818 Scrub radius?

[Frank818]

Does anyone know the scrub radius of the OEM 818, with FFR recommended front wheel offset and tire size?

Or at least, is it negative, dead 0 or positive?

Frank iirc, the scrub radius would be the difference between the ball joint axes and the tire patch centerline. There are variables for every setup but you can calculate your own. Camber, caster, wheel width, offset, etc.
