How do these compare to spec.B top hats, performance-wise? The spec.B bearing would be larger, yes? How must difference does that make?
I used spec.B top hats when I installed my Konis, but I'm considering switching to these to eliminate the ride height increase from the extra washer. Would I be spending money on a downgrade?
