HOW TO INSTALL:

Drill method:

1) Drill out base rivets with roughly a 9/64" drill bit.

2) Take car apart.

3) Pry open / remove base tabs holding in original wheel axles.

---for plastic bases, you can easily pry them open with small flathead screwdriver, or just snap them off with blade/wire cutters.

---for metal bases, you may be able to snap them off with wire cutters (careful as this will send the tab flying across the room!) if you cannot remove the tab entirely, you will need to use dremel disc to grind off the rest of tab. 

---if you don't care about the stock wheels/axles, you can also just bend them out to easily cut the axle with wire cutters

4) Replace wheels/axles

---if the custom wheels don't fit because axle is too short/long, you will need to adjust custom axle sets, see below.

5) Reassemble car.

---If you didn't overdrill, the base might just snap back together, otherwise you will need to lay car on it's roof and add some super glue onto the posts where the rivets used to be, or use some epoxy putty.

Optional: Lower car's ride height by sanding down the interior that holds the axles.

No Drill method:

1) Cut stock axles with wire cutter.

---you may need to bend the axles down to have room to cut them

2) Use custom axles: 

---1. Bend axle pins about 10-15 Degrees with pliers

---2. Insert bent pin into axle tube (if it won't go in, you've bent it too much, unbend a bit and try again, if it slides out too easily, bend it more)

---3. Insert 1 wheel into axle tube

---4. Feed axle tube with wheel through car's base

---5. Insert another wheel into axle tube on the other side of car/axle

---6. Insert bent axle pin into axle tube to lock in the wheels

3) Adjust as needed.

---if axle tube is too long: uninstall axle and trim with dremel disc and try again

---if axle tube is too short (rare): pull out axle pins slightly

---if there is play in the wheels, add spacers to fill in the gaps from wheel to base (you can make your own or use my 3D printed spacers for an easier time)

Note: if you don't use drill to open car, you can't lower the car's ride height.
