How (NOT) to install coilovers

He hit's every nut with an air impact... :eyebulge: My lord... DON'T DO THIS!!
especially on the damper nut...

You should NEVER torque anything down with an impact wrench and especially not an air one... the peak torque you get out of one of those is in the thousands of foot-lbs. We've done studies and impact torqued nut torque levels are WILDLY inconsistent.

1000s?

Maybe 100s

Still, I wouldn't use an impact gun very liberally on sensitive components.

I use my huge impact on everything. I took off the panels under the car with it. I just turn the bitch down when I was tightening it up. Air for everything; I am too damn lazy to move my wrist, you kidding me!

1000s? No. I agree on not assembling stuff with an impact and the torque accuracy being non-existant, but even a Thundergun isn't putting down thousands on the tightening side.

You can impact with torque sticks, but I don't bother.

Air ratchet at most for me, I never tighten with an air impact, even with it turned down I've broken too many things in the past.

Whatever works for you though :)

Maybe someone @vividracing can explain why they do this!?

On 1 it barely does anything, I normally have space to spare if I am using a torque wrench. Then again it is a max of 900, if I used my 3000ft lb impact (for working on tractor equipment) I would be afraid.. I have broken quite a few bolts using a hand ratchet. I have an air ratchet but it just seems to puny and cannot remove really anything; my battery impact seems more powerful. It is more about moderation and not tightening something on max torque and holding the trigger. You can do most stuff on the car with air tools.

Thats makes me cringe.

I also hate when people use impacts on lug nuts.

:sigh:

I don't use an air ratchet to remove, just to snug bolts :)

I'm alright with using air to remove but I would have done a lot of those nuts by hand to re-install. Especially the top strut nuts and strut top mount nut. Just my preference.
I used to look at vivid as a two headed demon because their customer service was the worst in the industry. But I have kept quiet and waited to see how they do in the BRZ/FR-S community.
You can't really say that they did it wrong unless you know how the impact torque was set.

dont hate based ona video

you have to know how to use tools, and not be one. I dial my air line down anytime I am tightening a bolt that later needs to be torqued.

impact guns are nice for taking things off, never use it for putting something together

I'll bet that number is an average. You're instantaneous moment could easily be in the thousands. Those specs are more generally for breaking bolts free, because ... you know... you shouldn't be torquing down nuts with an impact wrench. It's like when you hit something with a hammer. The instantaneous force can be QUITE high.
