Moving to a smaller front tire will help with reaction time (less roll out) but how much depends on how hard the car leaves.
Every car reacts differently.
Hope that helps.

I think you mean .015 to .020.

Again it depends on the HP and the weight of the car on actually how much you will get.

My 2 Cents

Keep in mind 1 inch on the sidewall is not always 1 inch rollout.
Check your tire pressure often.
I personally don't think you will get more than a hundreth.

Went from a 17" to a 19" and did not see anything in r/t or et. It has to be there but could not show it.
