Guys, we're kicking around the idea of a replacement control arm for the Delta. The control arm will consist of an entirely re-worked, engineered piece that will be designed as a direct replacement into the Delta platform.

We're definitely using chrome molly steel, which has great weight properties and is very strong. The arms will be tubular, to maximize on weight reduction and strength.

The rear control arm bushing will be replaced with solid spherical bearing units, this will eliminate deflection and allow. The forward control arm bushing will be a two-piece sealed polyurethane unit and the ball joint end will be modular with a heavy-duty replacement ball joint.

The ideal test car will be a Cobalt SS/SC and development time will take up to 3 or 4 months.

Current modeling predicts an estimated Price of $700-900 for a pair of these units.

We would like to see some interest and paid commitment of at least 6 people before we can go intro production with these units. The first paid five will receive a significant discount, and the first test car, will receive a pair for free, including free installation (if located in the Toronto Area).

 

Wow!
I would be interested sometime this fall (Aug-Sept), as I'm still working on power upgrades for now.

Do you have any idea on percent strength increases, weight reduction, etc?
What grade of material will be used? Size?

 

Mev,

i love the spherical bushing, finally a much more significant answer to wheel hop.

when are looking to start testing? I've just about sealed the deal on my new truck (08 silverado) and if the time frames line up would be more then willing to drop my car off with you guys for initial development and test-fitting. then pick it up and drive it around, ect.

you catch the drift, would this a do-able situation for you guys? your not much of a drive from my self.

 

I think most of us here are pretty sick of financing everyones development costs

Come out with the product, test it, then tell us about it

 

angry twinscrew person?

 

Then don't buy it....

Jeez... I'm sick of people bashing...

Marco and myself have addressed the issue with regards to strength and weight, the type of material is definitely 4130 Tubing. But we'll definitely have to coax contours and stress reliefs with our 50 ton-press to shape and fit the control arms. Remember, CMS doesn't like to be bent without serious fracture. All this has to be taken into account. Also, the spherical bearing control arm bushing at the moment is quite complex to design.

JBP is going to be competing in CSCS this year, so we need a consistent launch and reduced wheel hop for our FWD race car. (Formal announcement to be on our website close to May).

Further details remain under we get a formal drawing out.

Yeah, it will be superior. And we can say goodbye to polyurethane degradation. When we get 5 comited individuals, we'll start the prototype work. We need two sets, one for testing and one for sampling for drawing and redesign. From this point on, we are pushing R&D times our by 3 or 4 times. Which means that all our products get redesigned about 6 or 7 times during testing, which leads to a better product and less problems in the future. It won't be released until testing is complete and satisfactory. Which is why we give almost half a year until release. Long wait, but worth it for product quality.


It's not financing, we've got the money. We're looking to ensure a good market response before making something no one really wants. There's enough people out there who pipe up to lend interest, but typically back out when the time comes. 5 confirmed buyers = a reason to make the product. Others will matriculate as reports of the product hit the streets and we cover a wider band of customer base. If it was just about funding, then c'mon we'd say that. Regardless, I see what you're saying, it does lend a little bit towards the fact that we retort the initial R&D costs with the 5 confirmed buyers. Hey, every little bit helps in releasing more product, no?

Could be, not our place to comment.

It comes with the territory... as a business, we'll never argue over the internet, you never come out on top.

Not sure what that means, but cool!

 

It means I'm interested enough to want to be able to find it again, with ease...

 

Will this polyurethane hold up better then the Control Arm Bushing Polyurethane?

 

Thats good to hear.

with an unknown start time for R&D I'd just assume to get back in contact with you guys on this issue once things are straight from my end.

agreed?

look to hear from me with in the next week or so.

 

excellent

The polyurethane bushing in the front of the control arm does not see the same load as the rear unit. Regardless, we've come up with a two-piece design that encapsulates the bushing and prevents tearing. No more failures.

We'll stay in touch...

 

4130... sounds great!
I assume that you'll be using heat to relieve the internal stresses, in combination with other proven methods...

WRT the bearing control arm... will you guys be using FEA to speed the design time or verify mechanical stress points?

 

im intrested provided you post pictures of the product on the car and in use.

 

FEA will be used and before the neigh sayings pipe up, we're going to verify in the analog realm as well. hence the test car, which will see some grueling punishment... (nothing too harsh).

 

Update, after a brief open-table discussion, we're making the entire unit solid. This means no polyurethane...

 

now thats more my taste.

 

nobody is truly interested in this product anymore?

 

Interesting but I can't wait that long so I'm probably gonna have to go with the other companys modified control arms
