2 Essential GR Corolla Mods You Need Now

Are you ready to take your 2023 GR Corolla to the next level? If you're looking for affordable and high-impact gr corolla mods, you've come to the right place. In this blog post, we'll walk you through two essential modifications that every GR Corolla owner should consider: installing tail light overlays and upgrading to extended wheel studs and larger wheels.

Installing GR Corolla Tail Light Overlays

One of the quickest and most affordable ways to give your GR Corolla a unique look is by installing tail light overlays. Here's what you'll need:

  • Soapy water
  • Microfiber towel
  • Tail light overlay kit

Follow these steps for a seamless installation:

  1. Prep the surface by spraying soapy water on the tail lights and wiping them down with a microfiber towel.
  2. Carefully align the overlay with the tail light, starting at one end and slowly working your way to the other side.
  3. Use the microfiber towel to work out any air bubbles, being mindful of any stamped logos on the tail light.
  4. Repeat the process on the other side.

While a heat gun can help shrink the overlay around stamped logos, it's not required for this installation. Once you've completed both sides, your GR Corolla will have a sleek, custom look that sets it apart from the rest.

Upgrading to Extended Wheel Studs and Larger Wheels

To accommodate larger wheels and improve the overall fitment of your GR Corolla, upgrading to extended wheel studs is a must. Here's what you'll need for this modification:

  • 3/8 breaker bar
  • Hammer
  • Smaller ratchet
  • 12-point 30mm socket (for axle nut)
  • 21mm socket (for wheel removal)
  • Lexus IS300 wheel studs

The installation process differs slightly for the front and rear wheels:

Front Wheel Stud Installation

  1. Remove the caliper, rotor, and axle nut.
  2. Swing out the lower control arm to pull out the axle.
  3. Remove the 19mm bolts holding the wheel bearing to the knuckle.
  4. Press out the old studs and install the new Lexus IS300 wheel studs.
  5. Reinstall the wheel bearing, axle, rotor, and caliper.

Rear Wheel Stud Installation

  1. Remove the caliper and rotor.
  2. Remove the four 17mm bolts holding the wheel bearing assembly.
  3. Tap the axle loose and pull out the wheel bearing assembly.
  4. Press out the old studs and install the extended wheel studs.
  5. Reinstall the wheel bearing assembly, rotor, and caliper.

When installing your new wheels, be sure to use hubcentric adapters and aftermarket lug nuts for a perfect fit. The ideal wheel specs for the GR Corolla are 18x10 +35 offset, which allows you to run a meaty 285 tire for improved track performance.


By installing tail light overlays and upgrading to extended wheel studs and larger wheels, you'll be well on your way to creating a GR Corolla that stands out from the crowd. These affordable GR Corolla mods not only enhance the appearance of your car but also improve its performance capabilities.
