The track I run on has so much bite, it might as well be a carpet track. I did run the lowered towers. WYD is correct, I only have about 5 packs through the car so far.
I did not know any better when I put on the lower towers with rubber tire, but was to lazy to change them back. I would venture to say if you are going to run rubber tire (63mm) stick with the stock towers. In the front of the car with a white spring and the lowered towers I had to back the shock collar all the way back to get just under 4mm ride height. You should just stay with the stock shock tower so there is more room to adjust.
