The PS with a heavy knob (get a z32, thank me later) is hands down the best setup I have ever had on a b13. Tho a modded b14 shifter looks like it would be good too. Maybe zap a spot weld on top the keep tue ball in place. But after my PS install every shifter felt like garbage including BM, it was far to notchy and required a good bit of effort to overcome the trans' detents. That to me makes the shifting slower.
