NB Mazda Miata 1999 2000 2001 2002 2003 2004 2005 Monstrosity Junior Rear Diffuser

Two words describe this beast: Monstrous (Junior style) + Functional. That is why we've named this rear diffuser the "Monstrosity Junior.". Feel free to purchase this diffuser if you feel like standing out, making a statement, love the idea behind it, or simply want to improve how air flow exits the rear of your car.

Why this rear diffuser screams quality:

• CURVED 6-foot radius profile (rolled aluminum, NOT a forced curve) 
• Spans 46" between the rear inner tires
• Real life flow testing confirms diffuser's ability to maintain a very good boundary layer
• RAW ALUMINUM or POWDER COATED SEMI-GLOSS BLACK
• CNC (Computer Numerical Control) Precision Laser Cut
• High quality 14 gauge (0.065") 5052 aluminum construction
• Mounting hardware + brackets SUPPLIED
• Made in the U.S.A. 
• PLEASE allow a 20-28 business day build time - it's worth it
• We recommend further flattening the underside of your Miata for even better results (VIDEO RESULTS COMING SOON)
