Skidnation lockable eccentric alignment locks suitable for MX-5 NA / NB / NBFL. We ourselves use these locks in some race cars, with the result that the alignment still correspond to the initial alignment even after the highest stress on the race track. The two-part washers secure the eccentric screws absolutely excellent against rotation and thus adjustment of the alignment when cornering quickly.
Please note that the alignment with these eccentric washers takes longer than with original eccentric washers, but it is worth it!
The toothing of the discs corresponds to the markings on the original eccentric washers, each tooth represents an 18 ° rotation of the eccentric screw. The zinc coating makes them resistant to rust.
