Tubular K member design

the Ackerman and bump steer issues can be fixed with a propper steering arm design. the very first version I made for my car I swapped the stock arms side to side to make it front steer. the bums steer was fine with this setup but the Ackerman was out to lunch and it had the turning radius of a Mack truck because the arms were too long. I realize that strength cannot be sacrificed in the name of weight savings and I'm not as concerned about weight as I am with strength, geometry and oil pan/ header clearance. I'm not 100% sure but I think the qa1 frame is mild steel I can't find any info saying it is chromoly. if it was chromoly I think the price tag would be a little higher. I'm not making a QA1 knock off. I have made a front steer version that still uses factoy spindles.
