When I did mine I put 1.5 negative bottom arms, uprated tie bars (std items
flex under heavy braking) uprated bushes at the front.
At the rear I fitted adjustable neg camber brackets, but was V unhappy with
them.  Mainly because although they were adjustable up and down (camber),
they were not adjustable front to back (toe in or out).  The effect was the
same as having the tracking out on the front.  My rear tyres wore out V
quickly on the inside edge.  I had adjusted the rear camber to 0 (no camber)
to keep the car balanced.  In future I would probaby just have the hole in
the std outer radius arm bracket made taller by 4-5mm.  I was more than
happy with the handling once it was sorted (165/60 12 falkens + spax adj all
round too).  Was going round the outside of a few minis at trackday at
mallory park, plus easily outdragging them out of hairpin due to high corner
speeds!!

I can strongly recommend the rear adjustable tracking / camber brackets - it
certainly sorts out the rear wheel alignment that will for certain be
wrong....

With the bolts a smear of copper grease or vaseline should do the job...

I put 1.5 fixed camber arms in the front. There are pros and cons to
negative camber. Here's what I encountered:
Pros:
-higher cornering speed, less understeer
-the steering wheel feels lighter, it is easier to turn it
Cons:
-the steering wheel feels lighter, makes it scarier at high speed and on
motorways
-any minor problem in the tracking of the front suspension is amplified. The
car is most likely to pull to one side if the suspension parts aren't in the
same conditions on both sides, which is common if you always drive the car
without passengers

I went back to standard camber after a few months, I prefer the handling and
it feels safer

The original subframe is made without holes for the radius arm and then the
outer bracket is fitted and the holes are jig drilled. This means that the
hole in the outer bracket is potentially in different places on every
subframe. How can a fixed neg camber bracket define where the original hole
was to 'add 1.5 degrees'??
Answer - It can't.

The same applies to the front lower arms to some extent. Except here they
will give an extra 'xyz' degrees of camber from whatever you had before.

In the case of the front there are problems either way.
If you fit fixed lower arms, you may end up with different camber on each
side.
If you fit adjustable ones and set up equal camber each side, you may end up
with different length lower arms.
Either way it will affect the symmetry of the handling.
