looking at a fast tarmac setup for my mini,
i have adjustable front arms and rear brackets and a lowered ride height.

what settings should i be dialling in front and rear?

camber
caster
toe

Front:
Camber: -1.5 to -2.0 degrees
Caster: -3.0 degrees <-- 3 degrees
Toe: 1/16" toe out

Rear:
Camber: around -0.5 degrees
Toe: depends how much oversteer you want

1/16" toe in is standard, start there and go toe out for sharper turn-in leading to greater oversteer.

i want better turn in, am i better off going toe out at the front?

If you want to increase your turn in - reduce the stiffness of your rear shocks :wink:

If you want to increase your turn in - stab your left foot on the brakes as your turn in. (this takes a lot of practice to get right)

When you do toe in /out on the front make sure you get ride height correct. The whole suspension on a mini was designed for a little granny to handle. not some bitumin rev head.
If you really want to get serious then look at the ackerman turn on the front wheels, bump steer, brake and accleration droop. These all can change your initial settings dramatically. Work out how much the suspension droops under brakes and try to set toe-in at this height. The front of the car will be more stable when braking.
I find that once the front is sorted then the back I run about 1-2deg negative camber and about 2 mm toe out . The back will try to pass you in a corner but with the right set up in front you find that you do not have to lift you foot to over come the under-steer.

Yep this is good except caster isn't negative. Also make sure you've got your ride heights on each corner setup correctly before you get it aligned. What tyres you are using makes a difference to your alignment settings too.

Standard rear toe-in is 1/8" NOT 1/16". 1/16" is enough for me. I'd not go negative on a road car... Minis are twitchy enough in a braking emergency.

I would start off with the standard toe settings and try different driving techniques before going down the path of changing toe for handling. Extra toe-out on the front can make the car weave on straights. Toe-in = stability. Toe-out = instability. Minis and most front wheel drive cars run a touch of toe-out on the front, it is only a touch though.

an alignment should hopefully sort out any issues i have, thanks for your advice it gives me some idea of where to go with it.

(this takes a lot of practice to get right) so you pull your right foot out , you put you left in, take you left foot out and shake it all about, do the hokey pokey and turn around all whilst blowing out off Commodores in your mixmaster induced wheezwagon - I think Master Stupor Mini should be OK with that

I have those bastard rose jointed lower arms that need to be removed to be adjusted..
