    I think the offsets look fine in my opinion. But the front fender rubbing is a SERIOUS problem and should be fixed immediately. You will need to raise the car up a few turns since the lowering is the cause of the fender rubbing. Then roll the fenders in professionally.

    If you let this go, the fender will crack and now you're talking BIG $$.............ask me how I know haha

    What size tires and wheels do you have? My new 19 inch Challenge Wheels have no problem with front scrub. My tires are 225/35/19 front and 285/35/19 rears. Wheels front 7.5J x 19ET (31.5mm) Rear 10J x 19ET ( 39mm). This size was on 360 Challenge Stradale and F 430. Both rear and front appear either offset improperly with is too wide.

    Please post tire and wheel sizes and offsets. From the angle of the pictures, the rear offset looks like it is too aggressive, while the front is OK, yet you are catching the front fender. The car does not looks too low. Is the suspension stock?

    My tires are 235/35r19 in front and 305/25r20 in rear. I haven't had any rubbing on the front right since Ive had the car. The fender marks were there when I bought the car. It has a stock suspension. I dont know the offsets of the wheels.

    You need to roll the fenders. Stradale and f430 the fenders are rolled from the factory because if this exact problem.

    Roll the fenders and drive with no issues :)

    Your combo set up may be too aggressive for stock suspension. You will definitely get into trouble without front lips being rolled with such a wide front tire mounted on 19's. Your combo with 20's on the back and 19's on the front may affect the way your ABS functions.
    and overall handling, as you have altered OEM geometric setup. I would have this setup checked by your Ferrari Dealership. This setup certainly changes cars understeer/oversteer characteristics. The 19" Challenge wheels sizes that I mentioned in prior post do not require rolled lips nor do you need to change stock alignment settings. I would not trust the sellers knowledge on this combo without firsthand Ferrari Mechanic giving his blessing as the Modena at it's limit can be a handful.

    If the 18" starfish wheels and the 19" Stradale wheels are the same offset, why are Stradale front fenders fenders rolled? On paper the 19" front tire is 0.4" shorter than the 18" front tire, but is 0.4" wider, which is 0.2" per side (inboard / outboard). I'm surprised the clearance is that sensitive to the tire's sidewall being 0.2" closer to the fender lip, unless the Stradale suspension is lower?

    Don't roll the fenders that will brake the weldings,its better to trim the inner part with a Dremel cutting disc I made this in a 430 and it worked perfect Wolfgang from Novice told me that some years ago.
