I think this is perfectly acceptable! While they may be slow and small, I have always admired Miatas when they hit the track. It looks like you were having a blast and pictures are great.
This make me want to track day my Mustang some day. Just need to throw the sway bar back on the front and remove the drag springs.
I am going to have get two full careers going in order to have any chance at affording everything I love.
