Very big job and, IMO, not worth it to make setting up a bit faster.

There was a Rover V8 engined Chevette a few years back that had been converted, but not the nicest looking conversion done to be honest. My mate keeps trying to get me to do it, but it's alright for him as he built his own independent double wishbone rear end for his Escort MK2 . I have thought about a coil over conversion like some of the Opel Kadett C's in Germany (hill climb ones). I'll see if I can find some pictures.

I would only suggest doing this type of conversion with a proper welded in cage and cage pointed to shock mounts as standard inner wings will not take the punishment , not sure this conversion would be like on a road car as this car is a German hill climber. To be honest I would do a bit more research on the German Kadett forums if I was you.

Why on earth would anyone want to take a backward step with their suspension!!!!????!!!???!?!?!?!!?
The Chevette double wishbone suspension is far superior to the Escort MacPherson strut and the shell isnt designed to take the loading of such an item.
I have owned both vehicles and the Chevette outhandles the Escort hands down.
IMO it is a waste of time and money to convert. If anything I would make tubular wishbones, using rose joints, to replace the originals and to allow easier adjustment of the suspension geometry.

Rant over!

Wouldn't you say it is easier to change springs with the escort compared to the Chevette? and most people have loads of 2 1/4 springs kicking around and cheaper to replace.

Yes it is easier to change a spring on a Mk2 (although when you have uprated/shorter springs on a chevette they are quite easy to change) but which would you prefer, a car that handles mint, or a car thats easy to change the springs on?
If its a competition car and your running different springs for loose and tarmac you may have to change them once a month, but if its a trackday/road car you will just fit them the once.
Yes 2.25 coilover springs are readily available for about £35 pr (new) but that is minimal after the cost of converting the front end of a chevette to run struts.
TJM does front springs to your spec for not a great deal of money, that is a far cheaper option and keeps the suspension working as it was designed.
P.S. by the way , a common upgrade on the Mk2 is to create a lower wishbone effect by fitting compression struts between the track control arm and shell!! so who got it right?

TBH, if I was expecting to be changing between a Tarmac and Gravel spec front end, I would probably have the engine chassis mounted and have two front ends made up - should be easier to swap subframes* if you have things set up right.

*Trailing wishbone bolts (2), crossmember mounting bolts (4), steering column (1), brake hoses (2) and rebleed and damper top mounts (2).
Oh, and wheels, of course!

I did just that, mounted the engine to the chassis rails so I could drop the front end easily.

Race cars really should have adjustable suspension all round so that you can not only set the ride height but set up the weight distribution too (not like a road car for looks). I do know where your coming from though, I too have had a couple of mk2's.
If you look on the picture of the Nolte Motorsport Kadett C it has adjustable coil overs rather than MacPherson struts. It's not a lot of cost really if you can do the work your self or have a mate that can do it, some people like a challenge. I have a mate of mine with a MK2 Escort and he wasn't happy with it's handling over the bumpy stuff, he had already 5 linked it then went on to build his own double wishbone set up on the back end all built from scratch using a Sierra 7.5" diff which Has now evolved with using a BMW E90 M3 diff, he said if you got stuck in you could have the inner wings pointed to the cage and chassis rails with a strut brace all done in a weekend.

I like the swapping of the cross member from tarmac to forest spec idea.
