Looking for some input and feedback...getting ready to build up my 2012 Roush Stage 1...my thinking is Stage 2 suspension kit, then Roush Supercharger (Phase to be determined) any feedback or suggestions please chime in before I start to get everything together before the build...thanks

 

I have done this already on my 2011 Roush Sport, I had a roush supercharger installed a few years back, love it , I installed a white line panhard bar after lowering with the Eibach springs. I also added a jlt. oil catch can. This year I installed a jlt Big air intake. W/ a brenspeed tune I am up,to about 650 horse I had a small problem after tune and cai, I was getting to much air so jlt sent me a foam type restrict or that goes into stock air intake . Runs great right now, it's in the shop right now getting the a team brake upgrade installed Hope this helps feel free to ask questions

 

I would say compare suspension kits from other manufacturers (Steeda, etc) and go with the one that ticks the most boxes for what YOU want or expect from your car.
I think it is a good idea to do the suspension first, it is easy to add HP to a car that can handle it later on if you are convinced you need more.
