The OEM rear suspension relies on eccentric bolts to set camber and toe, but those bolts are notorious for rotating under hard cornering loads and shifting your alignment away from where you set it. The IS-EL-S14 deletes those eccentric bolts entirely and replaces them with ISR's stainless steel lockout plates and Grade 10.9 hardware that physically prevents any rotational movement, so your rear alignment stays locked at your set angle through every hard corner, drift run, and track session. This is a mandatory upgrade for any S14 running adjustable rear control arms on a track or on a competitive course.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eISR Performance IS-EL-S14 eccentric lockout kit designed for the 1995-1998 Nissan 240SX S14 and S15 rear suspension\u003c\/li\u003e\n\u003cli\u003ePermanently deletes factory eccentric bolts that cause rear alignment shift under cornering loads\u003c\/li\u003e\n\u003cli\u003eMachined stainless steel lockout plates prevent any rotational movement at the rear suspension pickup points\u003c\/li\u003e\n\u003cli\u003eGrade 10.9 hardware supplied for maximum clamping force and zero-slip performance\u003c\/li\u003e\n\u003cli\u003eRequires adjustable rear control arms to set camber and toe after eccentric bolt deletion\u003c\/li\u003e\n\u003cli\u003eDirect bolt-on to factory S14 rear subframe mounting locations\u003c\/li\u003e\n\u003cli\u003eCompatible with both S14 and S15 chassis rear suspension geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eYear Range\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eTrim\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e1995-1998\u003c\/td\u003e\n\u003ctd\u003eNissan\u003c\/td\u003e\n\u003ctd\u003e240SX\u003c\/td\u003e\n\u003ctd\u003eS14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1999-2002\u003c\/td\u003e\n\u003ctd\u003eNissan\u003c\/td\u003e\n\u003ctd\u003e240SX\u003c\/td\u003e\n\u003ctd\u003eS15\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eIS-EL-S14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eISR Performance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eEccentric Lockout Kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eMachined Stainless Steel Plates\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHardware Grade\u003c\/td\u003e\n\u003ctd\u003eGrade 10.9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Chassis\u003c\/td\u003e\n\u003ctd\u003eNissan S14 (1995-1998), Nissan S15 (1999-2002)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment Type\u003c\/td\u003e\n\u003ctd\u003eBolt-On, OEM rear subframe pickup points\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrerequisite\u003c\/td\u003e\n\u003ctd\u003eAdjustable rear control arms required for alignment after installation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eISR Performance IS-EL-S14 stainless steel eccentric lockout plates\u003c\/li\u003e\n\u003cli\u003eGrade 10.9 hardware set for installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\u003cstrong\u003eWhat exactly does the ISR Performance IS-EL-S14 eccentric lockout kit fix on my 1995-1998 Nissan 240SX S14?\u003c\/strong\u003e\n\u003cp\u003eThe IS-EL-S14 deletes the factory eccentric bolts in the rear suspension of the 1995-1998 Nissan 240SX S14. These factory eccentric bolts are designed to allow camber and toe adjustment, but they tend to rotate under hard cornering loads and cause your rear alignment to shift away from its set position. The IS-EL-S14 replaces them with solid stainless steel lockout plates and Grade 10.9 hardware that physically cannot rotate, permanently locking your rear alignment in place.\u003c\/p\u003e\n\n\u003cstrong\u003eDo I need adjustable rear control arms on my S14 to install the ISR Performance IS-EL-S14?\u003c\/strong\u003e\n\u003cp\u003eYes. The factory eccentric bolts provide the only method of adjusting rear camber and toe on the stock S14 rear suspension. Once the IS-EL-S14 deletes those eccentric bolts, you must have adjustable rear camber arms and toe arms installed to set and maintain your desired rear alignment. Without adjustable arms, you will lose the ability to correct rear camber and toe after installation.\u003c\/p\u003e\n\n\u003cstrong\u003eWill the ISR Performance IS-EL-S14 fit an S15 as well as the 1995-1998 S14?\u003c\/strong\u003e\n\u003cp\u003eYes. ISR Performance confirms that the IS-EL-S14 is compatible with both the Nissan 240SX S14 (1995-1998) and S15 chassis rear suspension. Both platforms share the same rear subframe eccentric bolt locations and geometry, making the IS-EL-S14 a direct-fit solution for both generations.\u003c\/p\u003e\n\n\u003cstrong\u003eIs the ISR IS-EL-S14 for street use or only for track and competition use?\u003c\/strong\u003e\n\u003cp\u003eISR Performance notes that the IS-EL-S14 eccentric lockout kit is intended for competition vehicles. Deleting the factory eccentric bolts removes the OEM rear alignment adjustment mechanism, and this modification may not be street-legal in all jurisdictions, including California. Verify compliance with your local laws and regulations before installing on a street-driven vehicle.\u003c\/p\u003e\n\n\u003cstrong\u003eHow is the ISR Performance IS-EL-S14 different from running jam nuts on the factory eccentric bolts?\u003c\/strong\u003e\n\u003cp\u003eJam nuts added to factory eccentric bolts provide some resistance to rotation but are unreliable under sustained cornering loads because the factory eccentric bolt hardware is not designed for this use. The IS-EL-S14 machined stainless steel lockout plates and Grade 10.9 hardware create a physically rigid connection at the mounting point that eliminates any possibility of bolt rotation regardless of cornering load, providing a permanent and reliable solution where jam nuts only slow the slipping process.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes installing the ISR IS-EL-S14 change my current rear alignment settings on the S14?\u003c\/strong\u003e\n\u003cp\u003eIf installed carefully with the lockout plates positioned to match your current eccentric bolt positions, minimal alignment change will occur. However, since the lockout plate positions must be set during installation, a professional four-wheel alignment is strongly recommended immediately after installing the IS-EL-S14 to verify and set rear camber and toe to your target specification using your adjustable rear control arms.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat rear control arms pair best with the ISR Performance IS-EL-S14 on the 1995-1998 Nissan 240SX S14?\u003c\/strong\u003e\n\u003cp\u003eISR Performance offers a full range of adjustable rear suspension arms for the S-chassis platform, including rear camber arms, toe control rods, and traction rods. Pairing the IS-EL-S14 with ISR adjustable rear camber arms and toe arms gives you complete control over rear geometry with the confidence that your settings will not shift under load once locked in with the IS-EL-S14 plates.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat material are the ISR IS-EL-S14 lockout plates made from and will they rust?\u003c\/strong\u003e\n\u003cp\u003eThe IS-EL-S14 lockout plates are machined from stainless steel, which provides excellent corrosion resistance in the underbody environment of the S14. Stainless steel will not rust under normal use conditions and requires no additional protective coating for longevity on a track or street-prepped S14.\u003c\/p\u003e\n\n\u003cstrong\u003eIs the ISR Performance IS-EL-S14 a direct replacement for the S14 eccentric bolts without any modification to the subframe?\u003c\/strong\u003e\n\u003cp\u003eYes. The IS-EL-S14 is designed to bolt directly into the factory rear subframe mounting locations on the 1995-1998 Nissan 240SX S14 without any subframe modification, drilling, or welding. The included Grade 10.9 hardware replaces the factory eccentric bolt hardware at the same mounting points.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eSafely raise and support the S14 on jack stands at all four corners for full undercarriage access.\u003c\/li\u003e\n\u003cli\u003eNote the current position of the factory eccentric bolts on both sides to serve as a reference for alignment during installation.\u003c\/li\u003e\n\u003cli\u003eSupport the rear knuckle with a floor jack to prevent suspension droop while the factory bolt is removed.\u003c\/li\u003e\n\u003cli\u003eRemove the factory eccentric bolt on one side.
