The stock eccentric bolts provided by Infiniti for small rear toe adjustments tend to slip under high cornering loads, causing changes to the rear alignment. Our SPL Parts Eccentric Lockout (EL) kit eliminate the stock eccentric bolts to keep your rear alignment where you set it. You must have adjustable control arms in order to adjust rear toe after eliminating the stock eccentric bolts. Our lockout plates are CNC machined from 6061-T6 Aluminum and supplied with zinc plated grade 10.9 bolts and locknuts for absolutely zero-slip. One kit includes washers and bolts for both rear toe arms.Made in the USA. Applications: 2014+ Infiniti Q50 V37 2017+ Infiniti Q60 CV37
