You would get better front end grip (laterally, turning) and worse accelerative/braking grip (minutely, splitting hairs). At the limit, a car with wider front tires would go to a more neutral balance, meaning less understeer and more oversteer. This is generally a good thing if you're looking...
PS, he bought it! It came with BavSound front speakers and an empty state of charge :)
But he's happy and that’s what matters. Now, we’re trying to figure out a home charging situation.
