Z4 coupe carbon roof skin at Geoff Steel

Don't forget that it's not a finished fit item...you will need to do some stripping down, drilling and refitting to get it to fit nicely...unless you simply want the inside to look like a race car :P

Yes, I remember sixspeed's pioneering efforts back in 2007.

Yep it's gonna be an effort. Plus it will need a clear coat to stop yellowing over time. I got a few very small dents in my roof, so this is gonna be perfect for me. :thumbsup:

Haha your excuses to do more to your car are as bad as mine;)

The Geoff Steel page for this item states that shouldn't be a problem:

This item is manufactured using high quality, UV resistant resins and so there is no issue of the roof becoming “milky” after prolonged time in the sun
 
Even though there's a huge part of me screaming out what a fiddle it's likely to be, that it takes away originality and pretty much serves no purpose, I still really like the idea of one. 8)

But then it might look a bit daft on a standard car, I'd have to at least change the wheels.....Maybe a little drop to make the most of them.....Oh s**t, I've been here before :(

And the group buy is now closed. :D

Saved me from myself. Nearly bought one for a "future targa conversion", which would have been idiotic. :rofl:

Not had one but has been on my wish list for a year . I am in two minds as the weight saving is minimal and as has been pointed out in posts previously you may be better of just having your roof wrapped . If you are after weight saving you would be better of getting the tailgate that they sell but more expensive .
 
I've sat in a Geoff Steel roofed car - the quality was excellent and i've not heard of any issues of longevity.

Before he'd had a roofliner fitted, the CF is so thin, the roof did glow in bright sunlight - i say this as a positive; it looked cool and shows just how strong the material is.
 
Quality varied. That was the biggest issue, some were awesome, some were not. Shipping also left a lot to be desired, some turned up broken, some were packed really nicely, some were just chucked in a box.

From the outside, sun shines through the weave, if you don't have a roof liner installed, your best painting the underside black.

Not sure were you got your data, but there is a substantial weight saving in the carbon roof Vs the steel OEM roof.
 
Weight saving is 3.6kg (from the highest point of the car).

Mine was perfect, well packed, fitted without issues. It makes a hell of a noise when it rains though.

Hi Liam,

Regarding the noise when it rains. Did you keep the internal roof lining, or is it just the bare carbon above your head? I'd like to consider something like this, and would be retaining the roof lining, but don't fancy increasing the cabin noise!

Did you fit it yourself? And if so, was it much effort?
 
Mine is a race car.

I had my window fitter do it when he replaced the front screen. It is recommended to replace the windscreen trim at the same time because it joints the roof and windscreen. Theres a photo on page 16 of my build thread https://z4-forum.com/forum/viewtopic.php?f=2&t=112593&start=225

You'll need window removal tools to cut the adhesive around the roof skin. Totally DIY-able but for a pride-and-joy road car I would find a friendly windscreen fitter, as they'll also have the right adhesive/equipment for bonding the carbon panel back in place.
 
Easy enough to fit, just get some piano wire, (after removing the four bolts) and cut it off. :thumbsup:
