Really appreciate your contributions to this discussion.

This only applies to 1M/M3. If a 6" front main spring is used, a helper spring is necessary. With a 7" main spring you can get away not having helpers if you don't lower the car too much.
You would only need a helper in the rear if you rear main springs become unloaded with the suspension at or near full droop. Is that the case right now? I personally ran both 7" and 8" rear main spring with a helper on my 1M.
Here is a photo of the RS1 front strut with 6" main and helper. You can see how a 6" or even a 7" spring can become unloaded without a helper in place.
