3300-3400ish lbs, 53/47 weight distribution, not too bad. An aluminum block 4.6/manual trans MN12 without too much frills is ~ 3600lbs and ~57/43. The front shock does appear longer though, and that dinky little spring bothers me(as it does on the SC300/Supra) but I definitely like it, being those are actually meant for the heavy end of a front engined car

The rear shock is good but I wouldn’t have bothered with springs, SC/Sports are as stiff as you’ll ever need back there in any scenario

What's you all's view on strut masters front shock coilovers for the mark Vlll?
they’re not “coilovers” in the sense we’ve been discussing, they’re basically a stock Tbird shock/spring assembly to replace the shock/airbag assembly. They use bottom of the barrel replacement parts

So I had an idea pop into my head in the wake of the promising 350Z retrofit, what really makes them work are those standoffs between the shock body and lower mount, if you fit a custom U shaped piece of steel under it as Mike did via welding or the possibility of a nut/bolt solution I have in mind another shock with that kind of standoff could work, regardless of whatever lower mount is underneath it, right? Well Check these out....


04-08 F150 w/4WD. Check out the dimensional specs compared to MN12 :),


Wouldn't think they'd be that close from a 4WD full size truck!

Better yet that rod machining looks like a much closer fit to the MN12 upper mount than the 350z shocks, and the lower perch placement might even be favorable to using MN12 springs. I'm not sure what the performance would be like but being its much a heavier vehicle than an MN12, and a quick google search suggests the spring rates for F150s are in the 500lb/in range, I'd expect these to be pretty stiff from ANY brand in our chassis, and they're cheap too - Motorcrafts on Rockauto are $58 each! Bilstein B6s are only $102 each!(though they're out of stock on a lot of sites).

Food for thought.

The lower shaft is key for it possibly working with us so it is what it is, that’s where I suspect OEM spec might be better than something like the stiffer Bilstein 5100 though? The ride height adjustment is presumably useless to us as I suspect those extra snap ring grooves are meant to raise the vehicle lol, but I do like the loose perch mounting system on the 5100, there might be the possibility of cutting the welds off a MN12 shock to free it from the tube and slip it right onto the F150 one depending on tube diameters

I seem to recall Paul doing something like that a while back...

Yep, here's his thread.
That’s not exactly what I mean, I’d cut off the lower mount from the F150 shock and discard it entirely for a custom U bracket either welded or fastened to the standoff section, the only part of the factory MN12 shock I can see using is the spring perch itself, and that’s really only if the F150 one is inadequate for our springs.

I found that the F150 coil diameter is 5.3” but as you can see the spring diameter narrows toward the lower perch and I can’t find that spec anywhere. Our front springs are 4.75” IIRC so they may well fit the F150 perch if that’s close to what they narrow to.

I follow now.

Well you've always said these cars look like they have the stance of a 4x4. Now with integrating F150 suspension parts, you can make it a reality!! :ROFLMAO:
One of the cars on the banner might have inspired me come to think of it :ROFLMAO:

Ironically actually it seems a 4x4 shock would sit lower on our chassis than a sports car shock

F150 4x4

Extended Length (IN)21.89

Collapsed Length (IN)16.34

Travel Length (IN)5.55

Nissan 350Z

Extended Length (in.) 23.940

Compressed Length (in.)19.450

Travel Length (in.) 4.490

MN12

Extended Length 20.500"

Compressed Length 16.375"

Travel Length 4.125"

More travel but it could be mitigated to some degree depending on where the custom lower bracket is placed.

How about if the shock body happened to be small enough to slip into ours like the Bilstein insert mod. Would just have to leave an inch of the lower shaft to thread. I doubt we're that lucky.

I do have the inserts for mine, but following for future reference. F150s will be around for a while...
Wont work with these shocks at least, diameter for the B8s are listed at 47mm outer diameter, in S4gunn’s shockoptions thread he measured a Monroe Tbird shock tube at 45.39mm inner diameter

2011 to 2015 ram 1500 4x4. I seen these shocks several months ago, I didn't want to post until I can get to a parts store and compare, how wide the bottom mount is, and to see whether top shock mount can fit on the shaft. But they are very close to the F-150 4x4 a few post up as far as length and travel. I don't know someone may have already mentioned it but it's worth it to look into View attachment 43634 View attachment 43635
The 6” travel makes me a little uncomfortable where the F150 ones, in theory anyway, could be shortened to compensate for their 5.5”. Still another promising choice, who’d’ve thunk 4x4 pickups were so close lol

The top mounting doesn't look as desirable to me with the RAM shocks, the F150 ones depending on diameter might just slip into our stock style upper mount without any modification, the RAM one the threads and step are quite short, much like some of the other shocks we've looked at, requiring some level of custom fab for the mount.

Lol, Yeah that's why I was a little hesitant on posting it, being that was for a 4x4 truck and I want to have some comparison until I saw the F-150 shock post, now I didn't feel so bad.



Oh cool, I figured someone else would have seen them.
Hey, I thought I was nuts looking at the f-150 4x4 shock! Whatever might work is worth exploring IMO Travel aside(it'll just make the suspension droop more on jackstands) I like the Ram shocks better than the 350Z shocks, if for nothing else the spring perch isn't way up high forcing us to use Z springs. I have more confidence in the stiffness being higher too, I dont want to go through the trouble of making the Zs work and they feel exactly the same as my current Tokico blues

Thats why I was looking at them. And they also have Bilstiens and beltech makes a kit to lower the trucks, so if they ended up being stock height I was planning to get a front kit.

But again. No time.
Other thing I ponder with these is if an adjustable Mustang coilover sleeve might fit like Mercutio used on a stock shock body(with Koni inserts). The sleeve would butt up against the snap ring.


I’ll probably start experimenting next month after my surgery.

So I finally got myself out junkyarding to get dimensions from relevant areas from a mid 00s F150 FX/4



Perch

44218


for reference MN12 front springs are 5”

Shock body diameter

44219


The standoff to modify is stepped on this particular shock so I took both measurements

44220

44221


Mount thread diameter

44222


Frustratingly I forgot to get the distance between the perch and lower mount.

It probably will in the drift scene.

You guys wont like how my car gets as it progresses, I already know that. Stance and body mod wise.

However


Even though I like drifting, and I love these cars, I PRAY these things dont get propular like 240s. All the clean ones are instantly gonna vanish and get turned into missiles.

Admittedly, my cars a missile. But it was a POS to start. So Id rather keep messing with this one instead of *** up a nice one.
As long as you don’t camber the wheels and run 195s on 9” wheels. That’s dumb and cliched as hell at this point. Be original

I *** hate stretched tires so dont worry.

Im not cambering the rears cause again, thats stupid. But the fronts will be to make up for both caster angle at lock on the inside tire and the ackerman radius on the outside tire.
Might be getting names wrong but basically want the inside steer tire, which will be getting the most grip out of the two, to have a full contact patch. While the outside, which wont be getting a lot of grip to begin with, gets even less since itll be trying to roll at a different angle.
You’d be setting up the suspension as if it had struts, SLA suspensions gain camber in corners, they don’t need visually obvious static camber for maximum contact on the inside tread

I’m certain they won’t work, the shock body being too long because it’s on a standoff like the Z shocks(or F150 shocks) is one thing, they can be cut down, but with the LX platform shocks the body is too long, throw on a super low springs to compensate and you have no suspension travel. It’s really unfortunate as the ends are remarkably similar to the MN12 ends.
