Has anyone ever swapped out the OEM RS springs for some linear rate springs, like ERS (eibachs)? If so, what kind of rates? I've read the general consensus is that the car needs more rate both front and rear, perhaps something like 400#/800# for one that is primarily a track car on NT01's.

It would seem to me that doing this along with some GMG rollbars would be a great way to help dial in the car for the track without the expense of new shocks, atleast in the beginning.

Planning my future with this car, thanks for the input.
