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

[Mach1E]

I for one cannot wait for the Lincoln version. I would think it will be based off the Mach-E but I've never been able to find any hard specs on the Lincoln Star yet. While I am sure it will be a better riding car then the Mach-E, I highly doubt it will be an Aviator ride but maybe they can get close if raised up a bit which is entirely possible.

If you want to start going down the path for a better ride, the first thing you want to do is change out those OEM tires. If you are staying with your OEM GTPE wheels, go up one size to 255/45/20 and run a max tire pressure of 36 psi which will keep the load rating Ford recommends for the Mach-E.

For an all season tire my recommendation would be to stick with an ultra high performance all season beings I assumed you bought the GTPE for performance. The least expensive and really good Continental ExtremeContact DWS 06 Plus is an all around great tire. For an EV specific designed UHP All season, there is only one manufacturer at this time that makes one and that is the Pirelli P Zero All Season. I happened to be running those on the front of my car right now and they are probably one of the quietest, smoothest riding UHP A/S tire I have tested so far. Pirelli has two, however, they are extremely expensive and probably because one is designed for the BMW i7 and the other for the Mercedes EQE500.

I can go on and on about changing out to wider wheels or going with summer performance tires and give you my recommendation on those too but that will have to be for another time.

Thanks!

When it’s tire time (which unfortunately may be soon), I’ll probably go with the Michelin Pilot Sport 4S.

Freakin loved those tires on my Chevy SS. Insane traction for a street tire. Might even get a real 0-60 on 3.5 out of them!

They're also my all time favorite max performance summer tire. I have a set for the Mach-E (my summer tires) and they came standard on the GT500 and Focus RS. Besides the P/S Cup 2's, they're probably the grippiest tire out there.

I would like to make a few mod without going too crazy. Addressing the rear suspension is something I'd like to do. Ford's first go at this and their price point is on target with what I expected. If I could afford it I would have purchased a Mercedes, Lucid or even a BMW EV. I don't compare the MME to other cars. I did my research, I knew what I was getting, I loved the design and the price was right.

You can get a BMW i4 for MME Premium money. ?‍

Mark, thanks for mentioning this. Somehow I missed that the P Zero All Season Elect is a low rolling resistance tire. I did some on-line searching and on a Tesla forum, Model 3 drivers have reported improved efficiency over their stock Tesla tires. That is pretty cool.

Apparently there is an Elect version, and a non EV specific version of the P Zero.

Now this tire is at the top of my list for when I need new tires. Which will probably be in the next year or so.

There are many manufactures that list their tires as EV ready but are not actually EV specific tires. There are several manufacturers now that make EV specific tires which have a lower rolling resistance, are quieter and have a smoother ride. Several members here have been using them with positive feedback.

Pirelli is the only manufacturer I know of at this time that make an Ultra High Performance Summer tire and Ultra High Performance All Season tire that are EV specific. Pirelli also make many other P Zero tires that are not. You have to know which ones to choose. They are usually ones designed and made specifically for manufacturers of EV’s like Porsche, BMW and Mercedes. These are the ones I’ve been testing. They aren’t cheap but the are really good. Unfortunately they are only made in specific sizes for those manufactures however some of those sizes do fit the Mach-E GT wheels like the 255/45/20 size.

Another member I’ve been talking to recently just bought new wheels and the same Pirelli P Zero All Season EV tires I’ve recently installed and will be getting them installed next week. Looking forward to his photos and review in this thread: https://www.macheforum.com/site/thr...wheel-and-tire-information-and-pictures.7258/

I’m on a plane to San Diego right now and will be back Monday to continue working on this rear shock project. I have a few more shocks coming in for fitment and Lee is going to help out with some of the testing. I’ll be sending some shocks down to him next week. Lots going on…… Stay tuned. ?

I went with PS4s on my first Mach-e and was extremely unhappy. They have a stiff sidewall for cornering but they made the ride absolutely savage. Like to the point where I thought I might have to take rear seat passengers to the hospital for neck and back injuries. I know a lot of people think the ride can't possibly get worse, but the stock primacies are masking some really poor suspension tuning.

 

[azerik]

I have made some progress. Normally I would never think 'lets take an adjustable shock and turn it's dampening all the way off'. More so as when set to zero I can move it by hand with very little effort. I've been tooling around on 2 clicks of compression in all this testing. The one time I took it down to 1 I didn't realize I had cranked the rebound up to 17 clicks. That was the night I ran out to the airport to pick up my wife. It was on 15 I added 2, that was 1 or 2 too many on the rebound.

When I picked my wife up that night I could feel the shock loading up. Basically getting to a harmonic point where it does pretty much nothing because the bounce up is happening when theres no travel available.

Today I ran that same 7 miles of road. First 1c/14r. It was pretty dang decent but a little firm with too much of the expansion joints being felt through the seat. So I then ran it at 0c/14. And oh wow, we're getting somewhere. Still a little bounce over some stuff but it was a ton better than it had been. So I ran it again at 0c/15r. And it was a different car. Remember I have my sway bar in the rear on the lightest setting. There's very little side to side wobble when going over expansion joints on sweeping over passes. But I can totally live with it. Maybe some day I might bump the bar up one notch but this is really quite good. 0/16 I can try later this or next week but wow. I was nearly giggling.

Now here's the kicker of my findings. They probably line up with what Anton has had the whole time with the Koni's. I was talking to Mark and he confirmed the Koni's are around a 0 or 1c. Which would line right up with where I am. This dual adjustable shock set up running in the range of $450 to $625. If the Koni's ring in really close, they're about a $250 fix without a bunch of other tweaks in the install to get them to work.

Mark said he is going to sent a set of Koni's my way to see how well they match up. I'll be pulling the Vikings off this weekend probably and installing the QA1 duals that I bought, unless the Koni's arrive before I get that far. (If the Koni's work I might be able to send these back to Summit and save myself $300ish.)

And now I'm going to run the 8 miles that I have run some 2500+ times before. "Hell road"

Thanks for the report Erik.?

This post couldn't have come at a better time as I was just about to drop the 3K on the kW Coilovers.

Eagerly awaiting your review of Koni vs Vikings.

 

[azerik]

This still doesn't solve the front end bounce. Which the KW's would as they're adjustable.
I noticed on hell road that it feels out of sync if going under 25 mph. Pretty much any of these concrete sections that create that harmonic bounce. At about 30 they mellow right out but 25 and below there's a rocking motion as the front doesn't compress anywhere near as much as it does at 30+. No matter how good we get the rear the front will continue to add it's input until we make some progress on it.

I think. And havn't found an easy way to prove it yet without having to tear the suspension out or at least drop the rear arm to replace the spring, I think the way all the other rubber bushings for the suspension are like the a-arms. Fixed in the rubber. Meaning if you unbolt the rear arm and pull the spring out, if you lift up on it, it wont swing freely like a urethane bushing arm. There's 9 rubber bushings. I'd be willing to bet one could get a better ride as well by adjusting the angles to which all these bolt together. But some of these are alignment points.
HB 2, 4, 5, 6, 9, 10 look like they could all be adjusted if one could torque them correctly after and if the bushing isn't keyed. (another layer of the onion)

 

[markboris]

The reason I ordered more Koni’s for others to try out is because I’m hopeful they will do 90% of what the dual adjustable’s do and at half the price. Plus they have rubber bushings for the lower support same as the OEM shocks so they will not add any noise like the Viking poly bushings do. I won’t get them in until next week.

My GT is waiting...

 

[Caliboyz001]

@Ford Motor Company really dropped the ball on this one and need to pay you guys for fixing their problem.

 

[Dr Obnxs]

I haven't read all these pages so forgive me if this has been covered. In the restomod world, a lot do QA1 custom adjustables.

https://www.qa1.net/tech-center/tech-articles/how-to-measure-custom-shocks

 

[azerik]

Custom adjustables nearly $500 a shock. But that’s what I used to order the ones I have. TS903’s and TD906’s
Hard pass on an actual custom shock due to cost. But I have 2 pairs of QA1’s now and a set of Vikings which are very very similar to the QA1’s.

I was messing around after running the hell road and dropped the tires another 2 psi. I think they’re now too low as there is a big more low speed bounce over expansion joints and parking lot imperfections.
In other news I might have done a tire test against a newer ICE GT from 20 to 80 and didn’t lose an inch. Can’t say I’m disappointed but I’da liked to lead him instead of looking right over at him the whole time with a smile. LoL I didn’t get the chance to yell ‘Not a real Mustang! Not a GT either! (I shoulda got the GT…)
