FDF Race Shop BMW E8X Mantis Kit Installation Guide
Description
Fully Assembled view of the BMW E8X mantis kit is shown for the right side
- Lower Control Arm
- Knuckle adaptor
- Bolt check regularly, take note of the orientation of all the components in this view*
- Do not exceed the rod ends adjustments, each rod end should have a minimum of 1 to 1.5x the diameter of the joint. (example, a ¾” rod end needs to have approx. 3/4”-1 1/8” inside of the arm at a minimum, this is 12-18 threads)
ACKERMANN PLATES
The kit includes +2, 0 and -2 acker Mann plates.
This is the difference in angle measured at full lock. Example- with 0 acker Mann plates installed the angle of the car will be 60 on the inside wheel, and 60 on the outside. *please note that alignment settings, rack position and other variables can effect the acker Mann curve resulting in differences from chassis to chassis, make adjustments according to your individual setup.
CUTTING AND GRINDING THE FACTORY KNUCKLE
The factory knuckle needs to be cut along the green line, just below the bearing bolt holes.
The knuckle will also need some radiused corners on the casting flattened with a grinder, to make sure the adaptor sits flat to the knuckle before fastening.
Alignment Recommendations
- Caster: 7 + or – .5
- Camber: -4 + or -1.0
- Toe: 0-1/8th out
- Wheel size recommendation: 18×9 +10 offset (close to this size will work well)
