Cheers..
Expanding on this a little further, this is a similar to the MP9's TKi4 front-end upgrade over the TKi3; the B-block raised 2mm.
Although we could change the kick-up angle using the A-mount to 9 degrees, I wonder what effect reducing the kick-up angle from the B-mount would achieve
High and Low Roll center tuning options on the front-end perhaps?
Also what +1.4mm and +2.8mm represents in actual degree figures or the 'dots' system.
You could also maintain the kick-up angle by raising the the A-mount the same amount and change to a higher roll center only.
Possibly a useful tuning option on a super smooth high bite track or something like astroturf.
