Using sierra hubs
I have just bought a chassis and a box of bits for £80 and there are some sierra hubs in the box. Being a total newcomer can someone tell me if I can
use the top wishbones from the book or will they need to be a different length to keep the camber angle right? Any help would be greatly appreciated

AFAIK the wishbones will be the same (someone please correct me if I'm wrong because it will effect my chassis aswell!!)
You will need some adaptors to allow you to fit the wishbones as the Sierra has McPh struts. Dunc can sort you out with those on the cheap!

Hey Chaps,
I can send you guys a couple of sketches showing the relative positions of the centres of the upper and lower balljoints when using the sierra hubs
and the relationship to the trackrod end ball joint and tyre centre line. I'm no expert on suspension design but I've written a Excel spreadsheet to
work out camber and track changes during roll and bump. It needs a lot of tidying to understand it. Hopefully you could use the info to help you
decide wether to use the books wishbones. Also, the book uses Cortina bottom wishbones but these wont fit into the Sierra hub without major mods, I'm
using Maxi ball joints so a different patterned plate is required, basically it's 3 holes. Chris, how about I email the jpgs or dxfs I've got of
these parts for the members.
Dunc.

Email them over mate! Anything for the site is greatfully recieved although I'm not sure what software I need for these .dxf files. (JPG is fine
though). I keep meaning to scan in those diagrams you sent me with the brackets... perhaps at the weekend!

Chris,
Paint shop pro or similar can read dxfs no problem. I sort them out and email them to you.

Photoshop should open the dxf format too, dxf is the autocad format so try open then select the file types to see if it's available as an import
style.

If you are going to meet up with us at kempton park this saturday,you can have a peep at my sierra hubs and top balljoint inserts.
Mine are from MK and came with chassis deal,the balljoint hole is off centre so as the insert can be turned.
