Hi, I just bought a 2013 Mustang GT CS Convertible (auto) with a Phase 2 Roush Supercharger. The car runs absolutely flawless, however, I do not feel the stock suspension is built to manage the 640hp. When I step on it, the car lifts up, and almost feels unsteady. There is too much rebound in the shocks when the car comes down, which adds to the unsteadiness...if that makes sense.

I would like to upgrade my suspension to keep the car flat under power, as well as to improve the handling, as the car is sloppy compared to my Audi S4. I wont be racing the car, as I bought it to drive around in with my wife and kids. Looking for your suspension upgrades advice.

Cheers,

A good set of springs will likely be what you need to form it up. It would probably be a good idea to upgrade your control arms as well. BMR makes great stuff and would be the route I'd go if you do change springs and lower the dark you'll also need an adjustable panhard bar to realign the rear end.

Congrats and welcome. I'm a big fan of BMR gear too, its well built and solid stuff.
