Jesus Chrysler!
that sleeper is kinda deceitful...reminds me of the guy with the $189 sharktooth at the....forget it
HAHA that is awesome! I really hope to see some of these road race cars actually road racing......Hey Wracks71...since you are the factory road racer...can I ask you?
for auto X or whatever it is called (roadracing).... what makes a coilover car any better than a torsion bar car? not a trick question or anything, but looking at your race car I see a wider/lower stance..wide, low profile tires....big brakes...no doubt, big sway bars. All stuff I can do without ANYONES coilover conversion. I have seen many race cars with front torsion bars...keeping the weight spread out and low on the car.
the big improvement for road racing (for me) would be to trash the leaf springs and go to a rear 4-bar set-up w/ locator and sway bar...adjust the bars to get in to plant...plus jack the weight where it fits the track.
my experience with the Mustang II front spindle is while it is a great affordable front steer spindle...it does not have the ackerman that the factory rear steer set up provides...the Mustang II is more of what I would call neutral ackerman...both turn about the same. I would think ackerman would be good for road racing/turning corners....but maybe you are sporting some "trick" race parts and not the over the counter spindles???
and since I don't think it is the secret to the nuclear bomb and you are the only A-body road racer I know... I have another question ....the RMS uses a modified steering arm on the spindle to correct (I assume) bumpsteer and it also appears to be lengthened a tad...does the added lenght slow down the steering and/or affect the turning radius where it is noticeable.
just askin' the expert
Damn Mark! Some things you should never sell.....but life goes on.

not exactly sure how to take your response....but I have always thought if the intended purpose is road racing...a beefed up stock rear steer set-up is superior. With tune-able (different length) balljoints and tubular uppers....camber/caster/ and the roll center are adjustable.
I'm no road racer...never claimed to be. that's is why I ask ..what you are looking for. Does my front end have the ability to "tune" those characteristics...absolutely.
Since it is raining out , let me bring up another point...
I get asked about alignment graphs/data, but what do the alignment graph tell you?
1) can the proper specs be achieved? most can do that even with the most Rub Goldberg configuration...do we need to show that??
2)what does the camber do thru suspension travel? I have shown ...not from graphs, but from pics that the camber change on my package thru travel is practically zero. Furthermore, for certain specific applications my package, like others including the factory, is "tuneable".
3) caster change......I build my uppers with bungs for adjustable poly-ends..or heim ends (your preference) to work with the factory cam adjusters. The caster is adjusted thru of the upper control arm pivot points on the framerail....and WE ALL USE THE SAME ONES unless you have installed a aftermarket front clip.
4) toe-in....here is the BIGGIE,...does the toe-in toe-out change thru suspension travel (the dreaded bumpsteer). ONLY if the lower control arm pivot point is in the correct location (with the other components utilized) can this be kept at the absolute minimum. Of course , there will be some minute movement, because the different length lower control arm and tie rod swing in slightly different arcs. I have always measured bumpsteer the old fashion way...with a guage mounted on the hub to make sure it doesn't move in and out thru the travel.
5) roll center...not in your basic alignment. There are two ways to change/adjust. The lower control arm pivot point that is set to achieve alignment specs....which leaves the upper ball joint pivot point to change/adjust the angle of the upper control arm. This is adjustable with different length ball joints/ ball joint studs. Same as most.
so back to the important graphs/alignment ....what does it tell you?
can you align it?...and does it bumpsteer.
To satisfy, when time allows ...I will head to alignment shop with the "mule" (actual Duster front end) and a K-frame package.....So much for the land of low overhead, but the data is relevant and understandable after some of the "packages" I have seen out there.
In the weight comparision thread, G Machine Dart GT asked a great question ....what is it intended purpose for your parts?
I will answer it again here...It is a great hot-rod piece...it gets rid of the 40plus year old steering box and the factory rear steer linkage and replaces with a modern, compact, easily accessable rack and pinion. It replaces/removes the torsion bars with coilovers, and sheds appx 30 lbs dead weight off the nose. So, lets see...no torsion bars ...no steering box...not limited on tire size...automotive tie rod ends....unaltered spindles....100% bolt-in with no welding or cutting on our A-bodies.
and to the OPs question.....to re-cap....mine is a somewhat different coilover front end...specifically designed for the hot-rodder. For the road race SPECIFIC build, I would probably go another route...but that's just me
Mopar to ya'

??? you mean i can stick a 33x12.5 up front?? lmao.
All of that info is super..........All that I cared about when my 71 duster was going to get your suspension
1) 528 Hemi
2) Flat hood
12 years of driving my hot rod with your front suspension .........
priceless.
??? you mean i can stick a 33x12.5 up front?? lmao.
I have 245/35/18 on 9 inch rims on the front of my barracuda with the RMS system
What's your point? I'm not laughing.??? you mean i can stick a 33x12.5 up front?? lmao.
This is great info! Now after reading it all it seems to boil down to the spindle and it being a mustang II style part, is there anyway to have a hub based version like a viper or vette (you get the idea).
What's your point? I'm not laughing.
They're trying to have a relevant discussion here.
Only have this one
"...It is a great hot-rod piece...it gets rid of the 40 plus year old steering box

accessable rack and pinion. It replaces/removes the torsion bars with coilovers,
and sheds appx 30 lbs dead weight off the nose. So, lets see...no torsion bars ...
no steering box...30 lbs lighter...not limited to a small diameter tire....integrated
bump stops .....automotive tie rod ends....unaltered spindles....100% bolt-in with
no welding or cutting on our A-bodies......."
And if I recall, the original purpose was to fit the 426 motor into an A-body with a
flat hood, Heater (and A/C), wiper motor etc.
Sounds to me like it should be $1000 more; not $1000 less.
you got that right Doc! I should have kept that car.......:banghead:
