does any body have favourable settings for the rear adjustable brackets

[KernowCooper]

Cooperman will comment here when he see it but whatever dont toe out, its liable to swap ends quite quickly

[tiger99]

There is no need to change the toe in from the original spec. Around 1/16" will do, more does not do anything except increase tyre wear and drag, while less, as stated above, may be dangerous if it tends towards becoming toe out. (Allow for some small amount of wear in the radius arms.)

 

Camber can be set according to personal choice, a little bit of negative, say 1 degree, is good, but only if you have a little bit of negative at the front, otherwise you will have massive power-on understeer, and still slight power-off understeer of there is too much negative at the rear. You need to keep the power-off condition as at least moderate oversteer to get round bends at the ultimate speed.

 

With the standard slightly positive camber at both ends, the initial understeer comes in quite gently, as does the lift-off oversteer. Give both ends a SMALL amount of negative camber and the understeer/oversteer will come in a bit more abruptly, which is fine if you really like to drive the car hard. (it is a Mini, so you will want to drive it hard!) But, contrary to popular belief, you will actually not get very much more in the way of ultimate roadholding. Too much camber, beyond about 2 degrees at either end, will actually give you less roadholding, although it may give the delusion of feeling better. The true test is by timing it on the same dry circuit with different settings, driving as hard as possible.

For road use the optimum rear settings are 1 mm to 2 mm toe-in and zero to 0.5 degrees negative camber.
These settings are the key to Mini performance and much more critical than the fronts.
For the front it's a matter of personal preference, but the generally accepted optimum settings are toe-out 1 mm to 2 mm with 0.5 to 1.5 degrees negative camber and 3.5 to 4 degrees castor (if you have adjustable tie-bars).
AS 'tiger' so rightly says, these are the settings for best road performance and it's what rally Minis are normally set to.

yes all my front suspesion is adjustable. thanks for the figures :)
