This is exactly the setup I have had for 10 years with no issues ;)

One thing that should ring alarm bells is the fact that using the rubber inner UJ's that a Cooper is fitted with, with lower suspension is the death knell for them. They can NEVER retain a neutral stance. Parallel is always the optimum.
one of the major manufacturers did a clever joint with a std u/j fitted into nylon cups, the rollers running direct on the hard nylon, much longer lasting than the rubber doughnut. i think it was QH
Yes I have replaced the rubber u joints with the QH u joints as well much better design, and dont sit quite as close to the exhaust

I am very happy with it, took it for a long drive yesterday with no issues at all and still a very smooth ride, it is good that now it not only has no pitch but i can also corner it with a fair bit of enthusiasm :D
