I know there's been a few threads about putting aftermarket wheels on the 456, and Novitec seem to be amongst the favorites. I looked at upgrading mine about a year ago, and almost went for a set of Novitec NF2s but found that getting tyres was near impossible. At the time, the supplier told me that he thought there would be new tyres manufactured in 2014, but when I recently contacted them, they all said no, discontinued as far as they were concerned. I have now started to look for alternative wheels, and actually quite like the look of the 430 wheels. The bolt pattern is the same and tyres should be more readily available. The front wheels are 7.5"J x 19 ET 31.5 mm, while the rears are 10"J x 19 ET 39 mm. The original 456 front wheels are 8.5"J x 17 ET 50 mm, while the rears are 10"J x 17 24.6 mm. Three questions; am I right in calculating that the above change will basically mean that, without spacers, the front wheel projects 0.22" further out than previously, and the rears are about 0.56" further in? Does this mean I simply add spacers of 0.56" to regain the original rear track? Finally, bearing in mind the reduced width of the front wheel, being 12% narrower, would I be significantly affecting the available grip at the car at the front, or would it not make any difference unless I was really driving it to within 12% of it's absolute limit? I'd very much appreciate any guidance you can all give! Image Unavailable, Please Login
I like the 430 wheels a lot, but even though I don't often drive my car hard, it is a front engined v12, and I was reluctant to put less than factory rubber on it. Didn't want to risk the under steer. They may not be as classicly pretty as the 430s, but I went with the OZs.
Some owners have tried F430 wheels on the 456/456M and most have changed back to a more suitable wheel set with wider front wheels. Those narrow wheels will affect both handling and braking. 575M 18" wheels work great on 456s and so do 550 wheels. Chris at Exoticar still has OEM new sets of 550 wheels for only $1200. Those look great and provide more rubber using standard Maranello tire sizes of 255/40 18 F and 295/35 18 rear.

I probably would have gone the 550 route, if the 19" Oz superleggeras hadn't popped up on eBay for $900.
I put the 575 19" wheels on my 456, used 10mm spacers in the rear, no issues and received many compliments. MB Image Unavailable, Please Login Image Unavailable, Please Login
Thanks for all the suggestions! I did wonder if the 430 wheels would have been a bit narrow! Taz, I really like the wheels in your first photo. Which ones are those? Christian, your's are really nice too. I'll drop Chris at Exoticar an email and see what he has available. Thanks again for the help!

Let me know if I can help.
Christian- Those are actually the 18" 575M wheels and they look great on 456s and 456Ms. CJB- Those are the F430 wheels. Look great, but too narrow up front. Would have fitted a set to my 575M if they had been wider front and rear. Novitec NF2s fit great (9" F, 12.5" R) and used sets are often available for ~$4K. New from Jason at Exotica Motorsports, a sponsor here at one point, they are $6200. Two shots of a 456M on NF2s and my old 575M wheels on a friend's 456M. Incidentally, there are several threads on this subject with many more photos. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
Your right, was over 10 years ago...forgot the OEM wheels were 17", not 18". I just remember going up one inch over the standard wheels. Regardless, made a huge improvement in the look and I also lowered the car about 1" as well. MB
575M wheels look great and weigh less than the 456/456M or 550 wheels. Probably not less than the 456/456M wheels after the larger tires are mounted, however.

Hi Gents, So I picked up a set of 550 wheels from Chris at Exoitcar, and wanted to know how to calculate the spacer size required to get them to fit my 456. Is there a simple calculation? Are there any geometry changes that need to be made to optimize the new wheels? Thanks in advance!
I went the same route and put 18' 550 wheels on my 456M. I put 15mm spacers in the back, which just about lines up with the fronts (no spacers). I think 20mm in the back would give it a more aggressive stance , but not sure how it would affect the drive/handling. Image Unavailable, Please Login Image Unavailable, Please Login
No spacers are required, but they look better with Hill Engineering Type 2 (spacer bolts to hub, wheel bolts to hardened inserts in the spacer) that are 25 mm on the rear. If you want to get really precise, here are the necessary numbers. Draw the wheel width out on a piece of paper and bisect the width for the zero offset point on both wheels. Ferraris are offset towards the outside of the wheel. Then draw in your offsets for the old and new wheels. Will show you the relationship from old to new. Be advised the original 17" wheels look better with rear spacers, too. I had 25 mm Type 2s on my original 18s and still have them on my OEM 19s. Note you already pick up 6.35 mm of extra outside width (0.25") on the fronts because of the difference in offsets. 456 GT/456M Five Spoke 17, 5 X 108 mm Front 8.5J X 17 ET 50 mm, Rear 10J X 17 ET 24.6mm 550/575M/Superamerica 550/575M Five Spoke/Modular 18, 5 X 108 mm Front 8.5J X 18 ET 43.65 mm, Rear 10.5J X 18 ET 32 mm 575M/575 Superamerica Five Spoke Modular 19, 5 X 108 mm Front 8.5J X 19 ET 43.6 mm, Rear 10.5J X 19 ET 32 mm
