Puis-je ajouter ou modifier des options personnalisées sur ma commande ?

As mentioned on the cart page, in most cases, it is not possible since we start proceeding with all orders as soon as they show up in our system:

” Please verify the product configuration above. Once the order is placed, it will not be possible to make any changes or cancellations of the order.
All wheels are custom-assembled according to your order returns and refunds are not applicable for this product.”
