Hello all I bought. A 5-door pearl white WRX on Sunday, the salesman did not explain the break in procedure on the vehicle. I've followed these cars since their release in 02. I was so over joyed driving a turbo again that when the vehicle had only 7 miles on it I redlined the vehicle several times to get a feel for it. I have been losing sleep ever since reading don't shift above 4k for the first 1,00 miles. Did I possibly damage my vehicle in any way? Please explain and elaborate as the more information the better and maybe I can sleep again. Thank you for your help everyone.
