This product is produced by 100% vacuum infusion tecnology and post cured at 100 degrees celcius for maximum strength and precision.

 Note
Unlike most retailers of RevoZport products, we have worked directly with RevoZport in the R&D of many of their designs and of course, we have installed their products ourselves. 
RevoZport stands with the best in the world of aero parts manufacturers when it comes to fit, finish and design.
