Are aftermarket wheel spacers safe for a Ferrari 360 Modena?

Just sharing my experience: I went through this last year and was SUPER paranoid about safety too! Honestly, I spent weeks researching before I pulled the trigger.

1. H&R Trak+ Wheel Spacers 15mm - I loved how light these were, but I was lowkey worried about the bolt quality for track days.
2. Formula Dynamics Wheel Spacer Kit 15mm - Ended up going this route cuz they specialize in Italians and the quality is amazing!!

Seriously, the flush look is fantastic but definitely check the torque after a few drives tho! gl!

Honestly, i get the hesitation cuz I'm pretty cautious with my own 360 too. I personally wouldn't go over 15mm—it's like the absolute limit before u start worrying about bearings. I went with the Hill Engineering 15mm Type 2 Hubcentric Wheel Spacers and they've been solid. Just make sure u get the Hill Engineering Extended Chrome Wheel Bolts to match or it's a safety nightmare. Honestly, as long as theyre hub-centric and torqued right, it's fine for street use... idk about heavy track work tho. gl!

For your situation, I've found that keeping things hub-centric is non-negotiable on a 360 to avoid that annoying highway shimmy. Honestly, the 15mm setup is the sweet spot for that flush look without destroying your scrub radius.

* Go with Novitec 15mm Aluminum Wheel Spacers—the fitment is basically perfection.
* You’ll definitely need Novitec Titanium Extended Wheel Bolt Set to maintain proper thread engagement.

Technically, it does add some leverage to the bearings, but I mean, if you're not tracking it every weekend, you wont notice any real wear issues. Just torque 'em to 100 Nm and you're good to go!!

Ok so I totally get being nervous about the cost and safety!! Honestly, I was in the same boat when I first looked at spacers for my 360. For your situation, I'd say you don't actually have to spend a fortune to get that flush look safely. Just make sure you get a high-quality aluminum set and definitely dont cheap out on the bolts—those are the most important part! 15mm is amazing for the stance, but seriously, just double-check the torque specs after a week of driving. It's such an easy way to make the car look even better without breaking the bank lol. gl!

Seconding the recommendation above! Hub-centric is a MUST or youll get crazy vibrations. Honestly, I'm a bit paranoid about safety on track, so I always worry about the bolts. IIRC, some people say to check torque every few hundred miles with spacers.

* Use high-quality steel or titanium bolts
* Double-check the seat type (ball vs conical)

Not sure about the exact bearing stress tho, but keeping it at 15mm is probably fine. Better safe than sorry!

Late to the thread but I figured I'd weigh in since I've had my 360 for over ten years. You really have to be careful with the suspension geometry when you add spacers. It changes the scrub radius and that can honestly mess with how the car tracks under heavy braking, so make sure you're ready for a slightly different steering feel.

• Check your bolt seats. Ferraris usually take a ball seat, but many aftermarket kits come with conical bolts. Mixing those is a recipe for disaster because the contact patch won't be right.
• Give Eibach Pro-Spacer 15mm Silver Aluminum a look. I've used their stuff on other builds and the metallurgy is top notch for heat dissipation which helps if you're doing spirited drives. Anyway, I'm getting to the point where my back acts up every time I climb out of those low bucket seats. My wife keeps telling me to trade it for something more sensible because we can't even go to our favorite Italian place anymore without me worrying about the driveway incline scraping the front end. I spend more time looking at the pavement for potholes than the actual scenery these days... but yeah, just don't skip the hub-centric lip and you're good.

Building on the earlier suggestion, I actually had a bit of a rough go with my own setup recently. Honestly, I thought going hub-centric would solve everything but unfortunately I still dealt with some really annoying vibrations once I hit highway speeds. It turns out the tolerances on the ones I got werent quite as tight as advertised, and it really messed with the steering feel. I was pretty disappointed because you expect high-end parts to just work, but the reality is sometimes they just dont play nice with the factory hubs. I learned the hard way that even a tiny mismatch in the bolt seat or a bit of grit on the hub surface can cause a huge mess. My current setup is finally feeling smooth now, but it took way more trial and error and extra shop time than I ever intended. If you are gonna do it, just be super careful about checking how the spacer actually sits against your specific wheel before you torque it down. It is so frustrating when a simple mod turns into a mechanical headache... but dont let that discourage you, just stay on top of the details.

Finally someone says it. Ive been thinking this for a while but wasnt sure.

Same here!
