Any road tests on e92 w/ sunroof?
Does anyone know if one of the mags or webistes out there have done a road test on a e92 with sunroof? I'm just curious as to how it the numbers would compare to an e92 with CF, an e92 with comp pkg, etc.
Thanks Last edited by ZenGuy; 08-31-2011 at 09:50 AM.. |

CF roof adds 75whp.

There isn't an appreciable performance difference, unless MAYBE you're a pro racing driver.
The most common reasons most people go for the moonroof seem to be: 1. They don't like the look of CF with their exterior color. 2. They want to be able to open their roof. 3. There's less road noise with a moonroof than CF. The most common reasons most people go for the CF roof seem to be: 1. It looks cool and isn't a common feature of cars in this segment. 2. They want the additional headroom. 3. It's known to cause speed.

The above posters have all stated the important stuff. I would say if you track the car go CF because if you're tall, your helmet may hit the roof but if this is a DD/Weekend ride then I wouldn't be concerned from a performance perspective.
Also, depending on exterior colour you may want CF (Melbourne Red, Alpine White, Silverstone, Space Grey). The lighter colours make the roof pop. In my opinion the darker colour don't matter as much (Jerez, Black, Interlagos etc). |

I have to agree having driven a e46 for many years with a sunroof and having not used it very often.
I purchase a new M3 with CF roof again in a heart beat it is a much better looker, lowers the centre of gravity and is lighter as well so there you have it

Well...
Tell me if I'm nuts but if we are discussing 45 pounds that is about 50 inches above the ground, wouldn't that lower the center of gravity as much as lowering our ~3600lb cars by about 0.65 inches? Is that not felt to be rather significant for handling?

On a serious note, curious as to how you calculated the 0.65".

I weigh 155. The majority of fat asses on this board probably push 200+. I'm safe with my moon roof.

I bought CF so I wouldn't have to diet.

calculation
Concept is Wt1X height1= wt2X ht 2 so 45lbs at 50 inches ht has ~ impact of wt of car at .65 ht difference Thought more and realized it's really the ht above the axle but that probably makes it = to 1/2 inch drop.
