I dunno how much I would trust any of those, because decades of R&D has gone into those and even well established companies don't manufacture their own but get them from companies like Bosch, Siemens and Takata also because its not financially sensible to invest so much money into manufacture of these complex products and systems.
As for suspension what kind of setup do you have? Macpherson struts, wishbone or leaf springs (hope not)
And yeah work on that prototype drive it on for at least a 100k kms on Pakistani roads in all weather situations from the heat of sindh to freezing temps in KPK. You'll learn a lot about the car. Its strong points and most important of all its weak points and parts wear rates and stress areas which might need redesign or reinforcement. Running 3d model simulations is one thing, real world testing is another
I've worked on a lot of prototype testing for a lot of manufacturers including but not limited to Porsche, Land Rover, Jeep, Nissan, Toyota etc etc
