I am trying to find out what springs the manual e92 335i uses. I am trying to go back to stock and I bought a pair that were off an Auto (D3/D7). Supposedly auto uses D3/D7 springs and manual should be D2/D6 can someone verify? Anyone know exactly what springs the manual version uses compared to auto? Or what will happen if I run D3/D7 instead of D2/D6?
