1991-1993 BMW Convertible Top with Plastic Window -  Power Top Frame for 318i/320i/325i & M3 (E30)

Stayfast canvas is a three-ply composite. It is a tightly woven cloth canvas. The yarn is solution dyed before it is woven so the color is uniform throughout. Most convertibles that came with a cloth top were originally Stayfast canvas. Stayfast is more expensive than the vinyl options. This convertible top is a superior product with excellent wrinkle and U.V. resistance. Weatherability is superior and excellent durability and low temperature flexibility.

Twillfast canvas has the "dobby" weave on the underside of the fabric giving it a brocade type look on the underside of the fabric. Twillfast is an upgraded fabric and will wear a little longer than Stayfast. Twillfast is becoming the preferred material by many European convertible top manufacturers and would compare favorably with the German canvas.

German canvas is the original canvas used in many European cars like Mercedes, Porsche and BMW convertibles. This is the longest lasting top between the three canvases. This is due to an abrasion resistance on the exterior canvas. This convertible top fabric is also the most expensive.
