Ok, so. I've watched videos online, read articles, but I still can't really make sense of it.

From what I gather it affects toe-in / out depending on positive / negative SR when braking,

and a 0 scrub radius when cornering can cause uneven / excessive wear on one side of the tyre.

So, on an MX5, for super grip ultimate handling for very turn honour, what would one be looking for when purchasing a new wheel / tyre combination? Would a negative scrub radius help with turn-in, and even tyre wear?

Help me Nick from MOT, you're my only hope! (Not really, but y'kno Star Wars quote and erything)

Thanks guisesesese.

Scrub radius effects steering feel and self centering. MX5 is positive Scrub Radius as standard. The more you add ( bigger offset wheels) the more the car will tramline, you can reduce this by playing with the caster.
