Midi Chassis?
I'm thinking and yearning for a midi.. really fancy knocking one up meself.
So, I think modding a locost or haynes chassis is a starting point.
I want Cortina geometry on the front as I like the alli uprights Rally Design sell.. I also like the deep dish wheels that where once on rwd
Fords...
Question is, which book should I start with? Chris Gibbs or Ron Champions.. All I need is the basic frame layout with front end geometry, I'll
be modding the rest as I go along.

Coozer.
Having had the privilege of being involved in two blank build table scratch build mid engined cars, I would not start with a front engined chassis.
Other than a wheel on each corner, there really is not much else in common.
Bearing in mind that a locost chassis imposes certain presets upon you, you can only ever end up with a car which is a compromise.
By having a mid engine, the position of the driver relative to the wheelbase is vastly different between mid and front engined cars.
The packaging of other components is also vastly different.
The architecture of a locost chassis is utterly unsuited to having an engine in the back, and is equally unsuited to suitable packaging of the
driver.
If you must use the Cortina bits, fair enough, equally so the deep dish wheels. That's what the car in my current avatar is now sitting on.
10" wide revolutions on the back.
What would be your choice of powertrain ?

My choice of powertrain just now is Fiesta 1.4 zetec... then a 1.6 turbo.
Do you have any plans off any of your midi's?
Was only really thinking of the front end of the locost chassis for suspension/steering set up and maybe ease of using the nose cone. Then basic rear
bulkhead size and angle. Everything else in between to suit a midi layout and my frame

You can do it quickly. You can do it cheap. You can do it right. – Pick any two.

I can only echo what that other thread says.
Ergonomics are obviously very important.
We're in the middle of mocking up a project right now and what you might think work with regard to what your size / shape is is really worth
considering at the outset. It's your chance to make it work. What works for me as a 6'2" bloke and a 5'something person are
quite different.
Clean the garage out, get the engine, box, shafts into place and start imagining.
I'll see if I can dig out some more pics of the car to the left.
It's just about finished and don't want to give too much of the game away right now.

Hi,
I used both books and have ended up quite far away from either with my design. 2 years on I am finally ready to start cutting steel. I actually used
the mojo as inspiration when I designed my car, if you want any advice on what I've done give me a shout.
Happy to share my limited experience.
