it makes me think with all this work you're able to do why you wouldn't go for a RWD conversion.
im not sure if this is a way for you to "do it cuz you can" or "do it cuz it's unique." im not sure what the total cost of this project is, but im guessing with the money you're spending you might have been able to get a vehilce that is already an AWD
but if you truly want different drivability while still making it a DD, i would rather it be just RWD. that way you get better performance than a FWD, but also other perks like less WHP loss than an AWD, less strain on the front tires from wear, and a much more even weight distribution
overall i do think this is a very cool project, and i really wish i had the welding and machining ability (along with the tools) that you have to do things like this
