I have the Olthoff kit on my MKII SPF, initially found the shifting was OK , but certainty not Hurst 4 speed quality. Did not drive the car with the stock SPF shifter brackets so cannot compare the two. So in an attempt to improve the shifting, I eliminated the center console parking brake and related brackets, reorientated the cables around the engine and revised the one upper transaxle cable bracket for a straighter shot at shift box. I was going to do a gated shifter plate but the throws are so short and close, seemed unnecessary. Like the shifting now, very easy and on point. I posted some pictures of all this sometime back, but will post some additional when I get back to where the car is this week end .
