Breaking parts
Strano springs will lower and are stiffer which will help. Strano hollow 35/22 sways will keep the car more stable.
Other than that if you wish too keep the stock stamped parts consider 1LE replacement bearings/bushings.
LCA's and a stronger torque arm would be the route I go.
As far as other parts, I think you're pretty safe with all of your suspension parts, although it might be worth looking at your torque arm....those are really the only suspension parts that I hear of breaks occurring on occasion. Getting a full length TA with a relocation bracket might be a good idea, and will only improve your launches, but might not be necessary.
I honestly think the only other thing to look at would be your transmission, not saying that it'll go out on you (like the rear), but the chance is always there, especially if you're stalled w/o a cooler.
