I have a MY16 T32 4Motion 204 SWB DSG Kombi on 18" Sportline alloys with 255/45/18 tyres atm, what would be my lowering options for a modest drop? I wish to retain 4wd capability, but Im not planning on anything other than the odd off road camping site. I also dont wish to mess with the speedo etc or gearing, so plan on retaining the 18's. Thanks in advance.
