IMHO - springs are perfectly fine for most street drivers out there unless you have a specific ride height in mind. You can see some examples of M3s with AST springs in this thread: https://g80.bimmerpost.com/forums/sh....php?t=1847754.

On the HAS side, you can keep the drop conservative or go even lower - that's the beauty of a HAS kit.

Thanks!
