And? They've never been a metal ball in a rubber socket. Ever.

I'm not really sure why you want to get into a pissing match over tie rods, but I don't care for it, this is supposed to be fun. My suspension is sorted out already and I only commented here to help out the OP (and did). Do whatever you want to your car, I don't care. No one (except you) said anything about a metal ball in a rubber socket. If you open your eyes and look at the picture I posted of the standard tie rod you will see a rubber bushing on the end that attaches to the rack. Then if you move your eyes about a half an inch down the screen and look at the turbo tie rod you can see that the rubber bushing has been replaced with a spherical metal joint. This is the whole reason people retrofit turbo tie rods to their cars. This has been a popular modification for decades. It is nothing new. It is not complicated. Deflection in suspension/steering system is not desired in a high performance environment. Less rubber equals less deflection. If you are unable to see or understand this I can't help you.

If you do any sort of performance driving, then yes, this a great upgrade with noticeable improvements. I've seen several cars up on a four post lift where someone on the inside turns the wheel and you can see the rack move a little bit before the wheel moves due to the slack/inherit qualities of the rubber bushings on the original type.

These pics show that the tie rod has been replaced once before at least (grease zert). But there is a special tool to install the OE ones to make sure the kinematics are correct regarding the fork connection at the rack. Usually leaves less than smooth steering to just install them back in almost always the wrong orientation. This is why some people notice a big difference and some don’t when going to the turbo type.

I thought the TTR made a big improvement on my car. I will say my old tie rods were tired and with the weight reduction in front and wider tires I'm pretty happy.
