$225 is $10 more than I paid for the single adjust QA1s. Whats the warranty like on the Viking.

I've said it all along, it needed heaps more rebound dampening. Compression adjustment settings will be weaker for those of us with the Steeda bars as the bar stiffens the compression. Having the ability to dial that for those on stock bars is going to be helpful. Not quite 2 birds 1 stone but def would help those without the rear bar.
QA1’s settings are pretty much the same

I ordered a second set of the Vikings so I can send them down to you unless I get them before I leave for Phoenix on Monday then I can bring them with me and we can meet up to get them.

Will Viking make a front strut?

I am certainly going to ask them about this however it might be more like we send in our strut and they retrofit it by installing a shock cartridge in our strut. I really don't know. I'm just trying to get this rear shock thing dialed in in-between all the other things I have going on.

Yep. The focus is the rear suspension. But if there is an opportunity to get a front strut, I am super interested. Anyway, thanks for spending the time on this. So many people will benefit from your efforts.

Yes I would also like to get front struts too but can only work on the rear since it's much easier/cheaper/less time to install for us to figure out if it will work in most scenarios.

Viking warranty is 2 years. They are completely rebuildable and customizable in case you want to have the valving changed. By the way, they are not gas charged shocks which by design will give a better ride.

Mark, sorry for the ignorance, but do you mean gas charged shocks will give a better ride? I think that is what you meant.

No sorry, gas charged shocks give a more sporty ride. They usually have stiffer compression than rebound just by their design and that’s the opposite you want for a smoother ride. The Koni yellow sport’s we are testing has adjustment for rebound only. It wasn’t until we brought it up to full firm (which ends up being about twice as firm as the compression), that the bounce in Anton’s Premium flattened out.

Because the Mach-E has such a high sprung-to-unsprung mass ratio, I think we are going to be looking for a shock that correspondingly has a very high rebound-to-compression ratio. Maybe up to 4:1? A lower compression force than typical might be helpful too. Basically, compression damping controls the unsprung (suspension) mass, and rebound damping controls the sprung (chassis) mass.

Another factor is the rear springs on the Mach-E are very stiff, so they alone are going to resist a lot of compression when hitting a bump. Therefore the shock damping in that direction can be weaker to allow the suspension to move up and absorb the bump. But then after the bump, the powerful springs want to push the wheel down too fast causing bounce. So we want a lot of rebound control to counter those powerful springs and allow the wheel to move back down more slowly.

With the dual adjustable shocks, it would be interesting to try turning compression all the way down and rebound all the way up. That might be a really smooth ride, but there could be traction issues as the wheel might not be touching the ground for a while after a bump.

When they’re finally done retrieving all the data, how do we get this to the Ford engineers who clearly messed up when picking the shocks for our cars?

That part is easy. Just mention @Ford Motor Company and they will look into this for us, because this is not an experience they want us to have.

Maybe something like this?

This is exactly what I've been trying to say and what we've been finding in our testing but I'm not very good at explaining all of this suspension stuff. It's not my area of expertise that's for sure. Thank you Lee, for the detailed explanation. ?

For those that are into suspensions, here's some info on two of the four Viking series shocks I am testing. Viking has 4 series of shocks. Voyager, valved for maximum comfort, Warrior, valved for comfort/sport (the one I am testing right now), Berserker, which can be custom valved for specific applications and Crusader, which is valved strictly for completion/track use. All of these shocks are dual or triple adjustable with a quad adjustment coming soon.
