Iv been wondering the same thing. I used to own an 04.5 VW Jetta GLI. The GLIs had a lower suspension than the base models. When it came to ordering lowering springs they would say 2" drop but would only drop my GLI one inch because it was already an inch lower than the base models. I now have a TL-S and want to know if this same type thing applies or if im good ordering Tein S springs for a little drop
