Yea no I get you, while my car seems like it should handle like a beast, i drive like a bad, so no worries, you're preachin to the choir
To be honest, running at the track is pretty hard on your truck, in my opinion track cars take more constant abuse than a single bash sesh.
Also take into consideration the idea that the other vehicles at the track are probably loaded with upgrades to maximize durability and performance so they seem indestructible in comparison.
My stock shock rods were like a wet noodle and once I switched to an aftermarket shaft with a different rod material, I never dealt with another bent shaft.
You may even want to look into dual rate springs, while they're more of a "best of both worlds" solution, they allow for compression in turns while dishing out the strength for jumps
I know my suggestions are very cost based and I apologize, i've simply come to the conclusion that with this hobby throwing money at an upfront cost is a lot easier than bleeding out money here and there as well as dealing with the head ache of your car just not working. Let us know what you come up with, really it's all just trial and error, me running a light oil with a two hole valve for my front shocks may not create the "feel" you're looking for D:
