/40R20 and 275/40R20 on the OE wheels.
    Ask Caeruleus11 about that size. It works, and it works well. It will have the same profile as you are looking to have on the 19's.

    Depending on how sporty or winter-able you want them, either of these should do nicely.

    The Vred's are the most "all season" of the bunch, while the Conti, Yoko Goodyear and Pirellis are the more sporty.

    All are Y rated.

    So plenty to choose from without resorting to 19's.

    Yup! Those are the sizes that should have been spec'ed by Ferrari in the first place.

    Nah. What they should have done was to fit it with 275/35R20 and 315/35R20 on 9 and 11 inch wide wheels.

    Indeed, those 812 sizes will have the same amount of sidewall at the front as 245/40.

    Yep but more importantly, with a lot more volume. They would run at a pretty low pressure by comparison and thus be great at absorbing jolts. You could easily drop the pressure 4-5 psi compared to stock, and gain a softer tyre with a lot more protection. With the correct offset it can be done. Have seen a few FF's with 812 wheels and tyres.

    I went and did it, 19s front with a 245 40 19, dramatic increase in daily driveabikity, slight decrease in steering feel, but well worth it.

    I’d love to know!

    I’d also note a friend with a Delta Integrale on his very first drive within 5 minutes had a flat. So that is not a solution to flat tires. The solution is better roads. That is my rant for the day carry on!
