R32 Gtr Upper Camber Arms?

[boostd_r32_gurl]

Basically I have installed a set of "dog bone" upper camber arms and I can not get more then +1 camber on the front!! I could get -2 camber using the whiteline bushes/standard arms.....the wierd thing is that the hole to hole measurement is 10mm shorter on the dog bone arms (165mm) so in theory they should be giving better camber then -2...not +1.....?????

the camber arms are designed for when your car is really low and you have way too much negative camber...

[boostd_r32_gurl]

I'am stating that the shorter the arm used the more negative camber, the question is why is an arm 10mm shorter then the standard arm giving less camber instead of more??

It may be because the dog bones don't have the same offset as the stockers between the inner and the outer

You can install them in various ways and it effects both camber and caster. If you have them offset towards the front it may explain your problem (you also lose caster). If you have them even you will gain caster and it should increase your negative camber. I did in my GTSt, also going from an adjustable bush type to a dogbone.

I'm kinda guessing but it's about the only thing it could be really, short of a dud tape measure or your existing bushes having enough compliance that the geometry changes when loaded.

Yeah I ofsetted them to the exact shape/measurement as the standard arm so the dog bone was basically identical...might try to install them another way and see if that works....running out of idea's as its going for an alignment Friday.

who is measuring the camber? sometimes the problem is in the alignment gear.

also, have you adjusted castor since you had the -2 with the bushes? with the arms being 10mm shorter than the old -2 set-up with the offet bushes you obviously should have more neg not less.

has the height of the car changed since you had the -2 with the bushes? that will affect the camber too of course.

All sussed, had a play around today and although the arms were ofsetted correctly, the right hand side arm had been installed in the left hand side and vice versa......simple mistake....very annoying. Thanks for everyones help especially "badhairdave" who seemed to be right on the money. Looks to be around -3/-4 at about 355mm eyebrow height but will soon find out tomorrow at the aligner.

I'm betting that they put them on the wrong way around!

It's hard to describe, but the arms are an "H" shape. When installed correctly, the H shape should not symetrical. If they are installed incorrectly, the change in body length due to the adhustment doesn't pull at right angles to the direction of camber.

Anyway - take your wheel off and post a picture and I'll tell you if they are installed properly :-)

Hi Gav, problem has been sorted. Explanation is right above your post^^^
