Nice cars, and welcome. get ready for some "how much is our discount" questions 
Actually, I offer great discounts on Group Buys, or production pre-orders. By exemple, I have only one Sport kit left. before I start another batch of 10 units, I will offer members to jump in in a pre-order GB. Usually a 10 to 15% discount on installation kits (hats, brackets, fasteners, hydraulic adapters). I sell Wilwood parts separately, and therefore it is possible to buy only an installation kit, and buy the rest later, or from your cousin who happens to have Wilwood licence.
