ARP 3.0" Long Wheel Stud, M12-1.25 for Subaru / 86


These press-in splined wheel studs can be used on most Subarus that utilize OEM M12x1.25 press-in splined wheel studs, like the BRZ/FR-S/86 - both front and rear. These 3.0" long studs come with yellow zinc plating for corrosion protection. Designed to work with our M12-1.25 thread pitch lug nuts, which are sold separately. These will work with up to 15mm hub-centric spacers, or no spacer at all. This catalog entry is for A SINGLE WHEEL STUD ONLY.

Why are longer wheel studs preferred?

  • Longer studs ensure proper lug nut engagement, especially with aftermarket wheels and/or wheel spacers.
  • These 3.0" long wheel studs allow the use of a variety of hub-centric wheel spacers (up to 15mm thick) - or without spacers.
  • When these long studs are coupled with our Vorshlag M12-1.25 Long Reach Lug Nuts (also available in this section) your wheel is held on by more threads than the OEM stud + lug nut. Our nuts are BIG!
  • Closed lug nuts will not work - use an open ended lug nut!
  • Quality Italian made in the USA by ARP 
  • Splined head must be pressed into the hubs.
  • We recommend the use of a light application of anti-sieze thread lubricant for more consistent lug nut torque torque

FOLLOW THESE INSTALLATION INSTRUCTIONS: Remove the wheel hub assemblies first. Then press out old studs using a hydraulic press, making sure to support the hub face to prevent damage the hub bearing. Press in the new splined studs into hubs using the hydraulic press. Make sure that the knurl is fully engaged and the head has bottomed out against the back face of the hub.

The front hubs are relatively easy to unbolt, and they are shown above after the new studs were installed.

The rear hub assemblies also need to be removed to extract the old studs and install the new longer versions. First you take off the half shaft retaining nut, then you unbolt the hub assembly from the emergency brake bits and you can remove the rear hub. Once removed from the car, you can use a press to push out the rear studs; the new studs go in the same way.
