Evening my Omega loving chums cold tonight

Oooook, as I've mentioned previously I am currently doing steering and suspension at the minute at school and we got told today that we've got to go to Corby Tresham to use their alignment machine.... it's a state of the art one (apparently) and as we don't have any money spent on the Wellingborough campus have one we are going over for a tutorial and a play 

The other great thing is they actually want us to put our own cars on it....free wheel alignment check off a dogs' bollerks machine

Now my car was last aligned by WIM and I know that the reason we take our cars over there is cos their research shows a different and better set up as opposed to the one the manufacturers recommend. SO. Below are the settings from the Haynes book of lies..... does anybody know what settings WIM use?

Front wheel alignment

Ps, I'm trying to find out the make and model of machine if anyone's interested

Thos figs are strait out of the factory book, and are good when the car is new on new springs, dampers, and bushes, give it year, and lots of pot holes and kerbs and thos figs can be chucked away.

LEGEND! Thanks Entwood. i'll print this out so I don't forget and see what we're at on the machine.

After asking my school buddies on Facebook it appears it's a Snap-on 3d 4 wheel aligner

Welcome .. edited the above to include the total/cross values as well

looking at the figures theres a noteable difference in camber at the front.

I "believe" from talking to him, that the main changes are to both front and rear camber to take account of the age of the suspension, which, being older and softer sits the car lower.

Can you take my car instead Webby as I've just replaced my wishbones and front struts so mine is probably shot to s*** now, despite my best efforts of taking measurements and marking the steering knuckle. 
Only kidding. Looks like a trip to WIM is on the cards. Shame mine had to be upset really as its always driven true and tyre wear was even across the band.  Wonder what my settings will be as my suspensions all new. 

Hope you have a good, informative day out.

cheers boys.

ill take photos and post up full details

Point to note our figures are without any ballast added since most places in the UK don't have ballast. In addition the castor position is adjustable by moving the subframe.

Fancy cutting your teeth on a 97 XJR Webby?

About to finish replacing shocks springs and bushes all round.  What a job that was!!

Thanks for confirming that... so no additional weight in the front or the boot?
