I didnt have any offs on sunday, except dropping 2 wheels but it was on the passenger side and very soft. I have several offs but none are hard. This was at buttonwillow so we ride the berms pretty hard or "hop" them.... I was running 2:02's in cw13 configuration

I bent a rear one at carolina motorsports park when I went hard sideways against some agressive gator, but snapping one is pretty extreme. I had a "large" friend of mine sit/bounce on the back of the car to bend it enough to drive it back on the trailer

Are you running coilovers in the rear?
Drop me a pm

Did you have SPC rear arm? Mine snapped too. I see the defect with them if this was SPC. Worried if this was SPL.

SPC threads arm first and then bends the arm. The threads in place where arm bends are fatigued and allows arm to sheer off. If your arm was SPC then I think it's an arm design if not I will be wanting to see arm and type of breakage. Very interested to see that happened? Was it at threaded section. Did you have threaded section lock nut way out towards the end?

Shamu, I still didnt get a chance to tear it apart, but it was right by the thread/lock nut. I should have pics this weekend.

We have a couple sets ready at the shop for those that are interested.

martin whats the deal? guna fill us in on the broken parts?

Broken SPC rear camber arm. Broke on the threaded part before the jam nut. He just posted on FB last week. Things of this nature happen. He upgraded to the SPL arms which are beefier. Still I feel there is nothing wrong with SPC products. When you track a car things happen in time.

Things happen...I can see that after contact.. Or an off track excursion ...and go backwards over curbing.
But if a part fails under load...without these other circumstances... There is only one answer...it's not engineered properly.

Just saying.

thx for the clarification, im not a facebook-er so i didnt see which ones and how they broke.

I will have a full post coming up in a few days with pics etc. I'd love to buy the doran arms but I have no more mod $$$ !

i might be at barber in a couple weeks :stirthepot:

In a couple...or next??? Cause we arrive there Tuesday night ;) test day Wednesday.

yea next weekend... haven't heard anything back tho after i replied :(

To which?

still no reply... doesn't look like it's gonna happen :(

Ok I've lost track of where we're at on these parts, the thread's getting long. What's the availability/price at for the various pieces discussed? I really need some front upper arms soon. The outer edges of my front tires are getting shredded fast now at unadjustable stock camber as I get the rest of the suspension stiffer and get through the corners faster.

Should be another member posting on here shortly regarding our upper control arms.
All our parts can be made available... And if anyone is for sure serious ...you could always bring your Z to the shop an have the boys work on your project.
The one thing to remember ...our parts are not aftermarket per say... but what we consider race components. This brings tighter tolerances/specs as they need to withstand the environment and punishment we put them through...but it also brings a higher cost to manufacture and price tag.

would be a lot easier to pull the trigger if we had more pictures, specs, etc... just not enough info for me, unfortunately

What specs and info are you looking for exactly? There are something's we won't post pictures of...sorry just they way it is.

*Some things

I got sick of the crappy SPC control arms so I made the leap. Expensive but if you do a lot of track miles, probably worth it. Couple of teaser pics. I'll have a full track review on Wednesday after I get back from Summit Point.

I think you successfully put some heat in those rotors :)

Mostly: What's the camber adjust range, what the price, and what's the lead time to get a pair?

Well, there were some other questions, but the pic above answers some of that.

Beauteous!

Looks like I'm not the only one to have these now. Just wondering what shims you ended up using and what is your camber setting?

Do you have a link to this?

how long have you been running SPC front arms, and your experiences with them?

Thanks!

I would love to buy the Doran Arms as they look amazing and no doubt they will perform, just have some other updates at the moment.

Here is the SPL vs SPC and you can see where it broke. The 2nd picture you can see even the bushings are completely shot, and I am dead sure the front control arms are shot too. This happened while on track doing about 80-90mph at Buttonwillow, now my rear knuckle stock bushings are tearing. I called SPC they said they would send me a brand new replacement a few months ago but they never did. Corner3 Garage came through with SPL rear camber arm on the spot! (Thanks Mike w/ Corner3). I had to tow the car about 200+ miles

Edit: This happened about 15 track days? Upon removal, it messed up my rear knuckle bushings due to the wheel extending out and towed inwards excessively , this could have been a bad wreck. I ordered ALL SPL bushings all around....

SPC is JUNK

proven...

:eek: :eek: That sh*t is craZZZZZZZZZZZy!!!!!!! :eek: :eek:

Here are some additional pics!

Also, my cv joint is clicking now!!!!!

:(

What's the pricing for Doran Racing arms?

now looking into an SPL rear kit as well after all this craziness popping up...

I would love to know as well, but i'm not too sure if they're in mass production or even available to the general public

They are available, but supply is limited.

Now you're on trend with the latest craze in the Japan custom car scene. :ugh2:

Yes available to general public.

Sub'd for when I buy coilovers

Lets not see anyone else have to go through this....Those last images of the Z on the flat bed made me almost tear up...:facepalm:
