Has anyone that brought the UAS front camber arms had this problem yet? put the zed on the hoist this morning to put the manual gearbox in. had a look at the camber arms and they are bent like a banana. pretty pissed off, seeing as they haven't even done 6000kms yet. with no track time and i don't drift because i don't know how to. so post up if you got some problems with yours. here is the original thread bout these. http://www.aus300zx.com/forum/showthread.php?t=288476 be the last part that i buy off of UAS.
have you spoke to UAS? IT would be good if we could keep this thread on point and free of slander(not directing that at any posts so far) I am not a fan of any of the aftermarket front camber arms, All of them i have seen have some flaw. The bearings dont last, they crack,bent,split, cheap poly bushes fail and some of them just rely of the clamping foce of small bolts to hold the adjustment. That is just poxy. In my opinion the only way to stay safe is with OEM arms and to space them out off the body. I think UAs and alot of suppliers of these types of components cover themselves by listing them as for off road use only so i dont think you are legally entitled to a refund or exchange. Im sure UAS will come to the party though but in my opinion id be getting a refund and going back to OEM whenre failure rates are zero
I have sent a pm to rob260 because he ran the GB. asking him for advice on who to go to. and i need the aftermarket ones to get the right camber on the rims.
n power/powertrix , so many copies and names, i dont know who the originals are. the bearings dont last long though....
There is NOTHING wrong with the arms. Its the application. I will bet $50 that you still have rubber/plastic bushed Tension rods. YOU CANT USED ANY BEARING ARMS ( including Midori style) WITH RUBBER BUSHED TENSION RODS. That is what happens. Think about it, The arms can twist and they can go up and down. What happens if the wheel moves backward under impact ?? It bends the least strong part of the rod just like your pic. You can ONLY use bearing upper arms wiith ROSE jointed tension rods which totally limit fore and aft movment of the assembly. JP agreed with me and AFAIK there was going to be something in the instructions to point this out. The only suitable adjustable upper arm that allow you to use rubber tenson rods are the Stillen ones with Rubber/plastic inserts. Send those ones back to JP to be repaired, buy some good rose jointed tension rods and get on with life.
Dinoz reported this problem not long after Warrick Nationals(mine went about 6 months ago). JP is having re-designed and engineered replacements made at the moment. The threaded "neck" section on one end needs to be longer in some applications, so that there is much less exposed thread on the center pivot. I suggest you contact him, direct. BTW, I have been running rose-jointed Tension Rods for many years(it did not stop this from occurring).
So your's bent as well Lloyd ?? In Dino's case. He had swapped these out prior to the last track day at Phillip island. He was telling me about them and as he adjusted the upper arms to increase camber for the track I could see his Midori arms where in fact bent as well. There is only one explaination. NONE of these bearing arms can accommodate fore and aft movment. Even with rose jointed rods as the wheel goes up and down the wish bone still mmoves fore and aft but much less than if the rods where rubber bushed. Here are Stillens
Yep! I'm inclined to think you're correct. Don't forget that these items were designed and manufactured in consultation with one of the best racing engineers in this country. I think that there is room for some more fine tuning of the design(and this is happening as we speak). The Midori style arms are no solution to the problem, as I have discovered on several occasions(although some are better than others). I am currently using the red & silver type, pictured earlier in this thread(whilst I wait to see what comes from the re-design of the UAS item).
So what's the solution then? Nolathane/urathane bushings throughout? These arms should hold up to road use with inspection intervals observed, and race use. Furthermore, the identified failure rate of this product on this forum alone is significant (ie of concern, but not necessarily unacceptable - playing it safe with that comment). How this relates to stock, midori, or stillen styles arms is outside of my knowledge, therefore I cannot comment on this in a comparative capacity. This thread is of interest to me, as I am undertaking a full suspension overhaul in the future.
STAY ON TRACK PEOPLE. i want people to post up what has happened to theirs. i don't want any bitch fights on this thread. if you want to have a bitch fight. go start your own thread.
with respect though Lloyd, racing and street use are very different, no kerbs gutters or potholes on the track. Or at least id hope there isnt!! Are these advertised for street or race use?
thats what i was going to say, everyone is on topic Good points raised about the tension rods there G
JP actually made 2 versions of these. The race version was the same but the centre threaded part was shorter because of the extra camber requirement of Semislicks. I should point out My road car still has all nolathane Stillen camber arms and tension rods. Never had a problem. Didnt ever like Midori arms
