Mk3 Cortina, back axle, steering and front hubs?
Hi,
I was hoping that I could get a definate answer on this, as I have been a little confused by some other posts and websites I have found.
I have now got my garage space and equipment I need to start looking for a donor for my project.
I would really prefer to use a Mk3 Cortina rear axle as I prefer the width and I know of a donor car.
However, I would also like the front track to be the same as the rear, so has there ever been a set of plans to make a wider front suspension/wishbone
setup to accommodate the extra width of the track and steering rack.
I would like to keep the chassis the same width as the book, rather than moving to the wider design.
So, ideally I would like:
-Standard-width chassis
-Mk3 Cortina rear axle
-Mk3 Cortina front hub assemblies
-Mk3 Cortina steering rack
-Front track same width as rear.
Has this been done, and more importantly, when properly set-up would there be any handling issues that would make the traditional book design
preferable?
Many Many thanks for any help.

Can I ask why? My front is narrower than my rear and it has never worried/bothered me - is there something you are not telling us?

Loads of companies now sell wide track kits...
... but mostly for Caterham and Westfield unfortunately. Quite a few Westfields are wider at the rear than the front, and many people are switching
to 'wide-track' front suspension.
Kits are made by Caterham & Westfield themselves, Freestyle, SBD, CAT Motorsport, Caged, and others.
If someone had the dimensions of an original set of bones and the required extra, they could make a set fairly easily.
I would have thought that someone like MNR, MK, GTS, etc could knock some up pretty easily.
The main reason I believe is for better turn-in & grip. Not sure of the technicalities, but I'd think someone on the site would be!
HTH,
Adam.

Yes, the Cortina axle weighs a metric shitload, and it's all unsprung weright so getting a good compromise on the spring and dampers rates is
difficult. The English axle ia a featherweight by comparison.
If you like the wide rear axle on standard width chassis look (personaly I don't) then why not consider using either a De-dion axle or IRS with
a Sierra drivetrain? This will give you is pretty much the same width as a Cortina, without the unsprung weight penalty and with the possibility of a
reasonably priced LSD if you should need it.
