Im building a book locost, but am using sierra hubs. Does this mean i cant use the wishbones as shown in the book? If so, does any1 have plans for the mk type? Cheers

But, back to the question , I`d like to know this too. are the book wishbone dimensions suitable for sierra uprights, or put another way. are wishbones for sierra uprights suitable for cortina uprights, & no, buying them is not an option for me. Chheers, Steve.

The geometry of the upright is different and as such the lengths of the top bon changes. I also advise changing the offset of the top bone a little as well.

If you look at www.gtstuning.co.uk you'll find wishbones advertised on their that you can specify for either upright. For me Sierra is the way to go.

Kind regards,

Darren

as soon as you deviate from 'book' and / or dont use cortina hubs, you CANT use book wishbones.

There isnt a top joint taper - just a bloody great strut hole on the sierra. With an adapter its in a different place. I strongly suspect that the suspension pick up points on the chasiss will be a different height too.


why cant you buy bones? They are hard to make nice looking and it seems to be a hassle gettting the correct tubing too.

I live on the far side of the globe to most suppliers, I can access the correct tubing & can get them professionally welded after I tack them up. It would probably cost more to ship them to New Zealand than they cost.I`m also pigheaded enough to want to do as much as I can myself & mean enough to want to save those pennies for things I can`t make or have made locally such as shocks, headlights etc.
Now back to the original post & my hijacking of the thread, can anyone tell me how much longer or shorter for the same given length of bottom wishbone is a sierra top one compared to a cortina top one.By way of explanation, I`m trying to reverse engineer some wide track measurements I`ve been given from a sierra based car to a cortina based front. I`mm using a sierra back end. Thanks, Steve.

Think i'll just pay £110 quid and buy'em
So i hav to get
"Book Top Wishbone (GTS 551a)"
"Book Bottom Wishbone (GTS 552a)"
And thses will both fit my chassis and my sierra hubs ok?
See the 36 piece polybush seat, can these be used instead of tryin to make those shitty brackets in the book?
Thanx lads thats me happy now!

i made my bottom bone, twas crapp. bought the top and also bought the inner and outer tubes, the bushes and the brackets. Makes it easy to put together. Im gonna remake my bottom bones soon.
