UAS Pivoting Upper Control Arms GB Discussion thread

WOW

Yep caught us out it is all made up. Black baz Not, part of this GB, what is it like to live in a negative world? Ross, better check if part of this GB, and who have you been talking to, and what does that mean? Saying we are illusive, throw it out there.

Rob is going to Bosenjak Engineering this morning to take pics and get update. We gave accurate info previously and this for some negballs was used against us. Hard to please. Yes way overdue, yes costing UAS way more than what was shown and agreed to as MUCH better in many ways. Lots of engineers and fabricators, welders and other machine shops making components and zinc platers etc.

Anyone wishing to pull out fine and just let Rob know. Rob does a great job, imagine if no Rob and had to deal with me. There is the lead in for the piss heads.......................

 

Rob, thanks for the update and pics.
Looking forward to these being 1 part of an eventual complete suspension makeover.

 

Hopefully this will silence the howls for blood from those who profess to have little, or no, engineering nous.
Thanks Rob, sorry you have been the 'Whipping Boy' on this disgusting thread.

 

good work rob..


make sure i get the first set , lol,, i joke i joke ....

[TIS]( I'm allowed I'm Greek ) because i am sparta ( thats cool )

 

Mister squiggle

lives!

 

robbbo mate u are the man. u have copped so much friggen flack over this group buy. i for one am very impressed. next time your in perth ill buy you some beers

 

yeah well done Rob I've been applying pressure without criticism, and am thankful for the comprehensive update and for your efforts in taking the day off to visit the workshop in person

cheers

 

Rob is the best

Big well done again Rob. No conspiracy after all.

BTW for everyone?s info for those who do not know of Terry Bosnjak. He is a very rare individual, being a very experienced and successful race car driver, and a mechanical engineer, that also specialises in making components for high performance road and race cars. To get all three is rare and one of the best in the game in all three.
His experience racing with Collin Bond in is Ford Sierra to Porches Cup, to Production car racing and many more. Setting lap records in various cars and tracks. How about 1 min 39 sec for Eastern Creek in a RX7 SP with only 300 flywheel hp.

Terry and his company specialises in brakes, suspension and drive train. He has the latest equipment including C & C machines. For those negballs making fun of Terry's company and his ability earlier in this thread about cotter pin design or fixing system, especially from someone with little experience and not qualified is bold ignorance. For the moderators to let it go to some extent is also a concern. Then there is the relationship with UAS and Rob who so often puts his time and effort into these GB's, mostly with some thanks but a few rare trouble makers, who do not understand that in life, If you throw dirt you only lose ground yourself. There is always a small percentage in every crowd that like to cause trouble, which is a shame and something I find hard to understand. To attack Rob who is a keen enthusiast and volunteer, is really a sad example of human failings. Probably why we have these stupid wars and killings around the world I guess. I am not against feedback if constructive and not counterproductive and under mining. In the past I often ask for feedback. In the past there have been some qualified people on this forum give some great input, and others that are very experienced and have a lot of common sense also with good inputs.

For those involved in this GB you will soon have your top quality product that has taken way too long but in doing so is a better product, that is more expensive but no extra cost. It has now been around 4 years in development and testing and redesigning. Numerous Motorsport Engineers, Automotive and mechanical engineers have been involved with this including the boss of Fulcrum Suspension, the largest Suspension company in Australia, himself and engineer, involed in the original design and earlier redesigns. To make fun of all these engineers, or implying some conspiracy theory is extreme. Yes it has been delayed and taken far longer and more involved than e thought, and financially very average for UAS, but hopefully long term it will kick in. I know some live in a perfect world and think you just click your fingers almost, saying can be made ina few days is a ..........

On a positive note we have more items being designed and machined at Bosnjak Engineering that will also be great products. We are not releasing until near ready, so no frustrations with delays like this one. Stay tuned.

 

Looking good, bloody good, Cheers Rob!

 

ok .. will try again ....

.. for the technical gurus out there ... my question is serious, simple and is generated from observation of two sets of Arms fitted to my two zeds ....

... are these Arms fitted with bushes or with bearings .... ???

i cannot tell from the pics provided ..

 

Hmmm really

Not sure what your question is, and I was about to say not sure what you are up to, and why you are asking questions about a product in this GB you are not part of, and will never get. But then it is obvious you just want to stir up crap. Last time I gave info on this product you managed to ridicule the experienced qualified engineers parts he is using. Your negative posts have been deleted of late, which I did not get to see, you have received PM's from members of the forum INVOLVED with this GB explaining things, and to back off. I have also sent you a PM with no reply, to try and keep things off the forum. PM me if you really want to know things.

 

Baz wants to know what is going in here:



There would have to be a bearing or a bush (I would assume a bearing would be more suitable for this design).


I'll be keen to get my hands on a set of these to see how they work, I can't quite picture it in my mind and from the pictures and sketches. If they work how I think they do maybe a small grease nipple might be of use as I can see these getting pretty squeaky (like any rose joint that gets dry and full of road grime).

 

OK

Sealed bearing, which can be replaced, but much less load as the arm has no twisting force as it is allowed to pivot, so not trying to tear apart.

 

I though he might have been asking about the pivot bush/bearing area.

ross

 

No bearings as such here but tempered and hardened, superior metal to test samples, which as Rob mentioned were fine in a big hp road track car for around 2 and half years now and regularly checked with no problems. They are not spinning and only move, or pivot a very small amount. Lubricated with Molly grease and sealed with an O Ring. Keep in mind they are under far less load as not binding unlike OEM and all other arms on the market. Also unlike the test sample the main bodies have been machined so they slot into each other, without the need for a jig then Tig welded, not Mig welded like sample. Other improvements are better metallurgy and treatments and cost more as previously mentioned, with only one real change being the Cotter Pin, instead of a grub screw.

I hope this satisfies the curious ones and settles concerns.

 

Lots off untested changes there, hope there as good as expected for all uses.

ross

 

... and would it not be even more comforting, satisfying and informative to all if answers were available for those three, basic questions (now hidden) ....???

 

Hi Ross, which parts are untested? Yesterday you were happy with the Cotter pin improvement? Surely not Mig welded butt joined, over extra effort to design and program countersunk joins and Tig welded, and core hardening components and tempering. May not be good for Rally Racing, but then nothing is, and zeds are not good as rally cars anyway.

We could do a destructive tests but this takes more time and money, and not needed I trust Terry and the road testing we have done. It may not be perfect yet, but very unique and the best after market arm on the market I am sure. Everyone should be concerned of the aftermarket upper front control arms that often tear apart, mostly made in China, or urethane bushes that flog out in factory arms, often quickly. Most know this and why there have been so many involved in this GB. On the testing point, what testing have the other top front control arms on the market had or engineer involved, probably none. I know Ross knows this. Also probably never seen and engineer, unlike ours which have had many involved with these.

The real test though is the many cars going to be using these, over years and thousands of k's with varying conditions and issues like hitting pot holes and gutters, deal with added load from having worn out factory caster rods etc. There may be changes as in version three model. They certainly will NOT be immune to ware or breaking. Appreciate the interest and feedback.
