Default This can't be normal

Ok. I have a Monster Stage 3 Clutch. And the Monster Slave Cylindar that came with it.
Yes it is an aggressive clutch (rated at 700rwhpp/rwtq)
however i dont think this can be nomal...

ok at any given time, any speed, and gear, i constantly feel a thumping/tapping on my foot thru the pedals (especially if im in too high of a gear)

AND....

when im at a dead stop, when i release the clutch in first i sometimes let it catch and let the force of the clutch start pulling my momentum forward without using the gas (i figured this would keep me from glazing the flywheel)
when i do this there is a RIDICULOUS cluncking/thuding not a grinding noise. it does it worse when i have the wheels cut
the only way it wont do this is if i rev it up to 1500/2000rpm
it has 2000 miles on clutch, the last 1300 ive beat this thing so much (4K dumps, brake stands, hard down shift, chirping tires thru 4)
and its worse now at mile ~2000 than mile 1

and i believe this is normal but i will share anyways...

in reverse, the whole car shakes ( not near as bad as it did at first so i think its normal for this aggressive of a clutch)

Could it be:
Hydralic problem?
Needs Realignement?
Needs Fluid Flush and Bled?
Help please
*****(clutch was professionally installed)*****

What are the conditions of your motor/tranny mounts?

Motor mounts are brand new. tranny mounts are more than likely stock.
would that really cause this?
my stock clutch never acted like this and it had 89XXX miles on it (yes it would slip ALOOOT)

the motor and tranny were both dropped because obviously i had the clutch changed and i had the motor replaced

I genuinely doubt that it is something to do with the clutch with how you are describing it. Have you had the car put on a lift to make sure the transmission mount is in good shape and nothing is obviously loose, etc.?

We've had customers that bring cars in with broken transmission mounts that make similar noises to what you're describing. And considering how you've been driving it I wouldn't be surprised if that is what's going on. If you have any other questions or want to go over things in more detail just give us a call.
