New tubular control arms from Competition fab
Hey guys,
So if anyone noticed that ZZP took down their tubular control arms from their site fear not! I have been working closely with Competition Fabrications out of Maple Park Illinois on creating a new tubular arm using a superior design. The goal is to beat ZZP prices ($500) while using better materials, thicker tubing walls, and an alternative to the problematic heim joint. I am aware of 3 guys who had their ZZP arms break on them and Dave at Comp Fab and I are determined to find a design that will not fail under any circumstances.
I loved my ZZP arms, they dramatically changed the car for the better. The benefit of using beefier tubular control arms vs stock is obvious. The arm itself will flex much less under heavy loads. This leads to the near elimination of torque steer as well as understeer. This will also bring more of a solid feel to the car under any conditions and add steering responsivness, the tires will feel more planted into the pavment.
So what I need from you guys is a preliminary count of who is possibly interested. We're still about 2 weeks out from a prototype for my car, and after a week of testing I will be ready to start taking orders. If you are on any other W-Body related forums I would really appreciate if you guys could post a link to this thread on there and then post a link of the new thread on here so I can see what the interest is. The more intrest up front, the cheapier the arms get! This deal can only add more options to the suspension's of our cars! I also want to look into making an arm to be specifically designed for coilovers in the near future using the small profit from these arms as the R&D fund. But lets get this off the ground!
Please feel free to PM me if your not comfortable posting your response on the thread.

I would be interested as well, but I am in the same boat. Just purchased a TEP trans so the wife is keeping an eye on my mod spending
Definitely worthwhile, thanks for going through the trouble!

Very interested.. but in the same boat as everyone else. I wish I had this option back in November -- I just replaced mine with new (but still stock) arms.
But I'm otherwise very interested.

so as far as price, the money to make the jig and first pair of arms will be out of my pocket unless anyone else wants to go in on this whole deal with me. After that I plan on beating ZZP's price of $500 even considering development costs. As long as I break even I will be happy, all I want is a better driving car. Profit isn't my goal here, the only profit I'd like to see is enough to cover the R&D of a version of the tubular arms specifically for coil overs that will happen in the future. I'm talking real coilovers, not the threaded sleeve welded to a strut.
As stated above, we are in the early stages. Serious research began last week and it isn't rocket science so progress has already been made. We simply need to figure out how to continue to use the factory arm mounts while using somthing other than a heim joint that will have more give and absorb the shock from hard bumps. As well as come up with a shape for the arm that will add rigidity, we are thinking more along the lines of a true A Arm shape, or at least as close as we can get without adding another control arm mount to the sub frame. This was the downfall of the ZZP arms. These new arms will be made of much thicker chrome moly steel with a much thicker wall. If we find it necessary, or just as good insurance the arms will be gusseted as well. I want nothing short of a top quality and designed product, I will not stand for anything less anymore for my car! At my day job, the motto I created for the company is "do it right the first time", very original I kno , but I intend to do the same here.
A rough time estimate is 4-6 weeks until production can begin. So I would start taking deposits a week ahead of time. I'm not going to promise a product until I'm sure I can deliver it as represented. I want the prototype installed on my car so I can confirm the performance 1st hand.
If anyone has any input, suggestions, or ideas I'd really like to hear them!

If I were you, i'd do 1 of 3 things. 1st call ZZP and tell them you feel unsafe based on proof that the arms have failed in the past, if they say go F yourself you can scrap them. Or you can get in contact with a guy like Dave at Comp Fab and have them gusset up the ZZP arms so its not a total loss.

The theory is they make the torque steer significantly less. Nobody wants to take the liability risk.
Google Ron Vogal. I think he made made some for a gtp a few (~10) years ago.

There's a lot of Ron Vogals showing up on google, I tried adding suspension and control arm to the search and came up with nada.
PLEASE repost this link and sentence in other w body forums, and when you do, post a link to the new thread you just made on THIS thread. The link to the main thread on LS1 tech is below, i will check every thread that has a link. Thanks, V8ImpSS

No, not quite yet. Dave at Competition Fabrications is a busy guy, building dragsters, race cars and all. I'm hoping to be able to get a final design by week's end, but not for sure. I'm as eager as all you guys, my car is currently decomissioned until I get some new arms. If you are subscribed to this thread, you will be the 1st to know of any progress that has been made. Both dave and I are currently finishing up some R&D, I've talked to at least 5 other suspension guru's to get their input, but theirs a few other bases I wish to touch before production.

V8impSS: I am currently building a set of lower control arms now for my Monte. I will be using 4340 tubing with .093 wall if I can get it, if not .080 will suffice due to the strength in the 4340. I will use the stock arm as a pattern with the addition of gussets to reinforce the basic triangle design. A poly bushing rearward, a Moog bolt on ball joint and to solve the heim joint issue I am using a Jony Joint fitted to the cradle that will adjust in a welded on internally threaded tube. All welded up and powder coated. I originally ordered the ZZP control arms but glad they never delivered, now that I hear all about the breakage. I hope this helps you.

Yes it does, we're planning on involving the jonny joint. Ive talked to a few people at currie as in john curry, inventer of the johnny joint. Thank you for posting your information!
