ISR Performance Rear Suspension Package - Nissan Z34/ 370Z

The ISR Performance Street Series Rear Suspension Package for the Nissan 370Z Z34 is a complete rear alignment correction package consisting of all three adjustable rear arms (traction, toe, and camber) with the rod end spacer sets needed for 370Z fitment. The single-purchase solution for converting to a true-type coilover and dialing in rear alignment on a lowered 370Z.

What It Does

Lowering a 370Z pulls toe and camber out of factory spec, and the factory bucket-style rear toe arm interferes with true-type coilover installation. The Street Series rear suspension package replaces the three factory rear arms (traction, toe, and camber) with adjustable equivalents that let you correct alignment back to spec, dial in aggressive alignment for track use, and clear the toe bucket interference for true-type coilover compatibility.

Buying the package as a single SKU is the better value path vs purchasing the three individual arm sets separately, and gives you everything needed for a complete rear alignment correction in one order.

Street Series vs Pro Series

The Street Series is the affordable budget-racer tier. Designed with a wide range of adjustment for accurate alignment correction on the street and weekend track car. For higher-end builds with serviceable Japanese spherical rod bearings, dust boots, thicker material, and FD-validated construction, ISR also offers Pro Series rear arms.

What's Included

• 2x Rear Traction Arms (with 2x 370Z rod end spacer sets)
• 2x Rear Toe Arms (with 2x 370Z rod end spacer sets) - factory bucket-style replacement, required for true-type coilover conversion
• 2x Rear Camber Arms (with 350Z/G35 AND 370Z rod end spacer sets included)

True-Type Coilover Compatibility

The Street Series rear toe arms replace the factory bucket-style toe arm. The factory bucket interferes with true-type coilover installation, so the bucket has to go - these arms ARE the bucket delete. If you're upgrading to true-type coilovers on your 370Z, these toe arms are required (not optional).

Fitment

• 2009+ Nissan 370Z (Z34)
