guess no body saw that i had an encounter like this. But it was with a lowly 5 series all stock. i was far from stock sans the motorsetup which was stockish 150rwhp.

falken azzennis 245/45/17's
300zx brakes on all 4
slotted rotors
ebc "red" pads
lsd
HKS hyper dampers
JIC magic rear toe and camber arms

and i could only hang with him in braking and corners. i'm an intermediate road course driver.
