Performance Design orders are shipped via UPS.   Domestic freight shipments beyond the limits of UPS are shipped LTL freight.  International freight shipments beyond the limits of UPS are shipped via the international freight forwarding company which will select the best carrier for the region and time frame allotted. Performance Design will not ship on a customer’s shipping account. Shipments are FOB Origin and Performance Design will not deliver without a signature or instruct a carrier to “leave on porch” or otherwise.


Many Performance Design products can be ordered with custom features or requests.  These orders must be paid in full prior to the manufacturing steps that would “customize or modify” the product beyond our standard products.  The stage this payment must be made will be determined on a case by case basis.  Upon implementation of these features the order is non-refundable.  Special orders may incur additional fees or charges based on additional materials, manufacturing and labor costs, design hours and tooling charges.  An estimate of this cost will be provided as a budgetary estimate or a quote depending on the nature of the work. No cancellations, refunds, exchanges or credits will be honored for any special order or custom-built items once the customization portion has commenced.


All special order items will be processed in the most efficient and timely manner possible, however one-off work can experience delays or disruptions from suppliers so timing will only be estimated.  Performance Design cannot and will not be held responsible for delays beyond their control. The approximate time of arrival is only an approximation and not a guarantee. Performance Design will not be held responsible for specific ship-to or receiving dates of your special order. Refusal of a special order shipment does not constitute any right to a refund of any kind whatsoever.


1. Performance Design will periodically contact our customer database to provide current customers with product information about new products, company events, services and news.  We will immediately honor any request to be removed from any email list.

2. Performance Design also maintains subject specific email lists that focus our contacts to subjects for sub-sets of our customers and fans.  Most of these lists are permission based and generated because of a request to subscribe, however occasionally we may add some customers to a specific list for reasons of a prior purchase, a prior request for related products or services or mandatory distribution (ie: dealer updates for our product resellers).

3. Performance Design will not share our contact list with 3rd parties to allow them to email content generated by the 3rd party.  Performance Design does use a 3rd party email service to contact customers with Performance Design generated content only and selects this 3rd party based on their services, security and other benefits.
