Nissan 240SX - Performance

Aftermarket Parts

Suspension

The ideal suspension setup for the 240SX would be a set of coilovers with aftermarket anti-roll bars. Installing separate shocks and springs is beneficial, but chances are that the springs you are using are not specifically matched to the shocks. Manufacturers of coilover suspension systems match springs and shocks to achieve the optimal suspension setup.

Purchasing stiffer springs or lowering springs without aftermarket shocks is not a good plan. The stiffer springs will quickly wear out the stock dampers. If you absolutely cannot afford a full coilover suspension or springs/shocks/sway bars combination, the best thing to do is to buy either a shocks/sway bars or shocks/springs combo. Stiff shocks and sway bars will allow the car to turn with less body roll without having to purchase new springs. The more popular option is keeping the stock sway bars on the car and buying a set of springs and shocks. The combination of stiff springs and shocks with the stock sway bars will provide decent cornering capability.

For detailed information on what each suspension component does and how to adjust it, read the Suspension Tuning section or the Suspension Tuning summary (PDF Format, Excel Format).

In addition to the basic suspension parts described above, installing aftermarket lower control arms, tie rods, and bushings can improve your car’s handling. SPL makes a full line of adjustable suspension link upgrades for the S13 and S14 240SX.

There are two ways to allow for adjustment of front camber in the 240SX: eccentric strut-to-spindle bolts and upper camber plates. The camber plates generally offer an easier and greater range of adjustment. However, the eccentric bolt option is much cheaper than camber plates.

You can keep your HICAS system if you use non-metal bushings. The rear steering will bind if metal joints are used. If you plan to race your 240SX, HICAS is not such a bad thing to have. It will help improve the turn-in response of the car. The only reported drawback is that the back of the car does not feel stable in long corners. Try racing the car with HICAS before you decide whether or not to remove the system. If you are using the car for drifting, you will probably want to remove the HICAS since the rear wheels will react differently to various maneuvers (depending on your speed and counter steering). Sometimes the HICAS may help your drifting, and other times it may counter your drifting.

If you are not going to install metal bearings and joints like those that come on the SPL suspension components, then replace the stock bushings with a set of harder polyurethane bushings from NISMO, PDM Racing, or other manufacturer. This will improve the responsiveness of the car over stock and help eliminate wheel hop issues with high-power cars.

You may also want to install a 5-lug conversion while you are working with the suspension. The 5-lug as opposed to stock 4-lug setup will give you much greater freedom in choosing wheels and brakes. The S14 SE model came with a 5-lug setup. However, these parts are hard to find and may require replacing other components to get them to fit. The best option is probably purchasing a conversion kit like the Peak Performance PRO 5-Lug Front/Rear Hub Conversion ($1000 for the full kit).
