Default T56 issues

Anybody have some experience with T56 and 1st gear?
Car shakes violently (almost feels like the torque tube is coming through the floor) when starting in 1st gear. Not from a launch just normal take off 0-7mph maybe then goes away. Does not do it when starting in 2nd gear.

Do you know how old the clutch is ? How many miles on that T56 and when was the fluid last changed(drain, fill) ?

Clutch is RXT McLeod twin disk has around 4-6k t56 has 47k with fluid being the same (47k). I am doing a fluid change this weekend to play it safe. With the amount of vibration it leads me to being more serious. Car does make 670whp but has never been to the strip or done a launch in its life

Ceramic.inorganic clutch discs are going to chatter like hell on engagement and even worse when you need to slip the clutch (RXT), while for street or strip use (or in my case road course use since slip the clutch coming a gear high in some of the apexes to carry me to the straight before I need to shift again), want the organic discs (RST) that can be slipped with ease and and not chatter instead.

Ceramic that does not want to slip without a lot of chatter that you have in play,
