You do need to break them in. If memory serves correctly.......this is what I did:

Didn't get on it when I picked it up.

Kept it at/under 55mph.

Being that I live 70 miles away from where they were installed. I pulled over after 30 minutes to let them cool off for 15-20 minutes.

I repeated this regimen for 200 miles (only took another day to accumulate 200 miles as I work 75 miles away!).

I got this break-in schedule from a link someone posted on the Corral.net.

That is what Richmand says to do for a street car. If it is a drag car you can put them in and go.
