I tracked my GT3 for the first time today. I took it pretty easy because it was my first time on the track with the car and I want to preserve my PCCBs until I change over to steel.

Anyway, heading home I noticed that when hitting a small bump at slow speeds there is a "knock" and a "rattle" that I feel coming from up front. I cannot replicate the noise by bouncing the car up and own or by shaking the wheel. Any ideas before I start any disassembly??

Could be your sway-bar...

 

Have you had your front wheels off yet??? Sometimes the dealers forget to remove the plastic spring spacer from shipping. It prevents the spring from fully compressing...If you hit a good bump, you get a good bang sound from this...Don't ask me how I know....If it's not that, probably the sway bar has loosened as Slothman suggested

 

Same as Metalsolid says, check the sway bars. There have been a few reports of the mounting bolts loosening a bit after some track time.

There, now I said it too...

Karl, should you get a chance... pop out the front pads and post a picture for comparison. Here are mine after taking it easy for two days at the track...
