Eric,
on full soft with the 140# rear springs they are just about like a normal 914 ride...
on full stiff, they are going to be great at the AX....
After an event I will see if I can get the balance right with just the shocks and air pressures...if not then I may look for a rear bar to get the back end to rotate. I always like a car that is a bit loose...Kind of freaks out some of my students, but that is the way I like it, especially in a low powered momentum car
This winter I plan on doing a little detailing on the trailing arms and associated stuff
