Good and bad.
Reductions in unsprung weight and rotational inertia were good but not super good. Regretfully, they reset my ride height when I specifically instructed them not to (because I had lowering links) so my ride height it back to stock. The gains from lowering are gone so I do not have a back to back reference from which to form an opinion.
The left rear damper cabling failed on the first hard right corner. The car is back in service to have this addressed. I reset my lowering links to stock length before I took it in for the cabling issue and asked that they, once again, re-calibrate the ride height so I can once again lower the car. Once I am back to my lowered baseline, I'll have a better feel for the changes but I've lost the direct back to back single item brake change modification.
