Mazda RX7 FD3S Racing Front Brake Ducts / Backing Plates

One of the main problem with upgrading the standard front brakes to large discs is that the stock backing plates no longer fit.  The stock blacking plate also does not include a fresh air port. Another issues with the stock brakes and heavy track use on big brake kits is brake fade due to excessive heat build up.

The TGS Tuning racing brake ducts are designed to reduce brake fade when connected into the high pressure zone at the front of the car. The Ducts / Backing plates come with a 76mm / 3″ port where you can attach Flexible ducting hose (Sold Separately).
