Where did I go wrong?
Both front tires rub on the frame but I think I followed the recommended wheel & tire sizes.
FFR Manual, page 472: front optimum tire size: 215/45/17
Here's what I have:
2006 WRX sedan aluminum lower control arms
FFR upper control arms - driver side cut per manual revision
eyeball alignment - not exact yet, but close
17 x 8 Enkei Racing RPF1 wheels
215/45ZR-17 Michelin Pilot Super Sport XL tires (20 psi), overall diameter 24.7"
Ride height: 4.5"
Both sides rub on the frame behind the wheel well at less than full turn.
