New Wheels on Lusso

Sweet. The ride height looks pretty good already - it certainly doesn’t look stock. What are the widths and offsets of the wheels?

BTW, you might want to check the load index of your front tyres. The minimum load Index for the FF is a 95 and I assume it’s the same for the Lusso. When I was shopping wheels and tyres, I couldn’t find a 255/30/21 which met the load rating. Only the 265/30/21 and wider would meet the rating. It might not be an issue for you in the states but it’s an insurance problem here in Europe if you have an accident.

 

Cool. You’ve got room on the front rim to size up to a 265/30/21 if you decide that you need to for handling or insurance purposes.

 

Doubt very much the 265 will fit with that offset. They will need an additional 10 mm on the outside compared to your setup as a bare minimum. Not seeing that happening without rubbing.

Not sure there's a whole lot to gain from it. Those rears are vastly wider that the fronts. To get where you are in terms of balance, at least 285 if not 295 fronts would be needed to counteract that much rear width.

Would like to know how much weight has been added with those. There's a lot of rotating mass in those rears. Cannot see how the car would become faster with both more weight and diameter.

I think you make a good point regarding the load rating.
I would not like to be in that boat if there's an insurance issue. If the car hits a small pothole and has a blowout causing the driver to lose control, insurance can easily turn their back on that one, as the owner has installed insufficient tyres on the car. Those tyres will not like a pothole one bit, so on a car this heavy, for me it would be a real concern - and I'm usually not too fussy about these things.

Not trying to tear it all apart and be a downer, but I cannot fathom what goes through the wheel vendors heads when doing these setups. They are the definition of more show than go, sorry to say.

Wondering about the stance and appearance of your car with the stock wheels for comparison. I would venture to say that it is currently better in appearance than with some of the stock Lusso wheels that is why I chose to switch to F12 wheels. Any "before" pics you can share? I will try to find some as well. Joe

 

F12 wheels on a Lusso? What are you running for spacers in the back? 25mm?

The F12 wheels are a nice setup for a Lusso though. Should handle great if teamed up with 812 tyres or at least 265 in the front along with the 315 rears.
There are two Lusso's in my area running 812 wheels/tyres and they are very happy with that setup. Fills the arches great with those 275 fronts.

For summer tyres, Ferrari calls for 95 and (Y) speed index. Your tyres are 93. For winter tyres it calls for 92, but that is winter tyre specific, and it reduces both load bearing capacity and maximum allowed speed.
I'm sure you'll be fine and most of the time you are probably within the capabilities of the tyres. My point was just that you're taking a risk from an insurance and legal standpoint, and running such a low profile on a heavy car leaves little room for error.

If you like the look, great. Just keep in mind that you are running those tyres close to their limits.

Stay safe.

The wheels look great and I’m really pleased for you. What I’m less pleased about (and Il Co-Pilota was a bit less diplomatic than me) is that as a self proclaimed novice, you put your trust in professionals (the custom wheel guy) who set you up with wheels which could invalidate your insurance.

That’s just not on. In my business, that’s a breach of fiduciary duty.

I bet they didn’t discuss the minimum load ratings of the wheels with you either did they? I see lots of wheel vendors on FChat selling F12/TdF/812 wheels to FF and Lusso owners without being clear that the wheels are not rated for the weight of the car and that it’s on the owner’s risk to buy them.

 

I’m also still struggling to understand why your custom wheel guy didn’t put you on 265/30/21 tyres in the first place. The rear 335/25/22 are 1.8% taller than stock. The front 255/30/21 is only 1% taller than stock but the 265/30/21 is 1.9% taller than stock which is almost a perfect match for the rear.

As Il Co-Pilota says, there’s a risk of rubbing if you put 265s on the rims you have unless the rims can be sent back to the factory to have the offset increased by a few mm.

 

That's the thing about all of this. Yes I'm a bit brash and not very diplomatic about these things, but boy am I also fed up with wheel vendors taking advantage of people.

Like you said, what about wheel weight limits? Too many are so damn focused on either design or weight that they don't give much thought to this, especially in the US where these laws are very lenient. Some time ago, a member here asked me for some assistance regarding a set of 458 wheels by a manufacture whom will remain nameless. He had inquired about a forged monoblock wheel and wanted it light. The manufacture assured him that it was fine and that it would be fine tracking the wheel. They offered fronts around 16.5 lbs and rears around 19. I contacted the manufacture with some questions regarding TÜV certification etc. And they reassured me that they had it all in order. Did a bit more digging and asked for confirmation, which never materialized. Then a few days later they bypassed me and asked the customer for payment and a go-ahead. While doing this they also urged their client to keep me out of it all, as I was just pedantic and causing unnecessary problems. From that point on, they ignored my emails and phone calls. The guy who was buying the wheels asked me to write a letter asking for a few tech specs. There's what came back. The front wheels had a load rating of 270 kg and the rears around 300 kg. That is just absolutely nuts. They even had the audacity to tell the guy that it would be fine and he needed not worry. I cannot for the life of me understand what goes through the mind of that kind of moron. That is playing games with peoples lives.
Needless to say that the buyer pulled out of the deal. Unfortunately he had one hell of a time getting his deposit back and I received a slew of nasty emails.
If the buyer chimes in with the manufacture name, fine, but I won't disclose it without permission.

The moral of the story simply is that do your homework and find an unbiased source to ask for assistance if you get stuck on something. If you use the load rating of the manufacture as a guide, and use a manufacture with TÜV approval, then there's a good chance of a successful purchase. I'm well aware that TÜV is a European thing, but if not only the wheel but also the manufacture is held to European and Japanese standards, there's some kind of governing body looking into the manufacturing process. That's why I like HRE and Forgeline, they adhere to these manufacturing standards.

Then there's the whole performance aspect of it all. Vendors whom are perfectly fine telling trusting people that the.setup is a performance enhancement. More often than not, they also claim that comfort remains unaffected. I mean, wtf!? How do you half the tyre profile, lower the car on 35 mm, add weight and width, and yet have an unaltered level of comfort? That's just taking the piss frankly. I've personally asked Mario Rill from Novi if their springs affect comfort, and the answer is absolutely. He even went one further and mentioned that their springs were not intended for track use and that he would advise against it.

I'm not targeting these boards specifically, but more the general issue in the fact that all over the place, being it online or in stores, vendors are fine selling people "upgrades" based on false info. How can a car like a 488 for instance, which already suffers from way too much understeer, benefit from rear tyre that are 5 cm wider than stock, while keeping the stock 245 front width? Yes, if the car is a cruiser and all you co is the occasional green light stab, fine. No harm in a visual personalisation. But don't sell that same setup to someone who asks for better handling or better tra k performance. That is just not okay, and vendors doing so should look into what ethics and customer care means. Unfortunately it is not trendy and popular to tell people to get 19" wheels, so that only gets brought up by actual race shops who seek to really make the clients car faster on the backroads or track.

A bit of a heavy rant for a Saturday evening I know. I prefer to be positive and helpful, but this is something that I feel needs to be brought up on occassion.

To anyone who prefer the big wheel look, have at it. Just do your homework and be mindful of what ever compromises such a set up might have.

Same goes for the any fellow track rat seeking to enhance the cars performance potential. Being it a Lusso or a Pista, a Caterham or a GT4. Seek out the local track warriors and what ever shops they use. The laws of physics always apply, and nothing will ever change those.

I would go as far as saying that the vendor should at least have recommended 275/30R21. Would fit well on ET45 on 9.5" wheels. Then you get into a width that sort of starts to work with the rear width and a good load rating.
