caterham wishbones
i have tried a search but can't find anything - does anyone know how easy it is to fit standard caterham wishbones to a standard book chassis -
are the mounting points in approx the same place or would it take a bit of modification?
cheers
if you don't fail, you aren't trying hard enough.

The caterham is a totally different car!
There is no relation between them and a locost, as such the wishbones are not interchangable..

Looks like the front mount is in single shear in front of the chassis section. Picture borrowed fron R500 site.

yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I'm not sure how similar the wesfield wishbones are to a caterham, but I made a set of westfield wishbones fit on my locost. The only
modification That I am making is to elongate the lower arms about 1 1/2 inch.

How?
How did you determine that the wishbones needed to be 1.5" longer?

Once I got the upper arms in place, I made a sleeve that I could extend the wishbones in, and with my high speed level and laser level got to the
point where the rotors would basically keep the same camber, +/- .5 degree.
I think it was alot of trial and error, and even more dumb luck. Total process took me 4 weeks, about 65 hours to do for just the passenger side, the
drivers side only took me 15 minutes.

derf,
You should have done the drivers side first!

Yeh, I wish I would have though of that, If I would have done the drivers side first and it only took me 15 minutes, think about how fast I could have
dont the passenger side!!!!
Yeh let the little happy face smile, see if you'll be smiling afer I introduce you to my friend Mr. Louisville Slugger

Perhaps you should have asked Mr Slugger for some help earlier.
Don't like the smile? Try this then

If you set the suspension up so there is no change in camber during bump, then aren't you going to get positive camber during during roll on the
compressed side?

No because when I set the suspension it is pre set with camber, so when the car rolls, and the camber changes it goes to around 0. The camber should
be set at between 3-5 degrees.

lower A arm extension
 
front suspension complete
Oh yeh, here is the final modified westfield lower A arms, The thiner walled tube from the westfield A arms are still almost the entire length of the
extension (thicker tube), there is only a small 1.5 inch area in the center that is where I cut.

front alignment
where are you going here, do you know anything about roll center or the relationship between the (upper and lower inboard ends) and the (upper and
lower out board ends) of the wishbones, here is the only place you can alter the camber during suspension travel.
moving the upper balljoint backward or forward has an effect on toe as you turn, as a rule of thumb, if you project a line from the center of the top
balljoint to the center of the bottom balljoint and then project a line from that through the trackrod end to the rear axle, the left and right side
lines must converge at the center of the rear axle on its axial and lateral centerline, now when you turn the steering, this intersection should
travel allong the rear axle, when you turn right this intersection should travel to the left and visa versa
