Wondering which sprigs will Lower the car the most while still being able to run a 28" tall rear at the track without rubbing, I'm currently running the Prokit and would like to go lower as with a 28.7" tire out back I still have a 2.5 finger wide fender gap. I know Sportlines will rub. Which ones fall between pro's and Sportlines? I'm trying to avoid getting KW's just to get the ride height I want
