I Broke my BDR help!

[moneymanager]

Hi Gang.

Friday after Thanksgiving I raced my Backdraft at Firebird and during race #2 I broke something and had to come home early.

I haven't figured out what I broke yet so maybe you can give me some IN-PUT to help me figure it out.

It's something in the drivetrain. It runs, shifts and moves under it's own power but around 2,000 rpm it makes a terrible noise and causes a shuddering effect which can be felt through the whole car, especially in the clutch pedal, every few feet it moves in distance.

It doesn't do it upon first accelerating, only after you get around 2,000 rpm or higher, in any gear. I'm told the brake lights are coming on as well each time it does it, like the brakes are locking up speratically. Although I feel it more in the clutch rather than the brake.

I have a feeling that maybe part of the clutch disc has come apart.

What do you think it might be?
