My local BMW dealer also offered this option for my M Roadster. I don't recall the exact cost but as I recall it was around $1,000. I have on one occasion exceeded 155 MPH in 5th gear reaching about 160 or a little more. I was still accelerating but was running out of road so I had to slow down.

i've had mine flat out in 6th at 250km/h.... there was more revs to go but felt like that was the electronic limiter holding it there...

I've had mine on just under 280 km/h (175 mph) on the speedo but then I ran out of road.
That was 100% stock wheels/tyres/software & no aero/wings etc.
There wasn't a visible decline either.

I bottled it and slowed down :oops:
I second this was right behind him :driving:

Ye Tis, front started getting lighter above about 160. Would need to change the aero on the Roadster to go faster. :wink: Just don't put the roof up. :lol:

Seen 168mph (270km/h) in 6th on Autobahn, then stock as far as I'm aware of.
(dunno if previous owners reprogrammed anything)

Front end much more planted with front spoiler! :)

Is that indicated or gps verified? If indicated that could still fall within the 155mph limiter?

I suspect having the roof down is what did it. Must create a little more drag and lift. No figures to verify that, just empirical observation. :)

No limiter on the Alpina, and an official top end of 169mph (172mph with the hard top fitted). Would expect a delimited ///M to be something similar.

Not my picture, but one posted in a previous discussion about V max:

[IMG]http://i886.photobucket.com/albums/ac70 ... 51e84a.jpg[/IMG]

I've seen an indicated 175mph previously but ran out of road / bravery. I wouldn't expect much more even with the limiter removed.

I've had clocks sitting at/just above 180, GPS showing 178mph on the autobhan last year. I assume this means there is no limiter on mine but nothing in the paperwork about having any kind of performance pack :?

Only 2mph speedo error at that speed is highly impressive, has it been corrected through the software? :o
