when i take off in first gear and let off the clutch and give it some gas to like 1500 rpm the whole car vibrates and shatters...but when i rev it to 3k rpm and let off the clutch it runs ok.....what could be causing this....i have a brand new tranny because it went out and a new clutch 2... i have the act clutch, the street disk....can it be the pressure plate causing this???? can it be the axle boot?any help will be appreciated...
i took my car to the dealer today and dropped it off.... but i want to know what u guys and girls think it is...

 

it's called chatter. welcome to an aftermaket clutch.

 

lol...no this aint normal....because i had the car running good for about 1 month and a half.....than i took it to the track than it started happening....
