The front kickup will make the car slightly more aggressive, this was something i played alot with when i ran Corally. Depending on the track, surface, and grip level, this can put the car on-point, or throw it way off of pace. I would get rid of the kickup to start, they make the block spacers that go underneath the blocks, also you didnt specify, is this car a regular rdx, an rdx PHI, or an rdx PHI '09.
