Car drifting at high speed after shocks replaced, Why?

This is a subjective question of course, but how much damage serious or minor if any has been inflicted on the car for the last 2 weeks? Of course Monday Im going to have it aligned.
But what has been happening to the car all this time?

Thanks!
My Key, how many miles did you put on the vehicle to cause that kind of damage?

Lets be frank here, he only replaced the rear shocks, you can blame the alignment, but if you weren't changing the ride height significantly with a spring, and were installing oem shocks, you do NOT need an alignment, that is absurd.
I'd be focusing on whether they mounted the shock properly, whether they didn't kill the lower shock bushings when you were mounting it, and if the shocks were actually faulty.
Since the G35 do not have a floating rear end, rear instability is usually caused by a bad shock, bad suspension link, or bad bushings in the rear.
Ride height changes impact the alignment in two ways, if you lower, they add negative camber and positive toe, all good things for stability, better cornering grip and better tram lining(to a certain extent ofcourse, and it'll eat tires(mainly from the toe)). The reverse happens when you raise the vehicle.

As for why for work on the rear: it's because the rear is adjustable on the cars and they always require a "4 wheel alignment." It's not like a truck or car with a solid rear axle on leaf springs where the rear has no alignment adaptability.

The problem with recommending an alignment to people all the time as a solution to every possible suspension issue is that on most older cars, especially the ones with a multi-link suspension, usually have other components that are worn out or need servicing.
Now I am not saying that an alignment may not fix your problem, it very well maybe the culprit, but likely than not it could be something else.
No components are touched during the front strut/spring removal, You literally unbolt the 3 bolts on top of the strut and the 2 bolts at the bottom, and 2 bolts that hold the brake line in.
The rear is the same. The strut just unbolts, 2 bolts top, 1 bolt bottom. Spring cup is its own bolt.
That being said, none of the bolts that are touched during a strut/spring replacement are alignment adjusting.
On the rear suspension that is done by the camber arms and lower control arms.
I've included some diagnosis sheets from the G35 service manual.

^^ This! Any time a part of the suspension is replaced (or even unbolted from each other) the alignment needs to be checked.
