I have used a ABS/Disk Brake Saphire back axle. I am fitting 8J -4 rims. In the front I am fitting 7J +23 rims.
clearly I need costom front A arms.
Do I line the outside or inside of the front and back rims up for a track/race car?
clearly in a F1 car the outside of the front and back rim does not line up. I have calculated that my front bittom A arm will be 100mm longer than the BOOK design.

I would line up the outsides of the wheels to give maximum track.

I would have thought that the same applies for F1 cars as they must surely be designed to the maximum width allowed.
