OK this has only happened twice, but both times it was going around a corner, pretty fast, downshifting to second, and the noise happens right around the midway point of the turn right after i fully let out my clutch. It sounds like a spring disengaging, like it had tention on it, and all of a sudden it disengages, that kind of a violent SPROING noise.... I can hear it with my music up, so it must be loud, and both times the passangers in my car said "WHAT THE HELL WAS THAT?" so im hoping it just some stupid thing like a peice of my suspention hitting somthing, but it sounds like its comin from right under my feet up in the front, i dont know what it is, and if anyone has any ideas let me know.

Thanks,

Matt
