Powerflex camber bolt issue

[1985michael182]

Ok so fitted the bolts and had it tracked up with 1.5° of neg camber. On track under hard cornering they jumped out of camber and had to go back the the pits to see what the problem was. No matter how tight I made them they still slipped out of camber. Has anybody else experienced this and am I doing something wrong or are the powerflex bolts just for show and shine and not for track use?
Next stop cadwell 2nd August so need some answers. Thanks guys

Can't say I've heard of this issue on here. Allways used eibach and never had an issue

 

[JamesBryan]

What were you torquing them to?

 

[1985michael182]

I tightened them FT after they slipped but felt like they would snap at any minute so jibbed out.

 

[1985michael182]

Think ill buy some 14mm eibach ones. They look like they are high tensile steel instead of the powerflex electroplated ones which are probably just mild steel

 

[bloke]

never had problems with the powerflex ones.

is the tag on the washer sitting in the hole on the damper ok?

 

[1985michael182]

I'll have a check at the weekend just ordered a gunsen camber tool so can check and change camber at the track I'll have ago and hit some corners hard See what happens

 

[1985michael182]

Are there any solid top mounts that have camber adjustment ?

Are there any solid top mounts that have camber adjustment ?

Yes ast do some - orange looking.
Camber / castor adjustment is achievable

Compbrake I think do a similar mount , not sure it achieves the same results

 

[1985michael182]

I'll try see if I can find some. I have ordered the eibach bolts anyway 14mm see if there are any better just to get me back out

I bought powerflex bolts about a year ago and fitted them last week, had wheels aligned, then needed to take them off to change strut top mounts. While putting one side back on the nut stripped. Only used torque wrench at 120 Nm. Have had to pull them out ang get alignment redone. Not happy.

They definitely shouldn't be moving on track, I use the kerbs a lot and never had an issue.

 

[1985michael182]

Ok use kerbs aswell and they were fine there just high speed corners they jumped. Was a croft when they did it thought I had snapped a ball joint to start with as it was at full positive camber and steering was al over the place!
That nut shouldn't have stripped. Is 120nm the correct setting?

 

[JamesBryan]

Sounds a bit high.

Eibach bolts are torqued to 105nm iirc.

 

[1985michael182]

That's good to know. I'll use that setting when they turn up.
Bought a Gunsen camber setter aswell so if I do need to reset cambers in the pits I will have a decent reading

 

[1985michael182]

So I found the problem....

 

[1985michael182]

Tried to upload the picture but I don't know how to do it. Powerflex bolts were 12mm on the cam lobe bit and eibach ones are 14mm on the cam lobe bit thus explaining why they were slipping under high load. Im surprised they didn't snap to be honest!!!

 

[1985michael182]

Oh..... the pictures there???

 

[JamesBryan]

Yep i've seen that before.

@Niall had a set which were marked for use on a 172/182, i spotted that they were 12mm and warned him to get eibachs instead.

 

[1985michael182]

Yea crap that from powerflex! Oh well these will work now good now and I'll be able to push it

 

[JamesBryan]

My Eibachs haven't moved in 2 years :up:

 

[Niall]

Yeah I've gone with Eibachs as James says, just the tried and trusted ones and for the same price you'd be silly not to.

 

[colesy]

I'm worried I've got the wrong ones in mine now as I just bought some power flex ones. Think I'll swap them out for eibach ones before I venture onto track.

 

[simonmac]

Pretty sure 120nm is way too high for camber bolts, can't remember exact settings, though around 65-70nm might be right.

 

[JamesBryan]

Just fitted some to a Clio tonight.

132nm the box says.
