The biggest improvement of the 1.8TS (and 2.0TS) over the 1.6TS is that
the front brake discs are 284mm (bigger) and ventilated (survive harder
abuse).
Also it's easier to find proper race grade pads for those calipers, pads
like PFC
or Ferodo DS3000. (And yes they work on cold mornings in Sweden too.)
Rear brakes are discs, but that's not very important.

To sum it us: Small improvement in engine performance and a large
improvement
in brake performance. Means you will lap a lot fater on track days.
Also the shocks were a bit better, but are probably worn out anyway,
so you will need to upgrade them anyhow.

Have fun,
Kristoffer
