Weight comparo: HDK vs Stock

Mustang II spindles.....they are beefier than the pre '73 spindles...and you can always upgrade to the Wilwood Pro spindels....the GEOMETRY is based on the Mustang II front steer spindle with an added 1/2" to improve roll center and lessen camber gain on some applications.

I'll bet the Wilwoods will give him all he can handle
You have done your home work Denny and your setup is top notch! For a car using your setup for autox, some agressive camber gain from ride height to bump would be the frosting on the cake is what im getting at. A taller spindle is one way, and a shorter upper ball joint stud is another. I dont know how much of either will reward a guy with how much camber gain. A solution to this would open an even larger market for your setup. The Pro spindles available in different heights?
