Mustang Ii Front End In 48 Ply

[jimainnj]

Anyone have this in there 48 Ply, if so do you have a problem with hard ride ?

[Don Coatney]

I dont but define hard ride?????

[Plymouthy Adams]

the suspension is tried and true and tunable to the weight of you vehicle by correct springs etc...the ride should be nice and smooth..very responsive..the only draw back is the extreme you have to go to for installation....the spring boxes of the original suspension is in the way making the unit to undergo serious cuts and boxing or flat rut in front fame rails then the Mustang II to that...very very expenisve but you get what you want..there are other easier to do and less costly methods of clipping the front end of these cars but that is another story in itself...both take the avenue of no return to stock once started.  Raed carefully and be sure this is what you want and and I am guessing you intend to do this work that you have the tools, space, and equipment to make this come about and you welding skills are up to speed.  IF farming out...then just write the check and let the pro's do it..no need to concern yourself as they will more than not do it right the first time..just ask for references etc.

Other than the adaptability of these components, I don't get it. Did any of you ever ride in or drive a Mustang II? They plowed through turns terribly, rode horribly, probably due to short springs and short A Arms. Dove hard under heavy braking, wore out front tires. The fact that they are easy to do disc brakes and rack ad pinion steering is the only positive I can see. The mopar system with new springs, and relocated shocks will provide as good or better performance.

I have a Fatman MS2 front end on my 50 Ply wagon. I just got the car up and running and it rides and steers like a new car. Tim is correct in saying the right coilover spring rate is the key to proper ride height and ride.

[jimainnj]

Your right, no info no answer, I got the 48 tis way, MII front, 350 chev engine & trans

10 bolt chev rear. power brake's & steering. Hard ride ? feels like I have run free tire's

like my corvette, I don't know if they put the right springs for the front weight of the car,

and I don't know what the 48 front weight is. Thanks Jim

get an assessment of the cars alignment and verify it is in specs..your castor angles may be suspicious.  You can go to a local truck stop and get the front end WOW measured for the front and then suggest overall weight be read.  your 'run free tires' is this an error and you trying to describe 'run flat tires'....do you know who built the vehicle if not the PO?  this information should be available from the PO if he retained the maintenance papers when aligned..

[Dave72dt]

Run free or run flat tires?  Ride is subjective to the owner. I don't have run flat tires or a Corvette so I can't compare, plus the early Vettes rode and handled differently than ther new ones.  I do know the narrower the  sidewall on  the tire, the harsher they ride.  There's very little give in the sidewall of a 40 series tire compared to 70 series.  Shocks can also make a difference.  What type of spring setup do you have?  Are you hitting the bump stops? Adjustable shocks?

My P15 Club Coupe has an IFS and a small block Mopar w/auto trans.  That shouldn't be much diff. than your Chevy combo.  The front of my car, with me aboard @ 200 lbs, weighs exactly 1806 lbs,...or 900 per side.  That should be adequate info for a legit spring shop to confirm that the springs are too stiff and to get you the correct spring rate for your MII unit.  If you are doing it yourself, pull a spring and take it to a shop where they can measure the rate and provide the correct replacement.

And, I'd strongly suggest that you find a real spring shop whose business specializes in spring/suspension repair, (they usually do a lot of comercial vehicles), and NOT your local franchized alignment or general repair shop.

And, and,...after reading the post by Dave who beat me to the response   , yes, low profile tires are significantly firmer  because of the reduced side wall hight.  His comment about bump stops applies as well.  Be sure you're not riding on them.  Bottom line is for you to record and understand all the idiosyncrasies of your suspension system in order to address the issue if "stiff ride".  It's not rocket science but may require a little trial and error.  However, when you get it where want it, it's a very satisfying experience.

Good luck, keep asking questions and keep us up to date.

I thank all for info, I just got the car this year it was completed before I bought and

they new nothing about the build, The tire's are P215/75 R15. I looked at the spring's

and they only have 6 coils and very close together not much more than 9" long, and seemed to be about 1/2 diameter I changed my last 47 P15 spring's and the where a lot thicker.

My hard ride is probable bottoming out, I'll let some else change these doesn't look as easy as

the one's I did on 47 P15 stock.

[Plymouthy Adams]

was your IFS a weld by number set up or a manufactured setup prebuilt and delivered...if so who was the supplier...they may have built with wrong spring based on stated information from the builder....say it be a Fatman or Heidt etc even so the systems are the same and a call to the these companies will more than not be your fasters and more correct manner to attain the proper rate spring...suggest you contact their support department..surely they will know the rate..and are the springs you got marked..often they  are coded by number or notches on the bottom coil...if you look and find any marking be sure to relate this to their rep...odds are they will be aware of what they are and their rating and will be able to adcise from there...your tires are such that the ride should be smooth...is your steering labored or is it borderline or flat out just too quick and does the beast want to wander/road walk..and again..has it been aligned and the specs defined?  This is also an important detail to have on hand when talking to the reps..about harsh ride of the IFS

In California, you cannot take a picture of a man with a wooden leg.
...Why not?

 

 

unless the leg has a built in and lens and shutter...I would use a camera

[jimainnj]

I don't have info on IFS or the supplier (or who redid the car I know it was done in Alabama 2009)

I could not see the bottom of springs or any marks,I know I used ESPO 13" springs before and they where good for stock P15. Older Mustangs had soft springs about 350lb originally, as far as steering it's not fast and the return to straight after a turn is not fast either, I'll find a good shop and have them check it out. Other than that the car is 100% looks and shape.

[Plymouthy Adams]

I can understand you question and position but not much can be done here on the forum except to advise..and to that end facts are needed...I still feel your best answers are going to come from one of the aftermarket suppliers of the Mustang II IFS be it in kit form or complete...just a quick call to them with the actual WOW (weight on wheels) determined by a set of scales at the local truck stop or maybe even your local drag strip as they do the weight check during tech inspection...appears the car is driving and tracking only that response is a tad slow and the suspension seems to be bottoming out..does it actually hit the bumps on a normal street drive say carefully entering exit a driveway, a few corners as you go around the block or crossing a moderate rough railroad track..have you tested your shocks...granted only 4 years since install and probably few miles..but...are they dampening...

[mrwrstory]

Now you're talkin!  How 'bout a pic,...or two?

[jimainnj]

I thank you for the advice I called speedway motors and asked about Mustang II kits, they said if

I know the front weight they could tell me, I used the earlier post on weight and used 1700 lb

they said use 700lb spring, but said I need to test the spring that is in now. Well I'm just

going to the hotrod shop in our area and let them fix. You can't push or jump on the front and

get more than 1" deflexsion I don't know how too post a pic?

[Plymouthy Adams]

If you have a good rod shop they can get this fixed in heart beat...shame you hve to do what whould have been done first go on the build but then again..this may have been the ride he wanted....I do not think you are bottoming out I think your rebound is so stiff that the road transfers all imperfections to your butt while in the seat...

 

good luck...

On my 50 Ply. wagon- Fatman frame stub for MII suspension, chev v-8, 700R-4 trans-

Started with V-8 springs= 0 bounce with 2 people to = weight of front sheet metal- $75

V-6 springs,same setup= better Another $75

4 Cyl. Spring= nice feel with 2 persons bouncing on front frame, stock type new gas shocks installed. Cut 1+ coil to lower to height wanted. Another $75 but works good.

 

Best to ya, Changes almost never come easy.

That's a great looking car.  By the front end elevation, I'd say you're probably looking at a spring issue.

And ask the guy who does the springs, if you can swap out the new ones for a diff. rate if they are still too firm, or too soft.  Most serious shops will do that.

I saw a Mustang II driving on the street this week.  I have not seen one on the road in years!

The critics don't like them, but the fast back model is pretty hard to find.
