MODS - SUSPENSION / CHASSIS
Replaced the splined bolts that attach the front struts to the wheel knuckles with regular bolts (and painted them black). This gives a bit of play when tightening the bolts to add a bit more negative camber. Replaced OEM front and rear sway bars with Steeda adjustable bars. Have them set on the max setting. Replaced OEM springs with H&R sport springs which lowered the car 3/4".
MODS - WHEELS / TIRES / BRAKES
Changed out the OEM wheels and tires with Signature Precision Series SV706 in gloss black. I have a staggered setup of 20"x9" ET33 up front and 20"x10.5" ET47 in the rear. Tires are Michelin Pilot Sport 4 NO Acoustic 275/40/20 front, 315/35/20 rear. About the weight on the new setup, I saved a total of 12 lbs. The Signature wheels are about 8 lbs. less each than the OEM wheels however the tires are quite a bit wider and slightly heavier. Painted the light gray area on the hat of the rotors plus the rear dust shield satin black so would look better behind the open designed black wheels.

Edit: Aug 4, 2022 changed out my wheels for a new set. Same Signature SV706 in gloss black but with a polished aluminum face (they call it diamond cut) and they are a medium concave this time. Same wheel sizes and just used the Michelin tires from the previous wheels on the new ones.
MODS - EXTERIOR
Removed the Mach-E badges on the doors. Tinted all the reflectors, with 20% film. Replaced rear license plate with a Reviver electronic license plate. Drilled two 2" access holes (then capped them) above the LVB positive and negative connections in the frunk. Eliminated the Pedestrian Audio Alert sound and back up beeping by replacing the speaker with a resistor. Added front and rear mud flaps. Applied gloss black vinyl wrap to upper area of rear tail light sections and liftgate. Tinted upper sections of tail lights. Replaced the liftgate GT emblem with a custom painted Ford Oval in Iconic Silver and gloss black. All exterior paint treated with Ceramic Pro 9H ceramic coating.
MODS - INTERIOR
Tinted front driver and passenger windows with 30% film to closely match the OEM rear tinted windows (it is a little lighter). Completely sound deadened the interior with both Dynamat and Dynaliner in the doors, cargo area and rear quarter panels. Added blue ambient lighting in the rear door storage area to match the lighting in the front doors. I only use the blue color for my ambient lighting so installed blue LED's in the rear door storage area. Had Exclusive Steering custom make a steering wheel in black leather with performance gray Alcantara on the upper part and lower trim section and silver stitching to match the rest of the interior. Had the center section of the console armrest covered in performance gray Alcantara. Removed the warning stickers on the visors. Added a sunshade for the glass roof from Tesmanian. Covered the carpeted cargo quarter panels with CanvasBack protection and have their fold out rear bumper protector. Covered the rear seat backs and cargo floor with AOSK's protectors. Replaced OEM floor mats with Lloyd black Lux mats. Added wireless car charger under armrest. Replaced the Max Defrost button on the headlamp switch panel with a liftgate button from and Explorer switch panel and wired it to open/close the liftgate. Changed the dedicated Parking button to activate the cameras. Added AOSK's sport pedal covers and dead pedal cover. Installed Ice Blue EL accent lighting on all four door panels and dash. Replaced front driver and passenger GT kick panels with Mustang ones.
MODS - IN-CAR ELECTRONICS
Replaced OEM sub with a JL Audio 400 watt powered sub and installed it in the lower cargo area under the floor. Added a remote volume control for the sub at the front of the console.
MODS - SOFTWARE / TUNE / PROGRAMMER
Disabled double honk when car is on and you get out with the key fob or phone in your pocket.
HISTORY, STORY, EXPERIENCE, COMMENTS
Several of the mods I listed above I first did on my Mach-E Premium and took quite a few photos. When I did the same mods on this car I didn't take many photos at all since they would be just the same. You can see more photos on my Mach-E Premium Showcase https://www.macheforum.com/site/showcase/marks-mach-e-premium-4x.63/

Love the wheel and tire setup. Can you tell me what offset you used?

Hey, so there is a lot of stuff going on here with tires. I probably have had 5 different sets on the car (I have an addiction of testing out tires). To answer your question, my front offset is +34 and rear is +47.

The current tires on the car are Michelin Pilot Sport 4 NO Acoustic 275/40/20 front and 315/35/20 rear. I had to modify both the inner finder liner in the rear and the rear upper shock mount to make those 315's fit while still keeping them from poking out more than 1/4" or so. I would NOT recommend those size tires unless you want to make these modifications.

Some of the photos I have in this showcase are of Pirelli Scorpion All Season Plus 265/45/20 front and 295/40/20 rear and some are Michelin Latitude Sport 3 255/45/20 front and 285/40/20 rear. All are on the same wheels, 20x9 front and 20x10.5 rear. By the way, I am having the front of those Signature SV706 wheels machined so they have a bit more style. Should have it done in about a month and will post more photos.

Thank you for the detailed response. I'm interested in a square setup with 275/40 R20's; it sounds like you're saying that will probably work with a 9" ~+34 offset wheel? No tweeks up front?

You are right. That would work just fine. +34 or anything close to that. No tweaks front or rear.

Hi Conrad,
I have a thread on how to add a lift gate switch here:
https://www.macheforum.com/site/threads/adding-an-inside-liftgate-power-switch.6560/
This is where I added a little momentary push button switch under the console area. It is the cheaper and easier way to go. I did this mod in my Premium.

In this link below I went one step further when I got my GT. I replaced the max defrost switch with a lift gate switch and ran the wire from the BCM to that switch.

Several other members in my thread added this mod and it has worked really well for everyone.

Love all the mods! Dumb question - any trick to get the pedals on? Seems the break pedal needs the existing cover removed and the accelerator just goes over. Seem really tight - any trick other than some elbow grease? Thanks!

Hi, you are correct in that you need to remove the OEM brake pedal cover before installing the new one however the new gas pedal cover goes over the existing pedal. They are very tight and yes you definitely need some elbow grease. This is something that is difficult to explain exactly how to install but I just remember starting at one end and really pushing it on as tight as I could on the pedal then worked my way over to the other side. I know that's not much help and hope you get them on without too much fuss.

Thanks so much! Will put some more effort. I see what you mean about doing bit by bit.

Hi Mark. Do you have a thread that illustrates the rear shock mount mods needed to run your Signature wheels?

You don't need to alter the rear upper shock mounts to run the wheels but you do if your are going to run super wide tires.

If you run rear wheels that are 20"x10" ET47 with 295/40/20 tires, that would be the widest you can go with the least amount of poke (they are flush) and no need to alter the rear upper mount. However if you push it like I've done recently to 20"x10.5" ET 45 with 315/35/20 tires, then you do need to alter that mount.

What I did was shave off about 3/16" inch off the back of the mount and 1/8" off the front so the mount sits back about 1/4" giving me the space I needed. It is still really close and depending on the tires you get, some sidewalls protrude out more than others.

I hope I answered your question and let me know if you have any others. I did not specially show what I have done to the rear upper mounts but I have stated a few times that this is what I did. If you want some photos I can get some in a couple of days as I am taking the rear shocks off to test some new ones.

Thanks Mark. I'd love to see some pictures at your convenience. I'm getting very low on tread and am seriously considering wider wheels- and if I'm going wider, might as well go wide!

What are you planning for new shocks? Is this for your GTPE?

I personally would NOT go to 315/35/20 in the rear. If it is just you driving the car, never transporting people or cargo in the rear then maybe ok but under heavy loads, the rear wheel well moulding will contact the tire sidewall slightly. 295/45/20 is the widest I would go. That is what I am running right now on my all seasons for the winter and probably just going to keep these on all year. My Premium that I sold to my friend in Arizona has the same size tires but on the 10" wide wheel. So my personal opinion is go with 20x10" 45ET 295/40/20 tires. Should not have any issues at all. 295's are plenty wide enough.

Forgot to comment on the shocks. I am trying to find shocks that will reduce the bounce that the car has. The GTPE having the magneride suspension is much better but still not perfect. Overall the shocks are way to soft for me. If I can find a decent set I would replace my magnerides for something else. I am going to test them on my car first then others that have the bounce. I don't have any bounce on the roads I have around here. I want different shocks for something more firm. Others want them for less bounce.

Fat Mach, while this is not a photo of the rear shock top support on my car that I altered, I figured this would be easier to show you what I did using red marked areas on new ones so you can see what I took off..

The top part of this mount is the front which would touch the inner sidewall of the tire. That red area I grounded down and gained 1/8".

IMG_4521.jpeg


The red area below I removed which was about 3/16" at the back of the support which allows it to mount closer to the body. Overall I gained about 5/16". Was enough for the 315/35's not to scrape against. They were still really close.

Thanks for following up! I have to deal with enough tire rubbing on my widebody Shelby to know I don't want to add another vehicle to that drama. My tire of choice on the Shelby is the Michelin Pilot Sport 4S. When I tried to price them at Tire Rack for the MME in the sizes you recommended, I found they don't make a 295 40 20.

https://www.tirerack.com/tires/tire...PS4SXLAC&vehicleSearch=false&fromCompare1=yes

Is there a F/R size they do offer that you'd recommend I go with? Maybe 275/295 with a 35 aspect ratio? Or would you recommend finding another brand in the sizes you originally recommended? Although it apparently has snowed twice in the past 2 days here, it hasn't done that since 1976 so I'm not too worried about running a summer high performance tire in my climate year round.

Hey, I'm in the same area you are in (NorCal) so yeah it snowed here too. I also run the Michelin Pilot Sport 4s's on my Shelby so I know that tire very well and also know that it is about the best tire I've ever had. You really cannot fault that tire for its performance. Beings I do live in Sonora where it does snow at least twice a year but more than that, the temps in the winter are between 28-45 typically, I need to run all season tires since the Mach-E is my DD. Not going to drive the GT500 around on those PS4s's in the winter.

I would recommend 265/45/20 front, 295/40/20 rear which are 3/4" taller than OEM and get the Michelin Pilot Sport 4 SUV. It is the closest you can get to the PS4s's we have and almost an identical tread pattern. The only difference is it has a slightly stronger sidewall for SUV's. I'm sure you would be very happy with them. If you want to go one size smaller, 255/45/20 front, 285/40/20 rear, 5/16" taller than OEM, the Michelin Latitude Sport 3's are a SUV/truck Summer only tire. They don't have quite the performance that the PS 4 SUV's have but close. If you want the shorter sidewall look and over all 3/4" shorter tire than OEM, then 255/40/20 front, 295/35/20 rear can get you the Michelin Pilot Sport 4s. Thing is, on the Mach-E, I prefer to not go any shorter on the sidewall or height than OEM for two reasons. One, the car is heavy and short sidewalls give a hard ride and can damage the wheels easily going over potholes with a heavy car. Two, the wheel gap increases which looks like crap in my view. So I always stick with one of the first two sizes I recommended.

Thanks Mark! You make some great points. I'll look at the SUV's.

I only got the little bit two nights in a row. I'm probably only 20 miles from the ocean. I PM'd Terrance but no reply. @50 Deep

That was before Ford added a soft touch camera button on the home screen of the main display. I have since put it back to stock. Here is my thread on how to add a hard button to turn on the cameras when parking. #1
