2012 Nissan Maxima with ESR SR01

I'm running Tru Hart Street Plus Coilovers (lowered 2.75 inches) with ESR SR01 18x10.5 with Toyo Prox ES tires. The ride is great. A bit of tire rub from rear fenders when I'm going 65+mph over large dips but nothing major. I would lower more but I have full 2.5" exhaust piping from the cat back so that right there already has my center of gravity lower throughout the middle section. It is difficult to make it over speed bumps as it is so I'm as low as I'm willing to go for the moment.
