I'll throw up real world experience and wisdom. If it sticks to someone, then they've benefited.
1) Shop labor will vary by geography and economy. In Central TX, we're at $160-190/hr right now. Smaller shops with less overhead can and do charge less, but this is the real-world range for a quality shop that does Euros and has the proper tools and training to work on them.
2) Even it it's low at $130/hr in your area, the book time for struts and springs on our cars is around 4.5-6hrs, depending on the method employed.
That's 6 x 130 + the cost of a proper 4-wheel alignment after ($100 minimum in most areas for a Euro). You're already at $880 on labor alone. And this is IF you find a shop foolish enough to accept a customer's Chinese e-bay parts.
3) All Coilovers will require at least 1 height adjustment. You're essentially "guessing" the first time you put them on.
You take your before measurements of the car at all 4 corners with a metric tape measurer, write them down.
Re-take measurements after the coiler install, including some time to roll the car around and let the new springs "settle" to their initial position. Write those down.
If the car is drivable, it'll need some miles on it for the coils to fully compress to their final resting height. Take measurements again.
4) If there are any "close" clearance issues between the tire(s) and fender; if the roads are extra crappy where you live; if you and your passengers are frequent eaters at Whataburger and weigh over 220lbs each...all of this will factor into the need to make a height adjustment of the Coilovers.
Now you're beginning to see why labor is what it is. You're not working on a mid-90s Honda Civic or Chevy truck where a strut can be removed in under 20 minutes. And you have to pay for quality work with a warranty,
5) Now back to what everyone else is telling you:
Raceland Coilovers and their competing Chinese lines have almost zero quality control or testing behind their products.
They are not DOT approved for use on public roads. This is all clearly stated in your half English, half Chinese instructions they provided you.
I have repaired and replaced MANY failed components on their kits before. I always tell customers the same: start saving for an actual quality suspension kit, because this one is going to continue giving you headaches.
6) What is your rationale for buying the 034 strut mounts? Have you researched these at all? Did someone convince you to purchase them?
I ask #6 because these have a well-documented reputation, going back 4-5 years, of customers complaining about clunks, noises, harshness etc after installing these mounts.
Most owners with these mounts removed them to go back with stock components, which do an exceptional job at keeping the strut and tires where they belong, without kidney punching the driver and occupants like a Mike Tyson comeback fight.
Let me know if any of this helps clarify.
