Cortina Diff

Postby Jakes777 on Wed Oct 09, 2013 9:28 am

I've been looking though the forum for my answer, but can't get anything on using the Cortina Mk 5 diff for a locost build. And will i be able to widen the frame by 100mm if i use this diff?

There's no reason why you should'nt be able to use this diff , anything is possible with the application of the mind.
Bearing in mind it also depends on what you intend to do with your car , you need to be selective about ratio's.
Have you looked at this site ? There are plans for extended as well as std "Locost" builds.

Having said that, any deviation from std means that sourcing things like a scuttle and nosecone become problematic unless you hook up with someone who has already built a widebody such as the 442 - 4" wider, 4" longer, 2" higher - 4" being 100mm of course.

I think Wynand has done the 442 and might be able to help in the Scuttle and nosecone dept.

Thanx for the link! I will be building the +400, as I'm going to run the 20v motor. The +4 works perfect for the cortina stearing rack as its 4" longer than the escort rack. :D
