One of the key pcs to my front suspension is the use of the C6 Corvette upright.. So I sat down & did a cost analysis of what all the components were going to cost me to buy & machine.. not cheap.. So we are making our own upright.. steering arm will be built into it, dual taper serviceable hub bearings, our own hub, & provisions for rotor ducting.. Currently my engineer is working doing a FEA & analysis.. Then my machinist will look @ the design for cost & optimization..
