ISR Performance Pro Series Coilovers - Nissan 240sx 95-98

The ISR Performance Pro Series Coilovers for the 1995-1998 S14 240SX are the higher-end tier above our Basic Coilovers. 32-way adjustable damping, mono-tube design, 8K front / 6K rear spring rates, front pillow-ball upper camber mounts, and the kind of Japanese-bearing build quality that makes the difference between a track-capable coilover and one that just looks the part.

What It Does

Coilovers replace your factory shock-and-spring setup with adjustable damping, adjustable ride height, and stiffer spring rates dialed in for performance use. The Pro Series mono-tube design handles higher damping forces than twin-tube designs without overheating under sustained track use, and the 32-way damping adjustment lets you tune the same coilover for daily driving and track days. Front pillow-ball upper camber mounts let you dial in front camber directly at the top of the strut, replacing the rubber upper mount with a deflection-free bearing.

Pro Series vs Basic Coilovers

Our Basic Coilovers are validated on Enjuku Racing Formula Drift cars. The Pro Series is a meaningful upgrade above that baseline: better damping control under sustained load, the mono-tube body, the front pillow-ball mounts. Same shop validation lineage, more capability for harder use.

Fitment

Designed for the Nissan 240SX 1995-1998 (S14 chassis). For the S13 variant, see IS-PRO-S13 (89-94, same Pro Series construction).
