We have sold a couple to our current customers locally. Based on their feedback we are fine tuning. I believe one of the key differences that we will be able to offer over others is custom built to specifications. All roofs will be complete carbon fiber with epoxy resin but we have used core in some roofs that wanted extra stiffness. Thst costs a little extra in weight and money. I know other roof manufacturers have claimed 7 to 8 lbs. We think our racing roof will be significantly less than this.

Also, since we wont be selling this through any distributors, the target price is 1250 and the majority of that goes towards paying for epoxy resin and carbon fiber that goes into the part.

We will also be able to use finishing layers of some unique carbon fiber like wasp texture, labyrinth, or things like carbon kevlar hybrids in different color combinations.

Im looking forward to getting the first couple of these done and getting some photos posted soon.

Out of respect for Andrew teasing the community I'm holding off on posting the photos of my roof, but no one will be disappointed.

1x1 or 2x2?

The more CF roofs the merrier. Competition can only make these products better.

2X2


If fish oils and squatting won't fix it, you might as well be dead.

I have a steel roof with no sunroof like your old car. The paint on it has sun damage so I'm looking to get this fixed in the near future, hence, I'm willing to invest in other options as well.

I like the idea of a discreet CF roof, and would be interested in a painted-but-significantly lighter roof for a street car. However, I'm not convinced that a solution that would be stiff enough for street would really be that much lighter. What would it be prolly, $3k to replace for maybe 10lbs weight difference? Still, it is tempting. EDIT: $3k out the door, installed, etc.

2) people restoring them, who want everything 100% OEM.

3) people who bought them because they were dirt cheap, and now are having trouble with basic running costs/maintenance

... none of which are ideal CF roof candidates.
Not to mention that unlike the e46, the e36s have no real roof panel seam line. This would require a great deal of custom body work to fit and blend into the existing metal body structure. As mentioned a CF sun roof panel can be done relatively easily but the whole roof is a completely different animal.
