The JCR Rear Diffuser Fins is designed to harmonize with the complete JCR aerokit which create extra downforce without compromising drag. This product is designed to be retrofitted to your OEM DBA rear diffuser.  
This product is produced by 100% vacuum infusion technology 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 part manufacturers when it comes to fit, finish and design.
