Torque should be above 300 ft-lb.

Think about it, you daily driver has Qty 5 lug nuts, each with 90 ft-lb. This is a single nut - ONE. What is really the kicker is the clamping force a bolt/nut combination produces DECREASES linearly as the 'bolt' diameter gets larger. So a single 1/2 inch lug nut at 90 ft-lb produces way, way more clamping force than a knock-off at 90 ft-lb. From there don't forget most cars have 5 lug nuts. The point of the lug nut or knock off is to hold the wheel to the hub. Do you really want to hold you Cobra wheels on with less force than a single lug nut from you daily driver?
