Completely overhaul your 240z 260z 280z suspension geometry with the Track Attack Rear Suspension kit! This system allows you to get an economical and strong rear differential upgrade to your Datsun S30. Easily upgrade your differential to the Nissan 370z differential, which holds more powder and removes the weak factory stub axles and half-shafts and replaces them with modern 370z CVs.
Our Track Attack rear suspension package eliminates the rear mustache bar, and dog legs and converts it to a rear subframe that significantly strengthens the rear structure on the chassis. We also converted the McPherson strut to a modern double A arm dynamic. This lets you adjust roll center, anti-squat, camber, caster, toe, and many others. With this design, you can fit a wider tire than with the standard McPherson strut
Starting 11/01/25: kits ship with 300M rolled-spline axles, significantly stronger than the older 4340, and failure-tested over ~1,000 ft-lb / Tq.
Fitment notes:
Early S30 (1970–1973) require a minor spare-wheel-tub modification.
A small frame notch is needed to clear larger differentials.
Must use OEM CV axle ends!
4 Lug options available! Contact us for further details!
If Rod End / Heim Joint dust boots are desired, this kit uses 10: Rod End Dust Boots

The Apex Engineered S30 (240Z / 260Z / 280Z) TRACK ATTACK Rear Suspension Kit is designed for all 1970–1978 Datsun Z models. While it is a direct fit for the chassis, early S30 models (1970–1973) require a minor spare-wheel-tub modification and a small frame notch to clear the larger 370Z differential housing.
Installing the Apex Engineered S30 (240Z / 260Z / 280Z) TRACK ATTACK Rear Suspension Kit involves converting the factory McPherson strut setup to a modern double A-arm dynamic. This process eliminates the weak factory mustache bar and dog legs, replacing them with a rigid rear subframe that significantly strengthens the rear structure of your Datsun.
The Apex Engineered S30 (240Z / 260Z / 280Z) TRACK ATTACK Rear Suspension Kit replaces the outdated OEM McPherson struts with a double A-arm design, allowing for superior adjustment of roll center, anti-squat, camber, and toe. This upgrade also swaps the fragile factory stub axles and half-shafts for robust Nissan 370Z CVs and differentials, supporting much higher horsepower levels.
Each Apex Engineered S30 (240Z / 260Z / 280Z) TRACK ATTACK Rear Suspension Kit includes a lightweight, powder-coated rear subframe, control arms, and 300M rolled-spline axles tested to over 1,000 ft-lb of torque.
