I have a problem I think. I've mounted my front bones as per a drawing in James's file (cheers) and this I think is same as the book (I'd have to get off my arse to check but I'm sure it is!). I have GTS bones though, which I think may contribute to this. I've put me hub on (Sierra) and a disk because I was excited and its easier to see whats going on because it exagerrates it. My problem is that the top of my hub leans out from the car too much (negative camber?) even with the camber adjuster fully screwed up and no space for the locknut. I was wondering if its because the GTS upper bone is 10mm longer than the book and thus I should've mounted it lower? The bone as it is runs slightly upwards which I know is fine from looking at pictures but whats going on here can anyone help?

Cortina upright bottom wishbones are approx 30mm narrower per side when compared to Sierra upright wishbones, so if you use the Cortina (book) lower wishbones with Sierra uprights you would get a negative camber situation, which it would appear to be your problem

Hmm. A little confused here. I have GTS Locost top and bottom wishbones and Sierra hubs which I know work fine from seeing Gavs car. Not sure where Cortina uprights come into it though. Forgive my ignorance if I'm missing summat. I'll go and try and get a photo.

You can see from the rough verticals how much its squint and this has the adjuster screwed right up

Squint Caliper

As simply as possible:

Cortina uprights require shorter bottom wishbones than Sierra uprights (GTS make both).

The symptom your setup is showing (excessive positive camber) is what one would expect if the shorter Cortina type wishbones have been fitted to a Sierra upright.

Squint Caliper


Beaten to it !

No way! I bought them through Rally Design and they're just advertised as Locost wishbones. No mention of Cortina or Sierra. Immensly pi55ed off now. Wishbones weren't cheap to buy and neither are Cortina hubs so now I'm stuck in the brown stuff. Think I have a case to send them back?
Can anyone provide the lengths of the wishbones for the Sierra hubs just so's I can check?

To be fair the "Locost" book design uses Cortina uprights, so selling them as Locost wishbones doesn't seem underhand in any way.

Cheers Mark. Mine are no where near that.
The problem with Cortina uprights is that they ain't cheap and I'm absolutely skint (in the -ve numbers to be fair. Had no pay cheque since July!) ,they don't come around too often and I've already got Sierra front calipers and discs. I assume I'd have to buy Cortina calipers and discs if I swapped. Bah!

I would suggest that your cheapest route would be to get another set of bottom wishbones, suitable for the Sierra uprights. You may be able to swap them with the original suplier, if they do the Sierra type. Alternatively make up a set yourself, you have all the dimentions, just need to be 30mm longer. Regards, Ray

If you use wider bottom wishbones you will need some track rod extensions with the Escort rack if you are using it.

Yep I have these already sorted too. Another reason as to why I'm gonna stick with the Sierra thing for now. I'm just too skint to fork out for stuff again when I can just stick with what I've got for the now and think about it later. I'd just like to push on with things, I'm so impatient but the money thing keeps holding me back. Bah

Unlucky mate, i did say tripple check everything before you buy, i would of saved myself a fortune if i had!

The reason why you couldnt post the pic is that the server wont allow you to post dynamic images, ie the ones that come via php script,
its got to be an absolute URL to the image.

I suppose it's just one of them things in a very expensive hobby. They just seem to happen when you're skint, almost at a milestone or when there was a replacement on Ebay that was really cheap but ended last night and they don't come round that often. But, all part of the learning I suppose and it wouldn't be interesting if it all went right first time.
