exactly. i wanted these arms to be tube steel because im more interested in strength then weight, because a flexing light arm will not do anywhere near the amount that a heavier steel arm will do. and btw, these are def lighter than the stockers. not as much as the aluminum ones, by far, but id say splits the difference. ill weigh my aluminum ones, these tube ones you already have the weight of, and ill weigh the stock stamped ones when i get em off of my car. ill also do print outs of my car on the alignment rack with the ball joint in the extreme neg and pos camber positions to let you know how much room you have to play with it and fine tune it.
if you guys think this is cool just wait till you see what happens next...this is gonna be a good year for j-body suspension mods, wouldn't you say mark?
I can't wait to see the reulsts on these arms. Just by the look of them you can tell they'll be a huge improvement over the stamped stockers.

And I've been thinking about it, since I can run it in street mod.

I've actually been looking into that already
well, i was looking into that but mark and i were talking about it and we think that it would not be affordable enough for the jbody community. so instead we have something else in mind that will still be a huge improvement but much more wallet friendly.
Watts linkage? Why would we want that? We dont have a solid rear axle, we have a trailing arm suspension with a retarded huge swaybar with a non-linear rate and wimpy brackets. I mean you want irs on this car super cheap, cut the twist beam out, put better bushings in the trailing arm to chassis section (oil impregnated bronze would be nice, for this idea or just in general), beef up the chassis mounts so they wont just twist to pieces, and put a mondo swaybar in thats correctly designed, like the one whats his face made who actually did the twist beam measurements.

Mark, what's going to be done with the replacement parts for these control arms?
Are you going to be keeping the spherical bearings in stock or at least provide us with a source for ordering a replacement part?
Heims and spherical bearings don't hold up to daily driving too well but for competitions purposes, the bearings are the best.
So for those that's going to be daily driving these for a few years are going to need some kind of replacement part.
Other than that, *likes* ..

Thank you Dave and JBO! 
Blu, We have replacement bearings in stock at all times. We can ship them out within a couple hours and you will have them in 2-3 days.
The bearings we are using and the Heim joints are either lined with PTFE or Kevlar. They should last around 2-3 years. if you keep them greased, they will last longer.
We noticed that if at every oil change you shoot the bearing with some "PB Blaster Spray Lube" the bearing stays cleaner much longer, just an FYI.

I want details on the suspension ideas!
Currently #4 in Ecotec Forced Induction horsepower ratings. 505.8 WHP 414WTQ!!!
Currently 3rd quickest Ecotec on the .org - 10.949 @ 131.50 MPH!!!
i would be intrested if we could get it down to 450
as for greasing them, will they be tapped with a zerk in them to be greased?
and agreed, provided they pass RIGOROUS TESTING, i mean ill pay what ever price they are, but $450 always sound better to people... in cavaliers and sunfires...
For the front bushing it will be poly. You can just apply grease when installing. For the rear bearing, there is no Zerk fitting. These will be greased upon shipping and you will also get a package of Teflon grease for the 6month and 1 year greasing. All you will need to do is put a dab on your finger and wipe it around. Should take no more than 20 seconds a side.
The NON GB price will be $550 for the set. If we do a GB price of 10 we will be able to release them at $425 shipped.
For the testing, yes they are being tested as we speak. SO far they are running strong on the customers car. There are a few minor issues to be resolved, such as adding holes for ABS harness plugs, trimming the gusset up 1/8" for a little more clearance, etc. Overall the customer is happy and things are going well. Lets hope for a 1 week review worth of celebrating

Id like to see these tested in a drag application and an autox application.... Just to get a LOT of stress on them. Nothing like having one magically break during a high stress point of some sort. Not sure how all to test them but I'd like to see them under heavy load.
but i can see 10 sets being spoken for.... then6 pulling through... i mean this is the org. provided they pass rigorous testing... im in regardless.
They will be tested to the extreme you can believe that. I think putting a set of control arms to the maximum testing in necessary. These will not be released until they are test and true.
