4link questions
Hey guys, im currently building up my mk2 escort, and was looking into 4link conversions so far i have put a BW 8.3/4" rear diff in it and am running koni yellow shocks and single leafs, i was looking into the 4link path after seeing a few kits, the big question i have is why when 4linking does everyone insist on putting turrets and long coil over style shocks in the rear end? the rear travel in an escort cannot be anywhere near the length of the coil over shock can it?

Rear turrets were designed for rally cars requiring a lot of travel.
Also the bottom shock mount is usually moved to the top of axle tube.

ok, so in theroy when doing a 4link conversion you could retain the bottom shock mount and use ladder bar style short coil over shocks instead of turreting and adding extra weight and work?

Link bars will be in the way of the original shock mount.

Having done a degree myself I can say Damion Parkin definitely deserves his degree after the work he's put in on that Escort setup dissertation.

I'm in the same boat as Matty. I have a Mk2 that Im thinking I should 4link. Cept mine is a 4 door.
I just have a few questions for the people in the know.
After reading the article posted above it seems that bars of the same length parallel and horizontal or a few degrees down is the most ideal set up for ... is this correct? or do i need to read it again.
Can i install turrets angled backwards a little bit so that the back part of the seat is able to fit?
Do i require a watts link?
And because im sure someone will ask the car has no engine at the moment it was going to have a pinto and then i wanted to change to a cosworth, but the project is taking so long cause im at uni im thinking that i should just skip the pinto. I would like to make 250-300rwhp.
I can make a new topic if you think its necessary.
Cheers

Jordy, you will need to run either a panhard rod or watts link when 4linking as you need to locate the diff left to right, when running a watts like with a 4 link it will be called a 4link, and this is the better option over a panhard rod as panhard will tend to allow side step under squat in one direction due to the ARC movement of the panhard bar.
Im currently study the above atricle and trying to come up with a way of not running turrets as i do not belive on a street/track driven car you need the shock length that was required in rally use.
Thanks for the info so far guys!!

Jordy, i spent a good hour on the phone today to mcdonald bros racing and am waiting to hear back form there but there is no reason why short shocks cannot be used providing correct mounting to save space and weight, im looking into their "street 4Link Kit" now and the floor pan will still need to be cut, and possibly some space into the boot floor to run short captive style shocks as opposed to a turreted coil over similar to a ladder bar setup, drop me a pm with your number and will have a chat if you want.

Let us know how it goes... saying that my parents said today how much longer is my car going to take, cause its in their garage, and I was like 'Well now i want to put other stuff (4link and a YB) in it that means getting rid of stuff that I've purchased ectect' Soooo long story short Its been decided that it will be finished with the parts I have so that's single leaf and a pinto and if I want to 4link and Cosworth it I need to wait till I have a job and my own place, might as well do another car AHHHH i have a small ford disease!.
Oh well when i finish uni and have a full time job I will have my whole pay check minus food and rent to spend on it =P
Anyways back on topic please keep this updated as It will be a great future reference.
