Hi
It does need to be shortended, both the front wheels look like as if they are toeing out at angle of 20 degree.!!!!!!!!!!
Yes hope we get some clarification on this from some kind members!!

Hi Andy
I think we are getting somewhere, yes you are right without modification the car will be undriveable. Could you please tell me what is the totall lenght of the rack either with or without the extentsion.

hang on a mo, i,ll go and measure my rack / extensions for you, 2 tics

andy

here goes....

total length between the center of the threads of the track rod ends is

135 cm

this includes the rack.... rack extensions & track rod ends....

the actual length of the rack extensions on their own is 13 cm.

sorry i can,t give the measurement of each individual part but its all put together on my car, so taking into account some final adjustment of tracking, the figure of 135 cm is about right....

as said it is a std escort mkII rack with the 13cm rack extensions fitted then connected to the track rod ends........hope that makes sense:o :)

if i may say.... i think folk are getting confused when talking about shortening the rack as i think this is meant to imply the SIERRA donor,s rack when mentioned in the book......use the escort rack & you,ll be fine, but don,t make the extensions to the spec as stated in the book.

hope this helps.

cheers

Hi Andy
This is great, I am sure i will be able to sort something now.
Thanks 10000000000000000000000000............

One thing still a mistery I am using the escort rack, the suspension still in the air could this be the reason???????????

no prob.
hope my above post made some sense :o :confused: :D

Axle.... are you using extensions made from the book dimensions? if so they are too long, with the escort rack the extensions only need to be 13cm in length

cheers
andy

oops...

just read the whole thread again...

Axle... the rack extensions supplied by MK are to the book spec which makes them too long ;)

either shorten them to 13 cm or buy extensions from Rally design & you,ll be sorted.

the extensions shown in the book on page 76 diagram 5.36 is incorrect.
the main body of the extension needs to be 13cm .

cheers
andy

I think you will find,

The reason Chris has mentioned the shortening of the rack is so that the inner ball joint is in line with the suspension pivots. thus ensuring a constant distnace between the rack ball and the steering arm. This will negate any Bump steer. The slight difference will creatr a bit of bump but may be acceptable to the IVA.


Thats my take on it anyway.

You would not shorten the rack because your extensions were too long.

Quote From book.

Athough the ESCORT steering rack is very close to the ideal.........

In fact look at diagram 5.34 p 75

It shows the ball in line with the pivots with 533mm between ball joint centers.

:D
