I spoke to the guy at BAT and he told me that you can take out the rubber and it will lower the car about another 1/4", but with the squeaking issue, I didn't even risk it

I've got about 2 monthes on my set up, with the Bilsteins, and the front is 26" from the ground to the bottom of the wheelwell lip and the rear is about 25.75". I feel that it will lower a bit more, how much I don't know, but I'm happy with the set up overall
