So a Chevy guy made the effort to register on Moparts, then post over 100 times? Wow. I did notice he painted his Chebby a Mopar color. Guess he regreted his Chebby purchase and it was too late.

Maybe he should swap out the GM suspension as well for Mopar stuff so he will be able to comment on this topic with some experience. Poor lost GM soul.

I believe he also is building a Mopar. Maybe he doesn't post here often because of the "haterade".

This post ran it's course 3-4 pages ago. Now all that left to do is pointing fingers and namecalling.

most of us have heard of (and remember) the ramchargers (no not the 4x4)it was a group of chrysler engineers that on their own got into racing, then they morphed into designing/building better engines and suspension team that was funded by chrysler---anyone heard of gm or ford doing it? other than bringing in a one shot wonder to develope one car...when the After market started chasing the sbc and ford 9 inch with developement---- chrysler opened up direct connection to get some tested development to the mopar fans to help keep racing on a more even keel...

Maybe he should have represented that instead of being a Chevy guy first and foremost.

As for haterade, he went that way with his snobby "1970 living" crap. So take it up with him.

No need to beef up the shock towers with the AlterK. The upper shock/spring bracket is part of the AlterK. You don't use the original shock tower, as I understand it.


I agree

My "next to do" on my Mirada was to get a tube K and coil overs done to it. Would have been great to get more weight off the nose of that car and get a little more front end travel. Unfortunately I parked the car and never got it done... and then decided to get back out racing and sold the car.

..... but our Duster is currently at the chassis shop getting a full cage and tube K set up.

Look at that bottom control mount and you will see what Rick is talking about. Panic stop a 3500# car and it might brake off or after a few thousand miles the wear on that bolt. Now look at a stock strut bar, much better load distribution. That is the major flaw of this system.But would be easy to fix by adding the bar so it lines up to the center line of the lower bolt so they both rotate on the same axis.

Also, the claim that all the load of the front suspension isn't supported forward of the firewall is wrong. Draw a free body diagram of the lower control arm, looking at it from the front of the car. the lower control arm mount point (LCA bushings) react all the vertical and side load on the tire. this gets transferred to the car in the K frame mounts....ahead of the firewall.




I'm with Patrick on this one. Most of what E-berg says in his magazine reply I agree with. However the loading on the front sub structure is identical between the two suspensions. If you have never drawn a free body diagram this may be difficult to accept.

Panic stop a 3500# car

Semi panic vid at #3250 at over 120mph, nitrous explosion, the stop was pretty smooth in the vid, but the front rotors were purple after this stop.

My brakes never lock, but with both feet on the ped I can almost get them to, I like it that way, with the bias adjustment.

With 4 wheel disc and good bias I was lucky, id say one more second at wot and id not of made the stop before the fire station.

My frame rails are braced from the front to the trans tunnel mount where the cage and frame connectors meet.

Yes this was very foolish on my part, but as a street car I run it hard...could I have stopped the car with oem brakes, susp?.... I dont think so, but thats pure speculation on my part.

No doubts the f body oem front has alot to be desired but I feel im in the small% that can use the RMS system as a true upgrade.

It was hard to spend more on a front end unit when many f body cars sell for.

J body, you had more front end travel with your oem front end, but you gain the adjustability and the ease of it. As the springs are only 9 inchs tall and take at least 2 out for adjustment and what the coils take up. But well worth it. Some run 350# for the track, I like #300 and as known the caltrack/monos lift on launch vs squat.

I was very lucky that day, a few hurt parts and some paint work and all was good.

The only mod I did with my alterk was to mount the steering arm eyelet on the frame rail va as placed on the unit.

I do inspect the unit each time everything else gets checked, the only thing ive had to keep an eye on is the lower control arm shaft bolts on each end I re locktight them from time to time and yes the set screw is tight on the shaft.

Panic stop and then some, but really with a pretty well built car and staying calm only the vid makes me skiddish....

I think that Rick E has done an excellent job in explaining how he formed his opinions of the AlterK. I am not an engineer, but there are a few things in the AlterK that scare me off.

I wonder if AlterK will consider addressing these issues, perhaps with a slight redesign?

are you talking the zinc bolt that has the sliver washer on it in the pick??? Cause that bolt wouldn't break in a panic stop that bolt just keeps the steel shaft from moving foward or back. The load is on the steel shaft that runs thorugh the K-frame supoorted by 4 poly bushings in a welded tube. I can't see that failing from a panic stop...

See, thats the thing. The reason I love Mopars is the great engineering that went into them in the day. T-bars are just one of the great pieces in them. Perhaps that's why I'm not crazy about modified ones that cut the unique bits out. If you modify a Camaro or Mustang you are improving it and it came with the inferior coil springs from the factory anyway. When you chop the T-bars out of a Mopar you've took away it's heritage and superior engineering, you might as well cut up a Yugo instead.
As far as Mopar Action being in the past, I don't find that to be true at all. It's the only magazine I buy, but when I quit buying it, it will because the articles on Red E-bodies with modified new "Hemis" and coil suspension overpower the interesting tech articles, it's getting pretty close right now. I bet they've got another two red E-body's with 5.7's lined up right now for the next issue. They're just like the red Camaros that Car Craft used to run.
It is also the only mag i get and i feel the same way.

It looks like the control arm is on the wrong side of the car. The angle of the top of the ball joint should be level with the floor with the control arm attached to the factory mounts.

Yeah.... This is MUCH better than stock!

How do you mean it "is on the wrong side of the car?" And when measured out, the instant centers and roll center IS much better than stock. Also, the camber gain issue has been resolved and the bumpsteer corrected. And it's much lighter and headers fit much better. Idk, would you call that better than stock?

First time I've seen the pivot points on a control arm not be in a straight line with each other. I don't know what kind of issue that might have, but it's different...

The upper control arm now swings in the same plane as the lower control arm. This eliminates the caster gain. Theoretically they are in a straight line because it is just 2 points. I chose not to cut and reweld the rear upper control arm mount, opting to use a high angularity heim joint.

Wow! That does look like junk. It just shows that those Chrysler Engineers years in school was put to good use not designing something like that.

I'll add that I also agree that the means RMS used to eliminate bump steer seemed odd. Rick referred to it as a "cantilevered" design.
In smoothe surfaces, the design probably works fine. Imagine taking it on the neglected roads that we drive on every day. The dips, cracks, ruts and potholes would certainly take a toll.




my alter-k has been in my dart since july of 2006. its all crappy pot hole (should see my road. wish they would fix the damn thing soon) dip all over south jersey/pa roads driven. system has held up fine. all original heim joints and all. i grease everything every spring while i'm checking the car over for the summer season. if it wasn't a 80 mile round trip for work or gas was $1 a gallon again i would daily drive the car. no doubts in my mind that the system would hold up to daily abuse. only issue i have is that the paint i used on it when it was new is falling the hell off. that pisses me off..


You actually snuck in a DOUBLE swear and got away with it..
