The tubular Xtreme Grip lower arms are installed next. CorteX sets the length before shipping, so no adjustment should be necessary to bolt them in with the stock bolts at the front and new Grade 8 hardware at the axle. Since our kit is the Street version, it uses a polyurethane front bushing to minimize the NVH into the interior. Note we used the upper bolt hole at the rear—that’s the preferred setting for street/autocross/road course traction, while the lower would work better for drag racing. It’s a quick switch at the track!
