Angle of front hub all wrong
Hi,
I am a little troubled by the angle that the hub sits at now that I have completed the front wishbone / suspension stage of my build. It looks like
the wheel will be about 25 degrees off vertical when the car is sat on the ground. Can anybody think of a reason for this as I can't see
anything wrong with what I have done?
Cheers
Steve

It looks like the wishbones are for cortina uprights and you have sierra uprights to me although i could be comletely wrong.

It looks like the hub is upside down
and offside/nearside hubs are swapped.
What do you think?

The lower wishbone should be paralell to the floor when the weights all on not angled down like they are in the pic.. Try disconnecting the shock and
hold it level and see what its like then.
Being a velocity its made for sierra uprights so unless theyv given u the wrong bones theres not much else to be wrong.

Steve,
The upright is the right way up and is facing the right way - I would second what Andy said - looks like you have long top 'bones which would
suit the geometry of the cortina upright rather than the sierra one.
Is the Luego kit based around the cortina upright and were the wishbones part of the kit?
I guess you could swap them for sierra upright compatible ones?

The suspension will probably never see that much droop once the car is finished.
Usually ride height is set up with the lower wishbones level to the ground.
(The range of movement is then probably no more than 1.5/2 inches in bump and something similar in droop.)
With the suspension raised to this height does the hub angle look better?

Beat me to it Dan! I thought the luego was a sierra based kit...
I was wondering whether the upright would pull more vertical with lower bones parallel to the floor too - but it does seem a way off...
Enlighten us Steve!

The only other thing that occured to me just now is that your lower bones look a little short for a sierra track locost....
Where are they from?

Definately the wrong top wishbone, that is for the cortina upright, the U/J comes straight out and not pointing slightly upwards as it should. If you
raise the whole lot it would just get worse, as the top rises with it and that is shorter. Need to get on to your kit maker for the correct top
bones.

I haven't had a moment to take the shock off and try it but I don't think it will make much difference, I will though over Christmas. The
wishbones came from Luego and it is a Sierra based kit so that is all correct. I'll talk to them again.
Thanks

Like everyone has spotted mixture of Cortina and Sierra bits -- but I am not convinced it is the top that is wrong suspect it might be the bottom.
Not too keen on design of bottom wishbone anyway --

According to 'Des Hammill Suspension & Brakes' book, in droop like you in your photo steve, a typical double wishbone suspension
should give excessive negative camber. In your case though you've got excessive positive camber so something is definatively not right.
Even with a cortina upright you would still be getting positiove caber.
