The factory offset in the Speed 6 is +55.
The factory wheels are 18x7.
From what I have read just about any 8" wide wheel will require a roll, even if it is high offset like +48. Even the RX-8 wheels are hit and miss. Some people say you need a roll and others don't.
Which is true...
I run a 18x8 RX8 wheel, 50MM offset...
Lets go through my RX8 wheel history...

Never had rubbing, even on the lowered car....
I'll have some AutoEXE "Low Down" springs on soon, we'll see if it rubs then...
