Cutting a loop always increased the spring rate. The part about cutting is that it was never tested by the engineers that built the car, nor anyone else so there is no telling how it affects handling, so it can be totally unpredictable and can be dangerous.

Going with an aftermarket spring such as Eibach etc, or name brand coil overs is a more better approach as they are designed and tested by engineers for increased handling performance and usually backed by a warranty. The handling performance will be safely increased and predictable.
