This X4 rear CV axle is rated to 800 HP and drops into the GR and VA chassis STI without touching the differential or the hub. Driveshaft Shop turns the shaft from 300M bar stock and fits a 300M splined stub into a chromoly CV housing, a build aimed at street cars that also see drag, road course and autocross duty. The part is symmetrical, so one unit covers either the left or the right side of the car and two are needed for a full pair. Driveshaft Shop covers it with a one year warranty.
