I bought the rear traction brace and it worked. I bought the gusset brace and it worked. I bought the crossmember , but despite making my ST body not flex anymore during cornering which feels great, the steering wheel is now sloppy when centered making it hard to keep the car going straight, it takes more angle to turn the car, therefore the steering wheel feels disconnected from the front wheels and isn't precise anymore, and the front wheels have clearly less traction. I did an alignment, I have new indy 500 tires, adjustable sway bar but that crossmember brace isn't it for me.
