Although not required, you would greatly benefit, especially being lowered.
A set of the TCA032 Lower control arms and our CAB005 set to the middle hole will correct the geometry of your arm's from lowering and help to better plant the tires.
Shoot me a PM for a discount code :)
Depends on how much you are lowered.
0 -> -2 is typically where we like to see people sit.
but if you don't have a vibration at higher speeds (60+) then I wouldn't worry about it.
If you're just installing it then set to stock length, and adjust from there.
You'll get some slight NVH depending on the Motor Mounts you use ETC while swapping, but speaking from personal experience on my 2013 GT, there are no other negatives.
Glad you're happy Chris!
I did my RLB at the same time as my LCA and I agree it makes a whole world of difference when the two are combined!
Ever need anything else just shoot me a message!
^This track times speak volumes more than dyno numbers ever will.
Wanna see where the car is, take it to the strip and see the times, how she launches and the MPH.
;)
If on a Mustang dyno that seems about right to me.
On a dynojet back when I was bolt-ons I made
