i bought a egay camber kit. then went to kingbolt in covina CA and wanted to beef up the hardware. the allen head hardware was stamped 12.9 strength. it was nickle plated which he said was weird. have gave me 10.9 strength hardware to use. i ask why a lower strength? he said really high strength stuff doesnt give or bend and when it gives it snaps. 10.9 will do that. sounds logical. he said i would be suprised on what strength bolts they use to build large buildings.

thanks for that insightful post.

Now I can sleep at night, knowing you have the right hardware for the yob.

 

What was wrong with the 12.9 screws in the first place?
You didn't need to change them out - the Kingbolt guy played you.

 

I didnt trust those bolts either, but I went a step further.

I got these - Metric Flange-Head Class 12.9 Alloy Steel M6x20mm
Part Number 92235A240 @ http://www.mcmaster.com/#
$4 for 10 of them.

The tensile and shear strength of the bolts isnt the only thing you need to worry about with adjustable camber arms. I have seen the top of the arm, the plate that the bolt heads sit on, get torn through right where the bolt head was. The bolts were still fine. So you not only need good bolts, you need to spread out the load with a larger surface area. But because the EF arms usually have the raised section in the top-center of the arm, regular washers wont fit. The washers attached to these ^^^ bolts just barely fit. And they add enough surface area to at least give me some more peace of mind.

 

well i didnt buy these camber control arms so i could put them to the test. my d15b2 is never going to see redline or a moutain road. i bought them so when i get the alignment the camber is adjustable. thats all. i went to kingbolt for the comfort of knowing the bolts i was using was the strength it was stamped with.
i had no faith in the bolts it came with. i feel i brought the camber kit from an egay quality to an ebay quality.

 

Front control arm camber kit?? The bolts would be the last thing I would be worried about.

 

meeaning?

 

Ball joints are ****...

 

i was thinking the same thing

do you think i should buy some from autozone and press them in ?

throwing away the old ones

 

Good luck pressing ball joints in and out of your UCA's. Its damn near impossible without bending the crap out of them.

 

well camber kit so. i can get the ball joint away from the control arm itself. and then a 5 ton press. what do you think.

 

I think you're going to bend the **** out of your UCA like myself and many others have done. Your only real option unless you're a wizard is to get an entire adjustable UCA. Ebay camber kits are junk and I think its mighty ignorant that you're trusting your life to one and of all the drivers around you.

 

...that is what he has...

 

and like i said in a post before. i bought the camber kit not for performance but merely to have camber adjustable when i go and get a alignment.

 

Are you referring to the stock UCA?

 

CMON BRO!
