By the way...for those track guys planning on keeping their M seats installed....I have a set of extra (member donated) seat backs that I'll eventually mold for CF. I couldn't believe how heavy just those parts were ! That again is probably another 20-30 lbs to lose ! |

Hi,
I just upgraded from a Z4 3.0SI to Z4M roadster. I don't like the look of the coupe and I don't like the OEM Darth Vader hard top... so I'm talking with a Fabricator on the East Coast to make a custom carbon fiber (structural) hard top. 1. There's two routes to with this...completely remove the soft top and use the coupe door glass and the carbon fiber hard top will have integrated quarter glass. The coupe door glass is pointed and not rounded like the roadsters. The 09 Z4 have pointed door glass as well. 2. The second option is to keep the soft top and make the carbon fiber hard top with the standard door glass shape and have a rounded quarter glass still trying for the 09 z4 hard top look. The question is...anyone willing to do group buy? I'm trying to lower the R&D cost of making the molds (the fabricator will keep the mold...he will be selling to us the hard top). I'm working with some photoshop folks to generate a photo... to post. I also like to get commissioned a new front bumper...Z4 just look weird up front. Beautiful sides and back. The estimated cost will be the same as OEM retail hard top. Any members interested? If you know any Carbon Fiber or Fiberglas fabricators willing to do the work on the west coast...please let me know... |

...since this is a thread dedicated to the coupe CF roof, I would suggest starting another thread to check interest in your roadsters project. (it will get buried here)

From reading your post, one might gather you don't really care for the baseline looks of the Z4 . Most folks LOVE the M front cover and Coupe roofline, but if they opted for the roadster....want to KEEP the function of the convertible at least until their snow season sets in. Removing the convert. top sounds like a personal one-off choice to me. You may be fully alone on that thought. Bare in mind, developing all the proper good looking hardware/fasteners and rear glass/defroster function as well as a precision fit and finish will be an expensive venture to fund out-of-pocket. I'm a little confused why your asking about a westcoast CF fabricator since all your references to development are in the east ? I personally have zero interest in handling it. I have Way too much work pre-scheduled for one thing. Best way to go about your query is to open a new thread and see where it goes. Pick a pro in the east and I'll advise as you go along if needed. Best of luck with your endeavor within this path you've chosen. |

Just a few more steps dialing in the substructure plug -(the area which will hold the honeycomb core).... And I'll be making the B mold.
Once this half of the mold is completed, I'll let it post cure over a few weeks while I task on other projects. Then it'll be time to infuse CF parts!! |

20-30 lbs reduction for the pair? Might be worth starting a new thread. This would seem to be a relatively good bang for the buck when it comes to dietary efforts.

Does anyone actually have a carbon roof on a Z4 M Coupe? I would love to see a picture of it. How much weight does it actually save? Last but not least. How much does it cost?

It would be nice to have CF/kevlar bumper beam like the E46 M3 to remove some weight at both extremity of the car.
I think it would be something not too hard to fabricate and the esthetic doesn't need to be perfect. |

An alloy bumper substructure would lose about 60-70% weight. |
