[QUOTE=InfernoSTi]Does this help?[/QUOTE]
The question was essentially:
"Why is the stock geometry so much less than ideal even at stock ride heights?"
You answered:
" because the car wasn't designed to be 4" off the ground"
And you wonder why I was confused :rolleyes:
To answer the original question:
Subaru WANTS the car to understeer as it's delivered. Reducing negative camber with body roll is a very effective method of ensuring this.

Hey, friend, don't get onto me, please.
First of all, I didn't say Subaru designed the suspension one way or another. What I did was answer your question. You asked what was the post in response to--which I answered: it was in response to the earlier post. I understand that you don't think the earlier post answered the other earlier post. I guess the only way to know Subaru's intent is to ask their engineers. However, that won't change that the suspension is what it is.
Second, there are a bunch of aftermarket upgrades that are available that increase performance over what is offered stock. A nice set of camber plates is a good example. That being said, it seems foolish to sit around wondering why didn't Subaru design the car with adjustable camber plates. I would put this part in the same class of parts.
At this point, I just want to know if the part is reliable and effective at what it is intended to do. I am waiting to hear more about the reliablity part of the equation, personally.

Not sure if I posted this above...
The pieces are still doing great on my car and a number of folks, both passenger and drivers, have been impressed with the cars handling and ability to rotate with the street alignment.
Last week we hired a professional engineer to calcualte the loads and then perform the FEA analysis. The analysis will determine any needed changes in material or stress centers that could be evened out with changes in the design. This should likely be complete by mid of next week. The guy was stupid expensive but a PE stamp can go a long way.
Once, the analysis is complete, we go to production and our good freinds at TiC will start a group buy for the first run. The run will likely take 2 to 3 weeks to complete.

Initial analysis is done, conclusoins and design tweaks will follow shortly.
The initial FEA analysis indicated that the parts as designed will not yeild under racing conditions.... The computer confirmed that my car hasn't fallen apart yet ;). However, each piece had a stress concentrations that we want to resolve. One concentration, both I and the CNC shop were already aware of, and had identified a resolution through slight design tweaks. The other concentration was indentified and resolved by our PE with yet another slight tweak to the design. So, one of the two changes needs to be whipped out in the CAD and then rerun (click of a button). Although I trusted my design, I am very glad the computer agrees.
Once the concentrations are removed, I will finalize material selection.
If you divide the PE's bill by the number of pictures in his initial report, this little daddy is proabaly worth around $300. :lol: Enjoy.

Glad to see a very solid design, testing, analysis, and manufacturing process. As someone that is endeavoring to get a PE in an unrelated field, I obviously think it was a good choice.
My guess (without knowing the details---finite element analysis?) that the software the PE used to model and analyze the part was probably more expensive than what you were charged. The "simple" AutoCAD package we use at work is almost 4 grand, and for my classes (Matlab, MathCAD, DSATools) total over 10 grand if paid for by a business. :eek:
Back to the part, which we are all waiting for!

javid- curious what materials your considering?
| javid | 07-07-2006 10:37 AM |
For the ball joint we may go with a 400 series SS or a treated 300. Machining the 300 will be easier and then we can pick up some strength with some heat treating after the CNC.
The plan is to have the PE, CNC shop and myself all conferance on the material selection, that way we pick a material that is plenty strong as well as 'reasonable' to machine in the ways we are.
I just got off the phone with the CNC shop and the second CAD tweak should be complete today. :banana:

Really? I think those are pretty easy to bounce back out of the analysis the return force the part can withstand at a certain safety factor. Reaction forces are generally an output you can select to see as a result. Depends on the program I guess. It's cool because I am not technically a PE and I don't know that I will ever bother. ;)
But kudos on backing up your product. :cool:

You realize that we didn't have a CAD / IDEAS model of the front suspension right? He had to manually reconstruct the front geometry using the 3D suspension pickup points we sent him in order to calculate the variety of loads at the tierod and balljoints under corner, accel, and braking. Both Marshall and I tried to find some fully modeled suspensions but we had no luck...
Hind site being what it is I should have had you do all the initial work for peanuts and beer. Tweaked the design, rerun and once we were happy we could send all your stuff to the PE for review and stamping....

They are still working well on my car. We are headed to CMP this weekend for a time trial so they will get some time on course at temp with R-Comps.
I am still curious about the failure mode that you experienced with extensions, all my calcs show a reduced load at the ball joint. I can only imagine 2 types of failure modes, complete destruction (shatter, crack, or fatigue) and wear of the joint out of OEM specs. If the joint is wearing I would assume that you heard popping noises while driving untill you replaced it...
Am I close??...??

Right.
Mark, I can appreciate not disclosing your companies prior R&D efforts but any additional details on the type of failure would be greatly appreciated.
I have met some folks that think that 'loose' ball joints are 'bad' ball joints. They compare the forces need to twist/move a new ball joint (a lot) to the forces needed to move a used ball joint (very easy to do). However a new ball joint will loosen up after just a couple hundred miles of use. Given your business, I would assume that you are already familar with this though.... just thought I would through that out there.

Yeah, both work very well, corrects bump geometry greatly, helping the WRX reach 1.85 lateral g's with 245/45/17 Toyo RA-1's. After the incident @ St. Pete (8+ g impact) which pretty much broke everything on the car (and our intentions to run a full season as well), the ball joint extenders were in perfect condition, granted they ripped through the lower control arm on the left side, the extender wasn't harmed.

Yeah, I was never too concerned with failure from impact as the rest of the front suspension has designed weak points that easily deform.

Just a word of advice, coming from a person who works at a company with several hundred patents. You shouldn't discuss items you want to patent in public until AFTER you have filed. If not then the novelty is lost and proving no prior art become harder. Not that the patent office won't grant one, but you could lose a suit over something like this. I know, our competitors have on a few occasions.
Anyway, looks great. Nice to see someone actually engineer a product for once.

True, but a valid patent protection order in the US will stop shippments at the port. I know, we successfull have had millions of dollars of knock off asain product confiscated and destroyed at port...
Again, this is a moot point for what Tom is making, becuase like he said, I wouldn't buy something this important from a no-name. And it's not worth the money to go after a knock-off when the market is measured in friends and boardmembers, not tens of millions of dollars.
But a word of caution to anyone who does think of patenting anything.

[QUOTE=remowgn]Bump for updates! :banana: :banana:[/QUOTE]
Right, not sure how I forgot to update that. My co-driver went off at about 115mph early in the weekend. One tierod extension 'failed' when he hit a berm and then a sand trap at ~50mph. The inner tierod was also borked during the process and we never found a spare.
The 'failure' point (although I don't like to think of damage from a 115 mph off as a failure or 'short coming' for the part / design) for the tierod extension was right where we had a stress concentration in the FEA and had redesigned the part.
I am actually reviewing and tweeking the final changes to that piece as I write this.
The good news is that the car felt extremely neutral with just -2.5 camber up front and -1.5 rear (I used to run -3.25 and -1.5). I have played with the car on the street and it felt just as loose, but it was hard to confirm this until we got on track. The car also felt even better coming off the corners than it has before which I didn't really expect. Of course the braking is better than before. Hoppe was impressed from the side of the course, and my co-driver explained that I had really scared him in a couple corners.
I will likely run at Road Atlanta this weekend for just a couple short HPDE sessions to continue abusing the extenders and double check that I have resolved a spark issue we experienced at CMP. We believe that the out of the box plug gap is fine until the motor is 'track' hot at 400 whp / 21 pounds of boost at which point it start to mis spark.
Right, not sure how I forgot to update that. My co-driver went off at about 115mph early in the weekend. One tierod extension 'failed' when he hit a berm and then a sand trap at ~50mph. The inner tierod was also borked during the process and we never found a spare.
The 'failure' point (although I don't like to think of damage from a 115 mph off as a failure or 'short coming' for the part / design) for the tierod extension was right where we had a stress concentration in the FEA and had redesigned the part.
I am actually reviewing and tweeking the final changes to that piece as I write this.

Changes and the second analysis are complete and look great, all the stress concentrations are gone. I have to coordinate between the PE and CNC shop on materials and then we go to production.
Thanks for being patient guys! :banana:

I think that they would let it slide... rules like that are in place to keep the main forums from being cluttered with useless threads.
[SIZE=1]Of course, I could just say I ordered a set.... ;)[/SIZE]
