The Ferrari Purosangue extended wheel bolts are standard components to secure the wheels when adding wheel spacers. A wheel bolt features a threaded stem attached to a conical/ball seat that matches the wheel insert. Simply, they go from the wheel through the brake rotor cap and directly threaded into the vehicle hub, locking everything in place. Any time you run slip-on Ferrari Purosangue wheel spacers, you need longer wheel bolts. If you have installed wheel spacers and used stock wheel bolts, don’t be fooled by the fact that visually the wheel is securely fastened. Actually, the thread of stock bolts is only enough for fastening the stock wheels, when putting a Purosangue spacer between the wheel and vehicle hub, the thread won’t be enough anymore. When your Ferrari Purosangue is loaded to capacity, an emergency maneuver performed at high speed may lead to a bolt failure.

Choose Ferrari Purosangue Wheel Bolts With Right Seat Type

Equipping your Ferrari Purosangue with the correct wheel bolts is very important to ensure the safe and reliable mounting of the wheels. Common seat types of the Ferrari wheel bolts include conical seat, ball seat, flat seat, etc. Most Ferrari Purosangue stock wheel bolts are conical seat. If you use current wheels, just keep the same wheel seat of extended wheel bolts. But if you upgraded to aftermarket wheels, then you need to make sure you have wheel bolts that will fit properly. If you have added wheel spacers, to meet proper thread engagement, the thread length of the extended wheel bolts should equal the length of stock bolts plus the thickness of the spacer. Giving an example, if your stock bolt’s length is 27mm, and you have installed 10mm spacers, then 37mm wheel bolts will be required.

Choose High-Quality Ferrari Purosangue Extended Wheel Bolts

Wheel bolts are very important parts that apply a clamping force to secure the spacers and wheels. If the wheel bolts are not strong enough to support this force, they will likely be bent by road impacts. Use wheel spacers with high-strength wheel bolts to ensure the wheels are safely fastened.

Properly Torqued Your Ferrari Purosangue Extended Wheel Bolts

Since wheel bolts are designed to fasten your wheels with a clamping force. When torqued to the manufacturer-specified spec, they will make a strong mechanical connection to the threads on the vehicle hub. It is very important to ensure your Ferrari Purosangue wheel bolts are torqued to the correct specifications. If a wheel bolt is undertorqued, it can continue to loosen itself through the vibrations while driving. As a result, it will unseat the wheel from the hub and create additional vibrations as it spins erratically. This can put pressure on the bolt itself that it was unable to handle, leading to eventual failure, even if the bolts haven’t slid off first and the rim hasn’t separated from the hub completely yet. Over torquing can have similar effects. Stretched wheel bolts can lead to warped brakes as loads are distributed unevenly across the hardware. The previously-mentioned cracking and shearing can also separate the bolt from the hub, and potentially lead to catastrophic wheel loss. It is recommended that check whether the wheel bolts are fit correctly or not by spinning the wheel while it’s off the ground, making sure it has 360-degrees of rotation.
