Before anyone questions the wisdom of doing this, I have tried (although not on the track at speed) and the seat is stable and there is plenty of clamp to insure it will securely and safely stay attached to the seat mast without rocking. I will post pictures when I am done with the conversion.
I've done a 1cm shim using my 2nd generation TK1 and the most recent TK FRD with no issues.

I think you'd feel it pretty quickly if it were not gonna work.
