Competition Coupe Brake Ducting for SRT-10 calipers. Will fit Gen 3, 4, 5 cars (not ACR-E calipers) The ducts are fiberglass with a carbon overlay. These are very light and sturdy. The caliper mounting bracket is also included in the price as you have to buy those separately from Dodge Viper Racing. I used these for 1 test day before switching to a different caliper set up. They show as new. Price also includes shipping in the lower 48.
