    I would like to try even more rubber at the front on my 430 Scuderia. To day I am on 245/35-19 on the original 8" rims and that is as wide as these rims will take me. At the rear I would like to stay on 285/35/19.

    The tire options I would like to use is Pirelli Trofeo R and they come in 265/35-19 or 165/30-19 but in order to get these on the car I will need a wider rim. Anyone ever tried this? What rim options is there. I know that some people weld/modify rims, is that even an option?

    I wouldn't trust a cut and weld job on a Ferrari that gets driven properly. The chance for the wheel to fail is a risk I wouldn't recommend.

    I agree, welding didnt seem lika a solution too me eather, but who knows... I have tried finding something/anything that would work, but locating a 9" rim with an ET of about the same as original (ET 44 or simillar) isnt easy. Ther only option seems to be to build specific 3 piece wheel.

    Try the new BBS RI-D wheels for the Scud! They just released them for the F12, 430 and 458.. These are the specs for the F430 Scuderia:

    Rear 19 x 10.5 offset +35
    Front 19 x 9 offset +28

    Your 265 tires will fit fine with these wheels, and its the lightest wheel :)

    The BBS FI wheels are 8.75 wide and work with the standard factory lugs. Great looking wheel on a scud and lighter than factory! Perhaps does not work for some other reason?

    That sounds like the best option. Didnt know they made them in those dimensions.

    Curious as to the differences between the RI-D and the FI wheels. Sounds like the RI-D are just the newer and maybe improved version?

    I was told the BBS Duras are NOT available for the Scuderia. It's a lighter version of the fi made of a different alloy.

    Can anyone else confirm the availability for the scud? Did bbs also fix the offset so it doesn't rub like crazy?

    Johan- The NF1s are center locks and 9" wide. The bolt on equivalent NF2s are 9" wide, too, and the ET is 28 mm. Just sold a set. They are very heavy wheels, though, and there are dozens of other wheels out there in 9" width that will fit 360s-Scuds. Rears on those Novitecs are 12-12.5", though, and require much bigger rubber.

    If you widen your front wheels and tires and leave the rears stock width, you may upset the balance of the car and push it towards oversteer, not always a good thing. Especially if it is wet or slippery.

    The RI-Ds are made from duralumin, which is the lightest material available in the market.. and if you look closer, the spokes are thinner than the FI wheels.

    From the BBS distributor here in Philippines... they're bringing in a set for the scud and for the 458.. also saw the BBS ad in a Japanese magazine I got called Genroq. Nice wheels but I'm not sure about the 9" width in front, it should run with a 265 tire so it won't be undersized but isn't it too wide for front tires? And I don't want to have any rubbing issues...

    yup you have to order it from them unless you have a BBS dealer there that you know, if you want them order it right away. I ordered these for my BMW 1M and its 6months already and I haven't got it! They said it takes a long time to make it and very high in demand so it will take awhile. But still I'm sure its all worth it... its 40lbs lighter than my OEM BMW wheels! Its way lighter than the BBS FI. :)

    "Upsetting" or changing the balance is what I am after, I actually want more oversteer. What I am looking for is a track setup. Today the car still understeers badly even though I have 245/35-19 in front with the 285/35-19 at the rear. I would like to see if I can get around the tracks faster and with more balance with wider tires at the front...

    A rear sway bar is one way to reduce the understeer.
    Be careful with your experimentation though. Severe bias will cause you to spin out VERY easily. I hope you don't test your progress on public streets, for your own safety.

    No disrespect, but if your car is understeering that badly even with 245 wide in front you may be loading/unloading the suspension into the turns incorrectly. Not criticizing, just putting an idea out there that a track mentor may help you out as well.

    I am more or less only using my 430 Scuderia for track days. Only drive it on public roads to and from the tracks. I find it almost impossible to take the 430 Scuderia to the limit on public roads and trying to evaluate the difference of 245 or 265 on public roads would be even harder...

    I dont think the car is under-steering badly, I am only trying to cut a few more sec on the track.

    A rear stiffer sway bar definitely be one way of reducing understeer. I have however not found anyone that sells a stiffer sway bar for the 430/360. I think Novitec Rosso offered one, but no longer...

    I have the Novitec wheels on my 360 and they have a 255 on the front, they are fine, however had to roll the fenders, 265 might be just too much.

    On a F430 GT2 they run something like 300mm wide tires in front and 310mm at the rear, 10mm diff front to rear. I guess that's where the under steer starts to disappears ;-)

    I want to keep the difference as small as possible between front and rear. Right now I am thinking about trying to fit a rear rim in the front as well. 10" front and rear with 285/35-19 and 265/30-19, Crazy, I know but that should probably solve my under steer ;-)
