ISR Performance Eccentric Lockout Kit for Nissan 370Z, Infiniti G37

The ISR Performance Eccentric Lockout Kit deletes the factory eccentric alignment bolts on the 2009-2020 Nissan 370Z (Z34), 2008-2013 Infiniti G37 rear suspension, replacing them with machined stainless steel lockout plates and Grade 10.9 hardware. Eliminates the alignment-drift problem that plagues hard-cornered factory eccentrics, locking your rear alignment exactly where you set it.

What It Does

Factory eccentric bolts (the cammed adjustment bolts in the rear suspension that set camber and toe) tend to slip under sustained high cornering loads. The result: your rear alignment quietly walks out of spec over a track day or a few hard runs, tire wear gets uneven, and the car starts feeling vague in transitions. The ISR lockout kit replaces those eccentrics with solid stainless steel lockout plates secured by Grade 10.9 hardware. zero slip, ever.

Critical Setup Requirement

Adjustable control arms required. Once you delete the factory eccentrics, you lose the only factory means of adjusting rear camber and toe. You MUST have adjustable rear camber arms and adjustable rear toe arms installed to set alignment after fitting this kit. Without adjustable arms, your alignment is whatever it comes out at when you bolt the lockouts in. and there's no way to change it.

If you don't already have ISR (or equivalent) adjustable rear camber and toe arms, get them on the list before this lockout kit.
