Here's my rear motor set up from the National.
In the end, I was fairly happy with it - upping the rear spring to a pink helped keep it stable on corner entry but with the conditions as they were, it was all I could do to get it clean for the next run.
Next time out, I'd probably run slightly thicker oils to help control things a bit.
Other than that, it drove sweet and was great fun sliding into the corners with a flick of opposite lock
EDIT - the sheet should say position 2 on the rear tower not 3
