G05 BBM lowering links, full install + pics + measurements

Figured this might help a few people out. Full installation and adjustment took less than 2 hours. SUPER easy.

I figured it would be easier to install them now, and just adjust them when the new wheels arrive.... rather than doing the full install + adjustments then.

My measurements are moderate intentionally. I did a 1/2 inch front drop, and a 1-inch rear drop, which to me, was perfect. I can go lower if I need to when the new wheels arrive. The measurements I provided, are based upon those standards.

This install is SO easy.... my instructions are pretty quick, because they don't need to be in-depth. Total time was under 2 hours, and that included taking pictures, writing down measurements, etc.

Easiest suspension install I've done in 25 years..... and I've done a lot.

Tools required:
Hairdryer/heat gun
8mm box wrench
10mm box wrench
Large screwdriver/pry tool
Small pair of pliers.

That's it..... literally.

Couple things to consider;

1. Front links need to be EXTENDED LONGER than OEM to lower the car. (Longer links go on the front)
2. Rear links need to be SHORTENED from OEM to lower the car. (Shorter links go on the rear)
3. You do NOT need to remove any of the wheels to install links, but you do need 2 floor jacks to be able to get the rear end up high enough to lay under the car comfortably.
4. Front jacking height to access = tires just barely touching ground.
5. Rear jacking height to access = tires 4 inches above ground.
6. Location of front links, = just aft of suspension, directly above tire.
7. Location of rear links = just forward of axle, just above control arm
8. To remove links, it helps to use a hairdryer or heat gun to heat up the ball/socket.
9. ALWAYS be sure to disconnect the electrical connector before you remove the OEM links. Don't forget to re-install it before taking the car off the jacks. Electrical connector is simple, no tools required. Squeeze and pull.
10. MAKE SURE THE CAR IS OFF.... NOTHING IS RUNNING..... NOT IDRIVE..... NOT THE RADIO..... NOTHING.

Let's start with OEM sport mode setting. Fender to center of hub = 16.75 inches.

Jack the front of the car up on both sides.

Locate links. Unplug connection. Adjust new links accordingly, install new links. Super easy.
