The front bar keeps the front outside tire from dipping and the rear inside tire from lifting. See if you have an issue with that. For me, I liked the way the car handled in all other aspects of transition, but I finally had enough evidence to fix that performance gap.

Hope your R7s are working well. My A7s really warmed up fast, and the mega-sweepers that were set up almost overheated them in 5 runs (few cars, lots of runs). TireRack says they will last longer than R6/A6, but taking care of them (psi, temp, alignment) is a must.
