Hi Chaz, my car does exactly the same as yours. Worst car i have ever driven. Found this post by snoopy but not tried it yet.
basic setup
tracking 0-1degree toe out
camber 1 degree in all round
caster mushroom inserts offset hole to front
tyre pressures 17 -18 p.s.i
damper settings around 7 clicks
ride height personaly about 4 inch
Will try this myself when i return from Hols.
Cheers Nige.

HI yes if the trailing arms on a live axle setup are to far of parralel that will also cause some rear steering problems. Witch means that cars such
as the mk and luego need to run at about 5-6" ride hight at the rear .

It's an Indy (independent) so it's the rear wishbones in permanent droop by the sound of it.
Do you mean not parallel to the ground for the live axle trailing arms?, they must be parallel to each other to work or they will lock.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Hi for your average road going locost the arms parralel to the ground and each other will do. But if you want to take advantage of the fact that you
have a live axle then no all i will say is do some research on mallock clubmans. If you can get the geo right then it's amazing what you can get
the car to do. Get it wrong and the car has no grip and rear steers like a pig.

A mate of mine has an MK Indy with the same 'wandering' problem.
He asks what tyres are you running?
He has 195/60/14 Yokohama A048's.

Hi would be worth try the 4" rh to see if the change in geometry has any benificial effect on the front. the rear needs to be level or up to
1/4" higher at the rear but all this will only work if you have the right amount of travell on the shocks ie not hitting the bumpstops or
topping out . And don't forget that if you move the rh more than 4-5mm you will need to readjust the camber and tracking.
cheers matt
edit to say remember that all rh camber and tracking should be done with you or replacement weight onboard.

Are you sure that the lower rear wishbone slopes upwards from chassis end to wheel end when the car is at normal ride height?
If so then it sounds like an issue!
Rule of thumb is as follows:
Really the wishbones should move a roughly equal amount "above" and "below" horizontal in bump and droop.
They should also be somewhat divergent from the chassis end to the wheel end, and obviously the top wishbone will tend to need to be somewhat shorter
than the lower one in order to pull on negative camber in roll.
The fact that they are divergent obviously means that the amount of movement of the upper and lower wishbones is not strictly equal above and below
horizontal but you see the point I am making hopefully!
If all that is happening then the car should drive ok to a greater or lesser extent.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

There's no argument as far as I'm concerned - don't do a bodge to get through the SVA - fix the problem.

GTS have fixed the problem. (as have some other manufacturers)
The GTS bones/chassis set up has 7 1/2 deg caster and self centres perfectly without resorting to the MK bodge.
Experience is what you get when you don't get what you want!!!

Front Geometry
Has anyone got a drawing for the correct wishbones, so I can make some. I am new to the site, will you need my E mail address?
