• Jack + jack stands
  Low Profile Jack – Amazon – Please remember whenever working near or under a 240sx or any vehicle, please use jack stands properly. Jack up from a jack point, slide the stand under a secure point, and slowly lower the jack till the 240sx rests on the stand. You can keep the jack under along with the jack stand for added safety, another helpful tip is to take your wheel and slide it under a structurally sound spot just for a last resort.

Step-by-Step Instructions

Front 5-Lug Conversion (S13/S14)

1. Jack up the front end and secure it with jack stands.
2. Remove the front wheels.
3. Remove the brake caliper and rotor. Hang the caliper to avoid strain.
4. Remove the hub nut with an impact or breaker bar.
5. Pull off the stock 4-lug hub. You may need a puller or hammer.
6. Install your 5-lug hub and torque the hub nut to factory spec.
7. Reinstall the rotor and caliper.
8. Double check everything is torqued and spin the wheel to test.

Affiliate Note: Recommend a caliper hanger or bungee cords here. Never let the caliper hang down on it’s own, the shear weight along can potentially damage your brake line and you will not notice it till you push on your brakes and it begins to leak causing a safety risk. Please use a bungee or buy these super cheap hangers.

Rear 5-Lug Conversion (S13/S14)

1. Jack up the rear and secure with jack stands.
2. Remove the rear wheels, calipers, and rotors.
3. Unbolt the axle nut (use a breaker bar or impact).
4. Remove the 4-lug hub and bearing. This might be pressed in — use a slide hammer.
5. Press in or bolt on your 5-lug hub + bearing.
6. Torque the axle nut, reinstall rotor and caliper.

Tip: On S13, you may need to swap in S14 rear knuckles or aftermarket ones for bolt-on compatibility.

Final Checklist

Once you’re done, you’ll be able to mount any 5×114.3 wheels — including OEM Z32, 350Z, or wide aftermarket options.
