Hi,
I have decided to build a chassis 4" wider to give more room in the cockpit for seats etc..
I am using standard book suspension set up and want to know which rear axle and diff would be best suited?
Cortina? Capri? others?

Steve, I'm using a mk 3 cortina axle in my +4" chassis with book suspension, seems ok to me.

Yep I've used a Mk4 cortina axle in my +4" wide car, I belive the Capri axle is good too.

Cheers

Chris

looks like I will have to contact an old work mate who had a cortina axle gathering dust from an abandoned kit project.

Does anyone know what sort of diff ratio's they have, are the comparable to the escort?

Steve,

If you fancy a nightmare, I'm using Sierra Diff / shafts, fabricated upright adaptors and homemade wishbones.

Yeah I though about going down the irs route, the thing is I already have four trailing arms and 2 diff brackets ready to weld on.
The other thing is I am not sure about wishbone lengths etc.. suspension geometry is very important and I am not clever enough to work it out!!
If I had a set of plans however and I might reconsider. I am sure I can make some upright adaptors, I had a good look at a MK indy!
The drive shafts I could shorten if neccessary as I have access to a lathe.

where abouts in northants are you, out of interest. Im in kettering anf Paulf is just outside it.

Kettering? That's only 30 miles form me in Bedford! I'll have to come and have a gander some time.

You'll like that won't you.

My son lives in Wollaston, Northants.....not a million miles away. Possibly meet up some time when I'm over visiting?

Cheers,

I live in Irthlingborough. But most of my locost bits are still in Barton Seagrave clogging up my Mum's garage whilst I finish building my own garage.
