I don't think bracing will net you better understeer/oversteer characteristics.
If you are missing points due to understeer, swapping rear springs or sway would help.
If the front tires are rolling, then a front sway, camber, front springs, or some combination would help increase absolute grip. You can check this using a tire temp gauge.
If you've completely maximized the potential of springs, sways, and shock tuning, move on to bracing.
Awesome. Thank you for your feedback. From the sounds of it, you seem to be quite experienced in suspension tuning.
For me, I am an experienced novice at suspension tuning. So far, I've been lucky in the tuning solutions I've chosen for all my (and a couple buddy's) cars. There are certainly many facets of tuning and for better or worse, we will all take a certain path which we believe is good for us.
Thus far, with the front 2-point and rear torsion beam, the car feels on another level compared to stock. If you lived just a couple thousand miles more west, I'd love to take you for a ride just to experience it for yourself. Also, Danny @TB Performance has suggested I try the trunk brace to achieve the results I'm looking for. His products in my eyes have been great thus far as has his service, so I'll take his word and give it a shot.
For me, I'm seeking to maintain current dampening/spring rates/ride height in this car. If I can even come closer to where I'd like the idea chassis setup to be by just toying with the chassis bracing, then mother***ng bravo;-)
