My new shift knob from Z1Motorsports (black one) compared to my Forged Performance. Love them both equally in there ways. Because of the aggressive shifting the Z1 knob feels a lot better ergonomically in my palm. Plus the lighter weight surprised me. I always preferred a heavier knob but it works great. Feels a lot more graceful.
But I will never get rid of my Forged knob. Had it for about eight years and it's been in my last three cars (350Z, G37, 370Z). Will go in my next vehicle. It's looks so bad ***.
