The bottom of my comfort coil perches have 4 threads from the bottom and my battery pack is about 4.5 inches above the ground. I can lower it another 1/4” with the 4 threads, but I think that is too low for the parkades and driveways I visit. This pic is after the suspension settled and I had to drop the front coils about 1/4” to match the rear as the battery in the front was 4.75” and the rear was 4.5” from the ground.
