430 F430 Wheels offsets vs Scuderia

What are you specing

 

@kenneyd helped me as I wanted something similar to his setup.his YouTube video was helpful.

I went with..

BCforged Rz21 Matte Gunmetal with OEM cap machining
Front 8.5"x19" +20 235/35r19 Michelin 4s
Rear 11.0"x20" +28 305/30r20 Michelin Image Unavailable, Please Login

When I weighted my stock wheels vs. the Scuds, I believe your weights are correct. I think they fit the wheel well nicely.

You and KennyD worked out getting 20" rims and another 20mm of tire width on the ground in the rear? You're my heros - but now I'm kicking myself for dropping $1K in new 19" rear tires within the last week...

This is a great site that I’ve used to spec wheels for many of my cars. You can enter a baseline wheel specification and a new wheel specification and the site will give you a comparison in terms of how much the new setup will poke out farther than the baseline and how much closer the new setup is to the strut.

235/305 is the exact same ratio as the stock 225/285 setup.
Your car will not know.
Not sure where your coming up with the 33mm number, it's 27" vs 27.1"

 

Essentially

Here's my data

Tires
Front: 225/35/19: 25.2"
Rear: 285/35/19: 27"

Base f430
Five (Ten) Spoke, Challenge Monolithic, Scuderia Style 19”, 5 X 108 mm
Front 7.5J X 19 ET 31.5 mm, Rear 10J X 19 ET 39 mm

Scuderia/16M

10 Spoke, Five Spoke 19”, 5 X 108 mm
Front 8J X 19 ET 31.5 mm, Rear 10J X 19 ET 39 mm

 

Mario, be sure you're not looking at "Scuderia style" rims, which were available for the F430 via the Ferrari accessories programme. These look identical to the wider Scud wheels, except they are the same width as the standard F430 wheel. Genuine Scud wheels are wider to clear the Scud's bigger CCMs.

 

Here they are, confirmed by real photos of real wheels.

Ferrari got them from different manufacturers, so no telling.

 

The factory wheels that were on my Scud were ET38 for the rear and ET31.5 for the front. I just checked.

I like the factory Scud wheels and would not have gone aftermarket except that I hit a small pothole which bent the front right wheel. My initial search turned up similar results to you. Scuderia 'style' wheels or factory wheels that were either in a fire or someone had welded back together. Slim pickings.

So I just bought some aftermarket wheels while I carried out my search for a replacement wheel. I hated to have the car just sitting there and not being able to drive it. I will likely get another wheel in due time and then sell them as a set.

 

I bought 4 rims from dealership new not long ago
Im sure they are available

 

I convinced myself that if Ferrari put that style of wheel on the 599 GTO then it would be ok.
