So I have a 1998 r50 se auto 4x4 and would like to purchase the 4x4 design strut spacers and coil spacers and I asked him if I could run 3 inches spacers all around front and back without issues from control arms/axles/steering linkage/brake lines front and back. He said I could run two inches without problems but he doesn't know about 3. Does anyone know?
