Adjustable rear camber arms feeler...
 

With the number of guys lowering their cars and wanting/needing adjustable rear camber arms, I am looking at making them.

I have the parts and am making 2 sets as pilot runs. 1 set using 7/8" round 304L stainless steel for the arms and 1 set using 7/8" 6061 aluminum hex. I am using the QA1 alloy steel rod ends and making spacers to fit so you can use the 12mm factory bolts.

I know there are at least two other vendors. I would just be another option if there is interest. I can make them on order or if there is enough interest, I can make some kits up and have them available.

I should be able to have pics by this weekend.

edit: I am only making the stainless steel version.

Manufacturing....that will help with bills Mike...and you will be precise...I am not lowering though, so maybe I can think of something else you can build for me. I still need sights put on my new "New Agent" Colt .45...lOl

Re: Adjustable rear camber arms feeler...
 

if you make the engine brace you had a pic of i would be interested in that. maybe e some adj toe links?

Re: Adjustable rear camber arms feeler...
 

I already have the rear camber arms so ...... but if you want to invent something for the front, you know, that could go to -3º I'd be in like flint.

Edit: Oh oh oh .... adjustable swaybar links! DO IT.

Mike, You should concider chromemolly all of the race car companies provide the stock in Aluminum, SS and chromemolly. There is no reason for the weight of stainless.
I have a Modified Driver across the road from us and he makes a lot of them. Dirt track racers go through lots of them.

I bought a set from a vendor here, he's gone now. They were made of aluminim and work great. What I want is adjustable caster arms. He had them but he went out of business before I could get a set.

If you were to have a Chromoly part in one hand and a stainless steel part in the other you could not tell the difference in weight. Both are steel and the difference in weight is negligible.
Any part like this should be forged or cast if it is aluminum. Machined aluminum is risky as it may contain flaws in the structure rendering it prone to breaking. The aluminum would have to be treated to prevent corrosion. Salt will eat the part away slowly.
Taking the strains that this part does I would not trust my neck to an aluminum part that has been machined, the weakest part would be the thread which would fail first.
Aluminum is light but not too strong in tension and compression, steel nuts tightened too much could strip the aluminum thread easily. As the aluminum is softer the locking nut will be hard to keep tight as the aluminum will mushroom slightly and loosen the nut. Corrosion between the steel and aluminum is another possibility.
Depending on the stainless alloy used it is less strong than chromoly to a lesser or greater degree.
If you have aluminum parts I would remove them unless you are sure they can take the load and not suffer fatigue and fail suddenly as aluminum work hardens and then snaps. The person you kill may not be yourself. An insurance company would hold you and the manufacturer liable.
No aircraft would be allowed of the ground with a part like this made using aluminum.
Aluminum is not a good idea. I would be hesitant supplying a part like this for legal reasons.
Aluminum is used by some as it is cheap and easy to machine but not safe in use over the long haul.
The 300 series of stainless steels are not for use as structural members, threads in it are weak and tear. It is also hard to machine a decent internal thread in as it does not cut well.
Hex aluminum is cold rolled and may have flaws in it unless it has been x-rayed and certified.

Re: Adjustable rear camber arms feeler...
 

Dave is correct on all points made. But, in my extremely humble opinion, internal threads made in 300 series SST will be easily sufficient for this application. Many parts made for MB SLK's (MBWorld type) are swaged into tubing. Cold-formed. Worse possible scenario. Most tie-rod ends are made the same way. And they loosen and fail.

I'm making a pair of adjustable camber arms for mine. 316 SST hex stock, turned down in the center 2/3 to 9/16" for clearance and I believe I can tap the threads in such a fashion as to make them safe.

At least safer than aluminum. ;)

Re: Adjustable rear camber arms feeler...
 

I think I should have been a bit more specific; 304 st/stl is really stringy to cut and the threads are liable to strip and look like a Slinky. It is quite a soft material as purchased.
I presume you will be using left and right hand threads.
Personally I would rough out the internal threads on the lathe with a boring bar and finish with a good sharp tap that matched the class of the thread on the rod ends to give a nice fit.
My OP was more about the unsuitability of aluminum, a decent st/stl. would be adequate but 304 is not it.

Re: Adjustable rear camber arms feeler...
 

Given, agreed and you are right again!:eek:

Re: Adjustable rear camber arms feeler...
 

Here are pics of the set I have made from stainless steel. Based on the discussion I will only make SS. That is all I would use on my car anyway....

Re: Adjustable rear camber arms feeler...
 

They look good to me, and should do the trick really well.
If I may be so bold as to suggest a flat on them might be a good thing if they are not planned already. Tightening will be OK but loosening both nuts would be a problem and a pipe wrench would mark them up bad.
Good job.

Re: Adjustable rear camber arms feeler...
 

how much for a set without the heim joints mike?

Re: Adjustable rear camber arms feeler...
 

I may be interested as well. But as suggested, somethning needs to be done to prevent using a pipe wrench on them one day.

James

Re: Adjustable rear camber arms feeler...
 

Yes, I was thinking a 1/2" flat spot about 2" from one end. That will keep it clear of the spring, either inside or outside. If I cut .065" off each side that will make a 3/4" or 19mm wrench fit nicely....

Re: Adjustable rear camber arms feeler...
 

i am very interested

Re: Adjustable rear camber arms feeler...
 

I'm interested as well!

Re: Adjustable rear camber arms feeler...
 

same here. ive been in need of a set for a while now :D

Re: Adjustable rear camber arms feeler...
 

I'll jump on board. New wheels ordered, koni and eibachs coming next.

Re: Adjustable rear camber arms feeler...
 

Re: Adjustable rear camber arms feeler...
 

I'm interested also.

Re: Adjustable rear camber arms feeler...
 

Being I don't autocross (so far) would I really need this for the street?:confused: Mike,Haven't I seen that dragonfly fabric chair on this sight before?:D Squirrel Crusher

Re: Adjustable rear camber arms feeler...
 

The only reason you might need adjustable camber is if you lowered your car... lowering accentuates the camber and can cause excessive wear on the inside of your tires...

When I lowered mine my camber went to about -2.5 degrees..... I had them aligned to -0.9...:D

Too bad we cant do this with the front....:(

Re: Adjustable rear camber arms feeler...
 

Count me in. I just replaced tires on our lowered SRT and could not believe the wear pattern.

Re: Adjustable rear camber arms feeler...
 

I would disagree - there are other reasons for purchasing these. You may want to run a more aggressive alignment on a road course without chewing up your tires on a daily basis. Or the opposite if you are a drag strip guy you may want to run less camber when on the drag strip but then got back to a stock stetting for handling and stability.

Plenty of reasons to purchase these arms. :)

Re: Adjustable rear camber arms feeler...
 

Yes, but he did say for street use......;) and I like your thinking....:D

Re: Adjustable rear camber arms feeler...
 

So how much are these and how soon will they be available? I have my springs in hand and am ready to lower my car.

Thanks, Mike.

Re: Adjustable rear camber arms feeler...
 

I am interested as well, what price range are we talking about?

Re: Adjustable rear camber arms feeler...
 

Guys, I am making these on order with the low volume and short turn time.. waiting for rod ends is the longest time and that is only 4-5 days.

Price is $225.00 + $14.50 shipping....

Not the cheapest out there, but comparable. They are well done and solid.

Re: Adjustable rear camber arms feeler...
 

I have recieved my set of camber arms and am absolutely impressed.

They are the highest quality and I can not wait to put them on, unfortunately, life has been getting in the way, hopefully within the next few weeks, but who knows....

Thanks again, Mike, I would gladly buy any product you offer for purchase after seeing the quality here. I also have a few friends that are interested in custom length ones for their lowering applications, any interest in doing some 'custom' work? ;)

Re: Adjustable rear camber arms feeler...
 

John,
no problem doing different lengths.... all I need is the specs they want...;)

Re: Adjustable rear camber arms feeler...
 

I had Mike's arms installed at the dealership and the tech was able to bring my Eibach lowered rear into spec. He mentioned there is a factory kit for the front arms that is very inexpensive. Since my camber is still out of spec on the front by half a degree, I'm considering taking the plunge.

Has anybody ever heard of or used such a factory kit?

Also, because the aftermarket arms are straight and the factory rear arms curve around the sway bar, I now have less than 1" clearance from arm to bar. Not a showstopper but definitely something to be aware of when considering this mod, especially on a lowered car.

Re: Adjustable rear camber arms feeler...
 

Mike, just an idea. Why can't the adjustable arms have an arch to them? I realize you would have to at least remove one end to make an adjustment. But once you locked the arm back in the arched position, with both lock nuts, it shouldn't be a problem. Just curious.

James

PS, Maybe I mean more of just a slight bend in the rod, enough to give more clearance.

Re: Adjustable rear camber arms feeler...
 

This is well know to those that have been here awhile and have paid attention. It's not an issue on the street. If you race ie push the car to the extreme limits you will have contact between the straight camber arms and the sway bar with Eibach's and Dot 1 pads. I know because I had Eibachs, track my car, and had the problem. My solution was to lift the rear with Dot 3 spring pads.

Les

Re: Adjustable rear camber arms feeler...
 

Hey Les, If you were paying better attention, you would have noticed the first word in my post was "Mike", not Les.

James

Re: Adjustable rear camber arms feeler...
 

When Mike was gauging interest for this part your suggestion was made to him. But OK, I won't butt into you PM's.

Les

Re: Adjustable rear camber arms feeler...
 

First time post BUT...... Did you ever get this through R&D and available to buy?

Re: Adjustable rear camber arms feeler...
 

Yes, they are working very well....:D (got your email)

Re: Adjustable rear camber arms feeler...
 

Sorry to dig up the old post ( miss you Mike! :( ) Car is in the shop and they are failing me on the inspection because the camber arm is loose. I have not seen it yet but I assume it is just the end if it is loose. This is hard to believe though as these are built rediculous strong. Looking through old threads it looks like the end is a QA1 XM10 5/8"

Does anyone know if this is not correct or a good place to order from? I'll have the 15 day rejection period to get one in and swapped, will prob just pick up a left and right thread to make sure I'm covered. Thanks guys!

Re: Adjustable rear camber arms feeler...
 

I can't think of what you mean by the end is loose???? If it is the bolt to nut through the eye, then just tighten it up??? If it is thread to rod then the same thing? or am I missing something...
