There've been posts by folks who've pretzeled up the upper torque rod mounting points in the 700 cars, and broken the stock torque rods on the 200 cars - look at them. They're pretty flimsy. If you're gonna launch hard, I'd want to close off the open 'triangle' in the upper mounting sheet metal (look at it, you'll see what I mean), and box the lower control arm and it's chassis mounting point. I added IPD's adjustable upper torque arms - they are MUCH heavier duty than the stockers and come with poly bushings. The biggest challenge for really hard launches is getting enough tire under the back.
