@LI-Rick IMHO a Quaife isn't necessary in a Spyder. The car is so light.
I can't fit one with my 3.44 R&P. It will fit with a 3.88. But IMHO the gearing is too short with anything BUT a 3.44(and a 6500 rpm limit). The tallest 2nd gear available is a 1.93 now.
Unless your motor revs to like 8000, like Phil's. Your mileage may vary...
I leave two stripes with 180hp.
