Hello Matthew.

The list that I made have been updated but I didn't have the latest information when I wrote to the Brickboard.

Your cars rear chassi:

Rear spring: 3546893 std. T5

Rear sway bar: 9191459 std. T5

Rear "help spring": 3516327 std. T5

Rear shock: 9173318 std. T5 without levelling

So my conclusion is that you have the standard S70 T5 chassi without sportsettings or levelling option.

Hope this helps!

Let me know how it works out for you...
