its not "corn". the correct word is "cone". wad it basically
means is that it has more refined synchros for firmer and more
precise shifts. conventional manuals usually have a single set of
synchromeshs to align the gears through every gear change. i
personally think its an overkill to have 3ple cones from 1st to
2nd. its actually more difficult to downshift and upshift between
the 2 gears.
