Widest rim size for the rear of a 575

Oh, forgot to say that they were used.

The rim wells from all 4 rims had deformations, some of them you saw with the eye and rim on the ground.
Even my wife without technical knowledge saw the deformations without showing them her first.

The seller took them back, but then he asked me to buy them for a better price after that he let them rebuild.
I said no.

Thanks for the link.
I know the 345/30 from Terry.

Perhaps 1 day I will buy these sizes to get them on the 550, perhaps not, I don't know.
First the 599 GTB to GTO wheel project have to be finished.

Why did you pull the NF2s? I have a set with brand new Pilot SuperSports mounted. Had them 2 years now without getting them on the car to try out. Sure hope I like the ride...'cause I really like the look...

 

Johnny- The 19" modulars finally grew on me after close to 7 years of ownership. Nearly 13 years now.

With FHP, the NF2s rode kind of rough at the rear, especially with those rock hard Pirellis. Undoubtedly much better with the MPSS tires.

 

Taz, is it possible/advisable to lower the car a little based on the original suspension? I’d like to get rid of some tire/fender gap without the trouble of changing the entire suspension.

Attached is a picture, I already had the spacers installed you had suggested. I also had the F1 transmission converted into a manual with all off the shelf original parts.

Lowering with original springs is possible.

Pete and the team at Universal Autosports are incredible. This conversion has gone by with ease. For me, I was able to find my “dream spec” 575M in impeccable condition and the luck to get it updated in manual form.

 

Thank you for the response.

 

Steven- You can safely lower her about 15-20 mm using the stock suspension ride height adjustments. After that you need a 4 wheel alignment of toe and camber, which do change when she is lowered. Lower her any more than that and you will get the shocks our of their optimum operating range.

Glad your 3 pedal conversion went well. Can you share her VIN with us?

I see she has the CF option on her from the steering wheel. Did you find a CF shift knob, as well? Interestingly, the shifter plates on CF equipped 3 pedals had the shift pattern since it was missing from the shift knob. Regular 575s had plain shifter plates since the shift pattern was on the knob.

 

Rears came in 19in and 20in sizes, and at least 3 different offsets (ET46 (20in) vs ET51, and ET56 (19in))

There is a pair of 20in 12.5 rear wheels for sale on ebay in black (no affiliation; same seller did advertise on Fchat a while back, though):

https://www.ebay.com/itm/Novitec-NF2-20-Rear-Wheels-Fits-Ferrari-360-430-550-575/273821857950

Finding single wheels is extremely hard (still looking myself)

Tire selection may be better in the 20in rears, but haven't looked recently.

 

Last time I looked, the F430 NF2s were 12.0", not 12.5". Here are the ETs on the standard 360/575M NF2s. Not sure what they are on the 20" NF2s.

Novitec NF2 (Not OEM) Five Spoke, 19”, 5 X 108 mm

Front 9J X 19 ET 28 mm, Rear 12.5J X 19 ET 51 mm

 

Not entirely accurate:

19in wheels came in two production variants (the first two being the rarer version)
Front: 9Jx19 ET33 5x108 (Novitec PN F436002-ZV)
Rear: 12.5Jx19 ET56 5x108 (Novitec PN F436004-ZV)
Front: 9Jx19 ET28 5x108 (Novitec PN F43600x)
Rear: 12.5Jx19 ET51 5x108 (Novitec PN F43600x)

20in rears came in both 12 and 12.5in versions. I don’t have any documentation of the offset of the 12 inch version. Here it is for the 12.5in (Et46)

I am not sure if a pair listed on eBay are 12 or 12.5in; the seller states they are 12.5, but does not have any photos of the markings on the back of the wheel spokes.

(FWIW, still looking for single 19in wheels of either production version...)

 

While I’m at it, Hamann PG wheels also came in 4 sizes. Unlike Notivec (Fondmetal? contract) whose offset appears to vary on production run, Hamann (Oz contract) appear to all have unique part numbers.

9J X 19 H2 E28 PN 67013006
11J X 19 H2 E40 PN 67013007
13J X 19 H2 E53 PN 67013009
11.5J X 19 H2 E34 PN 67013010

 

Thanks for the update. Mine were the ones I documented and were very late in production.
