Hi Have a question ? Did my Civic FK2 want to combine a lowering of 40 mm with a track width of 40 mm. Does this work or does the tire then put on the wheel box. Maybe someone already has that. Wanted also to install new boxes and a power stage. What do you mean. Rather do it yourself or have it done at ACR ??? Would like to keep original radio. mfg Dr.Civic2006
