Autocross??  The one time I did that I beat the dog shit out of my tires..

though, I went into full lockup a few weeks ago up near LAX and was within
inches of bending the mofo..  :0

Yeah, I'd say the idle is *very slightly* rough.  I still have that 
knocking sound at speed under load, it's done it forever, not sure what
