An interesting difference I came across while researching pre-facelift 4.4 sport pkg Xs,
The pre-'03 4.4 spt pkg vehicles that where assembled with 18" wheels, came with "H" speed rated rubber, and an electronic speed limiter set to 128mph.
BMW began installing "V" speed rated rubber in '03, allowing removal of the speed limiter and a 143mph top speed.
Whenever I shop for a vehicle, I avoid speed limited ones!
