The latest addition to the X Factory Infinity line of parts is front and rear shock towers for the Hot Bodies D413.
The front tower replaces the standard Hot Bodies part while the rear one replaces HB112802, the kit-standard (B) tower.
Both towers have a small but significant X Factory improvement:
There is more material on top of the shock mount holes and more material outside the last hole to reduce the possibility that the shock mount bolt will rip out landing a jump.
This also helps with abrasion when the car is up-side-down.
Most important, the X Factory Infinity CF towers are far less expensive when compared to the original kit versions.
