Their rubber is about 30 % stiffer in both directions thus giving slightly better steering
precision and some minor advantages on cornering. Remember strut mounts are made
from rubber with a steel inlay.
These are stock Golf/GTI strut mounts (and bearings):
TT mounts look almost the same but have two teeth instead of one. The bearings
remain the same (but I'd always get new SKF ones when changing suspension).
I guess they also better withstand the increased forces of uprated suspensions
with deforming giving the bearings a more stable platform and longer life.
I had them fitted 7 months ago and the difference in feel has been clearly noticable.
