I have Aragostas, but I figured maybe powertrix or KTS would be similar. My bottom cup on the front coilovers rubs the arm itself. I wanted to adjust the height to raise up the car and realized that the adjusters are sort of wedged against the arm.
The only thing I can think that would help is putting some sort of spacer on the inside where the bottom of the coilover attaches.
