I looked at the results from last year. Looks like the fastest bimmer was a M5 at 170.4 mph. I found the second fastest interesting because it is a 128i convertible (like mine at least superficially) at 160.5 mph. I'd like to know what mods he has! There were also a couple in the 150mph to 160mph range.

You'd need higher speed rated tires and the speed limiter changed accordingly to exceed the 150-160 mph range. Regardless of your capability the electronic nanny will stop you before your tires fail.
