Have you tried *not* using the turret mode?
It points where the vehicle does and will even auto-acquire targets in your FOV.
Yep, yep, yep...
Set up VA to control the throttle and change/lock targets.
I use a CP-48 Keyboard to control direction but you can remap the the joystick YAW axis to do that.
Scout the path first.
Pull up close to the perimeter.
Set direction to REVERSE.
Crank in about 3-4 engine power
I set pips 3.5 shields, .5 engines, everything else to weapons.
I can usually waste 2 of them before they even start to return fire.
Release the brake and back away.
If shields start to get thin or weapons get low, increase speed.
Usually someplace around 1.5K they stop chasing you.
Let everything recharge and start a slow (2) advance and lock and shoot as they become visible. If you are using top grade ammo and moving slow so the auto tracking can stay on target, you can do them damage at ranges (200 m) where your shields can take everything they shoot.
