Tubular K member design

hello
my name is Tim
I am looking for some input from FABO members about my tubular k member design
I have made a couple of prototypes already and tested them in my cars. first k member used the stock lower control arms and torsion bars but went to a front steer rack and pinion for oil pan and header clearance. second frame is a variation of that frame with custom lower arms and coilovers. both frames use the stock spindles and custom steering arms to maintain proper Ackerman angles. What spawned me making my own frame in the first place was 1: I had already spent a bunch of money on brake upgrades 2: cost of all the options in aftetmarket frames on the market and 3: I have installed and worked with a couple of the other frames on the market in customer cars and found design issues.

My question to anyone reading this is what would you like to see in an aftermarket kframe that is not being offered at the moment?

sorry no pics of the frames right now. there is snow on the ground and my cars are in storage. I'll take pics as soon as I have them up on the hoist next. thanks
