- Huge -30mm to +40mm adjustment range
- Feature high quality 5/8" Teflon lined pillow ball rod ends which eliminate the flex found in factory rubber bushing offering a more direct and predictable feel.
- 28mm, 3mm wall thickness 4130 chromoly tube with CNC machined ends, TIG welded and e-coated for a long lasting finish. 
- CAD designed, FEA tested and rigorously used in our own F80 M3 race car

NOTE: In some cases the edge of the brake line mount needs to be trimmed to give clearance to the arm, this does not effect the function/position of the mount.
