Option parts XRAY T4’20 3.0mm graphite bumper upper holder brace décembre 2, 2019 by Chris Leave a Comment XRAY have introduced a new 3.0mm graphite bumper upper holder brace for the new T4’20. The graphite bumper upper holder brace is mounted on the top composite or graphite upper holder for the bumper and it helps to reduce chassis breakage in serious crashes. The brace matches the shape of the bulkhead so if a crash occurs, the brace touches the bulkhead and protects the front of the chassis from breakage. Shopping! Wartelle Shop Shopping!
