UPDATED: Replacing Rear Shocks: Reducing the rear end bounce.

[markboris]

We need to show Koni this thread. Gotta say Mark, well done.

Thanks but there are others that have helped out with this project too. ?

Absolutely! Thank you all and well done!

Sorry, don't mean to annoy anyone by asking, but which suspension produced the most "cushioned" ride. Did anything ride even remotely softer than factory? I've been following over the past 25 pages but I've lost track with which suspension was which. Thanks!

None of them is softer from an impact or compression standpoint. What we have there is what we have due to the lack of suspension travel in the car. My impression of what I have read is that the Vikings are more adjustable, having a larger range of adjustments (and compression as well as rebound) but the Konis at their stiffest rebound setting control the unwanted oscillations just as well for less cost. ??

Message from Koni:

Thank you for contacting us here at KONI NA. Another member of your forum had reached out just last week pertaining to this same post concerning the ride quality issues that many find with the rear of the Mustang Mach-E. Just as it was mentioned to him the Mach-E is in the early decision making phase of the process to see if there is sufficient demand worldwide to justify the development and production costs for this application. However, we here at KONI NA are already actively pushing for the development and have expressed the interest of owners in the US. The KONI Engineering team does have a set of the Ford original equipment shocks for the car for review at our manufacturing factory in Holland, though at this point we cannot say for sure as to whether KONI will or will not be making parts specific for the Mach-E, as there are several variables that going into that decision making process to ensure a viewable business plan on a worldwide scale.

"problem' is Koni is only getting half the picture by looking at the factory shock. It's just a normal shock. They're not getting the other half of the story which is the torsional pressures from the rubber suspension components. The rubber bushings on the rwar are bolted and torqued at ride height. The service manual states several times it must be tightened at ride height. The issue is under load (compressed) those rubber bushings act like additional springs. So the rebound pressure is higher than if it was just a spring. That's what we're accounting (well trying to solve actually) for by choking the rebound as much as possible. It really doesn't need help in the compression side other than for large bumps.

That said the Koni's mellow out the bouncing and flopping around that the backend does over bumps, and it really helps with the harmonic bounce on the freeways at speed because it slows down the back end and absorbs the minimal bumps. The front is still the front, and one can counter act it via tire pressure just like before any of this shock work started. You feel a little more of the road imperfections in order to not feel like you're riding a mechanical bull.

This car can't have a 'plush' ride. It wasn't designed for it. Due to the limitations built by Ford we're simply trying to do the best we can to keep it under control better. I have to say that with the shocks the front is less noticeable in it's bounce. But nothing has changed with the front, you just don't pay attention to it anywhere near as much because the car is no longer a rodeo drive.

Koni really doesn't need to do much to make a set of shocks work for this car. The ones we have already do. We're just looking for a little more tweaks to make it plug n play. Remember these are Koni Sport shocks.

Hey guys. Any updates?

thanks

Yes I’m taking photos of how to configure the Koni’s with part numbers and or descriptions. I don’t do videos but it’s easy to do. Talked to Erik this morning fine tuning a few things. He will take a few photos of actually installing them in the car even though it’s very easy and straightforward. He’s got them in his car along with a few others testing. So far everyone likes them a lot. I was out of town until last night and tomorrow getting my HVBJB replaced so been a bit busy. I’ll be posting this tomorrow night or Sunday.

 

[CAL465]

That's great. Thanks again!

 

[azerik]

I’ll try to get the video done on Monday. It’s cake but a busy weekend.

 

[markboris]

I updated my first post with a parts list and instructions for adapting Koni shocks to the rear of the Mach-E (non PE). #1

 

[CAL465]

Great job on the instructions. They are easy to follow.

That would be fantastic @azerik . I'm not much use at modifying cars but my best friend certainly is. I'm sure he could help me with the Konis. It's been said but I'll say it again, thanks so much to you and @markboris and anyone else involved for taking on this project. Posts like this add real value to being a part of this forum.

Mark thanks again for the instructions and thanks to everyone involved for the excellent work.

I am OCD about keeping my original shocks completely original. With that in mind does anyone have the part number for the black cap on top of the shock mount that we need to modify to fit the Koni's? I have done a long search and have not found anything.

I have all the other parts on order.


EDIT - Mark just informed me that the cap is included with the shock mount I ordered and not separately available - I am happy with that.

Thanks,
Lou
