After Market Maranello 550 Wheels

This tells me it's doable. Try asking someone like Damian or Craig, Ferrari-Tech or Calder1, how.

To fit wheels made for a rear engined Ferrari on a front engined Ferrari you will need quite thick spacers in the rear, as the offsets are quite diffrent.

 

just what the v12 needs.... less tread in the rear....

 

I personally think that the 599 GTO wheels would look absolutely fantastic on a 550...

 

Hi

It's just some calculating

Let's start

1 inch = 25,4 mm
original
front 8,5 inch = 215,9 mm
rear 10,5 inch = 266,7 mm
half measure is
front 4,25 inch = 107,95 mm
rear 5,25 inch = 133,35 mm
this would be offset 0

550 original
front 8,5 inch offset 43,65 mm (measure from hub surface to outside = 107,95 mm - 43,65 mm = 64,3 mm)
rear 10,5 inch offset 32 mm (measure from hub surface to outside = 133,35 mm - 32 mm = 101,35 mm)


i have mounted spacers 16 mm front and 30 mm rear, there is enough space.
so offset change to
front 8,5 inch offset 43,65 mm - 16 mm = offset 27,65 mm (measure from hub surface to outside = 80,3 mm)
rear 10,5 inch offset 32 mm - 30 mm = offset 2 mm (measure from hub surface to outside = 131,35 mm)


possible spacers with original rims, i will try this when my ordered 42 mm spacers arrive in the next 2 weeks :
30mm front should be possible - i will try it next 2 weeks
42mm rear should be possible - i will try it next 2 weeks
so offset change to (this should be the maximum possible offset with the original rims)
front 8,5 inch offset 43,65 mm - 30 mm = offset 13,65 mm (measure from hub surface to outside = 94,3 mm)
rear 10,5 inch offset 32 mm - 42 mm = offset -10 mm (measure from hub surface to outside = 143,35 mm)


So the rims you want to mount must have
front is like the original
8,5 inch with offset between 13,65 mm an 43,65 mm (smaller offset means rim is more outside)

rear is not as original
11,5 inch = 292,1 mm
half measure is
rear 5,75 inch = 146,05 mm (this would be offset 0mm)

this means
the measure from hub to outside could have from 101,35 mm (like original 550 rim ) to 143,35 mm (like original 550 rim with 42mm spacers)

so the 11,5 inch should have offset 44,7 mm (looks like original 550 rim ) to max. 2,7 mm (looks like original 550 rim with 42mm spacers)

I put the 19" modular wheels that were optional for the 575 on my 550.

No mods needed and I like them a lot.

They sometimes are hard to find for sale, but do show up on eBay or FerrariAds once in a while.

Sharp wheels, Ron. I like them better than the Barchetta modulars.

They are sharp wheels Ron!
I also tend to like the look of the 575 modulars, but I like to think of the 550 modulars as period correct & I like the fact that they are deep dished for the rears.

 

I like the look of both the 18" 550 modulars and the 19" 575 modulars.
I went with the 19" to give my 98 550 a slightly more modern look.

I kept my original set of 550 standard wheels for the next owner.

 

Right, but they would not fit.

 

The best looking wheels for the Maranello.

 

The bolt pattern of the 360, 430, 456, 550, 575 is the same.
It is different from the 612 on.

 

If you order them from BBS in 5x108 they will

 

Hi Gary

The spacers you choosed, means about 5mm secure from my expected limit.
If you wait 1-2 weeks, i can send pics with 30mm front and 42mm rear with the original rims, so we can see if this is really the limit which will be able mounting at a Maranello.

I have found this pic at the net.
This was the impulse to order the 42mm spacers.

This is my 550 with 30mm at the rear and 16mm at the front.
You can see that there is some space to the blue 550.

One question i ever missed and so it was never answered :

What is about the stability of other rims?
The 550 has a weight of about 1750 Kg.
I think the 360 or the 430 is lighter.

do the 360 or 430 rims have the same stability like original 550 rims.
The tires for the 550 have a weight index of 99.
What index have the 360 or 430 tires ?

I think this is important, the 550 is heavy and fast, broken rims would be not fine.

Have mounted the rear spacers with 42 mm, the front is always with 16 mm, think my car is to deep for the 30 mm.
