Reconstructing GT Rear after crash - need some help please

[Locodionho]

Hey guys
On saturday I finally bought my first Mustang, a 2016 GT Premium, and on sunday I turned arround on the highway and crashed into the middle wall (old semi slicks and the beautiful but very rainy mexican jungle aren´t a good combo). Luckily and however this was possible I just crashed the tail; rear bumper and tail lights.

The car had a GT350 Rear Bumper which I had to leave completly over there, just took the cable tree with me (and the Tail Pipe Inserts, the only piece that wasn´t necesary )

I want to reconstruct the same tail with some modifications in the lightning.
As far as I found out until now I have 3 options to get the GT350 rear on my GT:

1. Get a solution like the MP Concepts GT350 Style Rear Bumper from americanmuscle. But reviews are really mixed and I read a lot that it doesn´t have same quality and look like oem.

2. Get a (maybe used) GT Premium Rear Bumper and a 2015-20 Shelby GT350 Rear Bumper Valance, OEM from Ford performance Ford FR3Z-17F828-AB, or GT350 Style from eBay.
THIS should be a premium, right?

3. Not sure about this option, to get a complete OEM Shelby GT350 Rear Bumper Cover with Valance, does it fit on the S550 GT?

Then, as I left everything over there, I would need:
Rear third break light, Side marker lights, Diffusor Lights/Reflector, Parking Sensor 4x (at least I saved the cable tree), Rear trunk switch, License plate lights 2x. Anything I forgot?

And for the instalation I would need a pair of Rear Bumper Reinforcement RH/LH and the Rear Bumper Isolator, right? Anything else?
At the rear bumper isolator, is there any difference in between w/ and w/o parking sensor? Or is it the same piece?

Already a big thanks in advance!

From what I can see you didn't hit dead on the center, rather she took a good blow on the right and then bounced around and hit also the left side (I see a broken taillight there).

The exhaust is also bent.

I guess you need more components than the one you listed and for sure a shop that can cut and weld a new panel on to the right back side because you're gone far from just being lightly rear ended.
Probably also check the geometry on the rear....

From what I see you are going to pay a little more than you expect for this mistake.

It happens to anyone, just fix it properly.

Luca1290 is right, you may have hidden damage. When I was much (much) younger, I lost it on an off ramp and had a glancing blow across the front of my car. It wasn't a hard hit and cosmetically, less damage than you have, but the subframe was tweaked messing up the front end geometry. The good news was that the car was repaired and was fine.

Trunk gap is closed up on the lt side too. Rear needs to be checked for being out of square. Rear body panel is done. Lower qter needs work and very likely there is floor damage in that area too. Like mentioned, good bit more than just bumper and lights here.

Dry the qters off and look for any buckles. Check the trunk opening and trough too. Everything is welded back there. If one moves, those around it have to as well.

So you were on "slicks" (drag tires) or were you on old worn out tires? In either instance, and unfortunately you found out that neither is a good mix with rain...

Also as others had mentioned, you have more than cosmetic damages there - it is very visible in the pics.

You can try to gather up the parts - eBay, forum classifieds, social media classifieds or LKQ - you can source decent used parts for fair pricing.

That's not the issue - you're going to have a hard time with alignment of the new parts due to the damaged areas. That trunk lid isn't going to open/close as it used to because it's going to cause issues with the driver side 1/4 panel area where the gap is already "closed". The only way to fix that is throwing the car on a body alignment rack, it's not going to be a "tweak" with the trunk lid.

As others mentioned too, there is definitely unforeseen damages, especially under the car. If your exhaust looks like that currently, most likely that exhaust jammed forward when it made impact at speed and who knows what else is damaged under the car forward of the rear.

You're going to need more help than a DIY piece it together. My guess would also be the rear IRS subframe shifted too.

 

[luca1290]

Trunk gap is closed up on the lt side too.

Wow, didn't see that. The whole rear is shifted left.
This is going to cost some real money. Also find some very good shop otherwise your car will never be like it was. This is a job for a professional.

I'm curious about the speed / force of impact, and the general dynamics of the accident.
Also, in the two photographs, the left exhaust is in two different places... and a weird position for a side impact, probably she scraped her underside before resting on some wall.

Good morning!
First thanks for all your fast replies! And please don´t worry, it´s absolutely not my intention to DIY quick-fix this cosmetically and done.
I already have an appointment in a body shop here for today to check exactly this, unseen damages, deformations of the chassis etc., will have you updated then.
Just as I´m living in mexico, you barely won´t find any parts here, almost everything is imported from the states and shipping is crazy (shipping just for the bumper cover is over 500USD), so I´m already trying to find and collect all parts needed to get them collected and later on shipped by a freight forward company. The work will be done profesionally and absolutely everything necesary in a good body shop, will get the car to merida 4 hours from here to get it done properly.


There was no hit with the left side or any other part of the car. The tail lights are broken due to the hard tear-off of the bumper, they´re broken on both sides, on the right side you can see it better.
The exhaust, I hope it´s just deformated, because the bumper just broke left to the tail pipe inserts, and then got ragged to the right. I don´t think it jammed forward, looks quite good from below but we will see later on the lifting ramp.

The trunk opens and closes fine, but yeah is definately shifted left and has a closed gap.



To the speed/dynamics of the accident:
I went straightforward with about 80km/h (50mph) on a plain straight track, when suddenly felt that the rear went out of control, did a turn arround with the rear to my right, scratched slightly with the front at the middle wall then stopped by crashing with the outer rear to the wall. I first though okay the whole side is completly done, luckily not a single contact or scratch neither with the side or the rin.

I will attach you some more detailed pictures I just took. It´s definitely as you´ve already seen the Rear body panel, lower quarter and we´ll see soon what more :/

So you were on "slicks" (drag tires) or were you on old worn out tires? In either instance, and unfortunately you found out that neither is a good mix with rain...

Bought the car on saturday with semi slicks on the rear, already ordered new pirelli p0 cause I don´t see any sense having the slicks on mexican streets with the rainy weather here, but they´re gonna arrive in about 1 week, and yeah, obviously wanted to take a ride with the car the next day.
It´s not my first "fast" car, had a 350z, 370z and a corvette c6 before, drove absolutely carefully and slow for the circumstances, but yeah honestly I´ve 0 experience with (semi-)slicks and that´s what broke my neck... Well, now I know :(

is it just a picture or you have different rear tires left and right? BTW, Federal 595RS-RR are not slicks in any way, these are 200TW extreme performance tires, somewhat popular for track days. at least the one on the right side is this tire. From Federal website: Flame-shaped grooves contribute to decreased aquaplaning and improved traction in rainy conditions. your fronts are nowhere close to 200TW are those Pirelli's PZ4 or Yokos Advan Sports? it seems that the previous owner was using whatever he could find in his garage or a junkyard. there might be more stuff going on with this car that you might want to check.

 

[luca1290]

The damage does not look too bad, probably there is some cutting and welding to do.
A thorough disassembly of the upholstery of the boot and some measurements on the frame machine will tell how much damage there is.

I still can't wrap my head around the bent exhaust muffler, how it came in that position.

it seems that the previous owner was using whatever he could find in his garage or a junkyard. there might be more stuff going on with this car that you might want to check.

If the car has different left/right or front/rear tires it means she's been run on a budget and you might want to check everything else.
Did you put the VIN through Carfax and googled it?

 

[ORRadtech]

Well, it likely wouldn't be totaled here. But, a good US body shop is going to charge between $12k to $15k if I had to guess.

 

[Locodionho]

Tires are pair-wise the same, front regular 255/40ZR19, back the Federal 595RS-RR, this has been openly communicated from the beginning on and i knew I had to buy 4 new tires.


Ok so back from the body shop, on the first view:
Beside of what we already saw/know, found some more details, painting on the left quarter panel is broken just on the edge, front bumper has not just scratches but paint is broken on some points, plastic of the right fog light is broken, lip has some scratches.
Exhaust muffler is bent. Floor looks good (on a superficial view).
They want to fix the rear body panel and lower quareter, I´m more for a replacement!?
Now the worst part:
The trunke has a closed gap on the upper left, but on the lower right.
Right tire stands out a good cm (0.4 inches?), left tire not or even stands in a bit. So the whole rear/chassis is bent to the left. On friday they gonna get it on the ramp and all measured. FML :(


Anyways, could someone be so kind and reply to my initial questions about the parts, as I´m gonna need them anyways and want to get all together asap, collection and shipping to mexico takes also a while.
The rear bumper reinforcement looks good on both sides. So for the installing it should only be the right bracket and the isolator whats missing?

And could someone help me out with the correct description of this part? I though its the rear bumper bracket passenger side. Is this one correct?

 

[luca1290]

It should be the same part, but I think it's better if you wait someone that has access to the parts diagram.

Oh thanks a lot, didn´t knew the site, helps me a lot to double check the parts before ordering!

Thanks for your words man, was kinda down this wee, haven´t had any accident in 13 years of driving and then this at the very first day. First of all I´m happy that nothing worse happened to us, the money hurts yeah but goes over, what hurts more is that the car was in a really good condition and I know it won´t be like this again, but however, almost got all parts together, next week gonna get them shipped over, and then I hope they gonna get it fixed as good as possible

 

[luca1290]

[...] and I know it won´t be like this again [...]

That's not said. I saw cars completely rebuilt and if you fix properly all that there is to fix they can be restored to brand new. It must be done by a real professional though, and those are quite hard to find.

A neighbor of mine has a 64 Porsche and a VW Bettle and both of them were restored to pristine conditions. The fit and finish on the paint, the panel gaps and all the details are better than any new Kia or other shitbox.

It depends how much you care for the car and how much time and money you are willing to spend, but yes, it can be brought back to what it was before. Cars are not disposable objects.

Good luck!

 

[Locodionho]

Okay, got almost everything together now, but I´m stuck at the very last parts.

Maybe someone can help me here please.

I need all the 4 rubbers (is brushing the correct description?) right side new as they all broke with the collission. When I search for rear control arm brushings, I almost don´t find anythign and the brushings seems to be more expensive then the whole new part, can this be?
If it´s cheaper to buy the whole parts new, what do I need to replace all the brushings? Rear Lower control arm, Rear upper control arm, Rear Lower Forward Control Arm, something more?

And the other thing, found the rear body panel and the rear bumper crash impact bar.
But whats missing is the side piece, I searched for lower quarter, inner quarter, rear outer panel, but couldn´t find it, has someone the correct description or part number for me?

And the last one, breaking pads. As I already found out, rear braking pads are all the same. Front are different between regular (4 pistons) and performance pack (6 pistons). Afaik I´ve got a GT Premium without performance pack, but I do have clearly seeale the big brembo brake on the front. So which breaking pads do I need for the front? Will these fit?
