The Xray T4 '19 2mm Hard Shock Tower Set is made from 100% premium carbon fiber which utilizes a varying angle layup to provide an uncanny resistance to flexing/twisting. During our development, we have found that these towers help calm the car down in high bite conditions.
Not as stiff as most thick kit shock towers but they are very resilient in supporting your rear body mounts. The set allows you to remove 4 grams of weight from up high which is at least worth 1 second per lap (jk on the time improvement).
