Brand new to minis...

Looking for a less expensive track car to use instead of my Cayman GT4. We just got a '15 JCW coupe, but not as a track car. I will DD this one and youngest son will drive it on weekends. I do not want to learn heel-toe so either need a newer F56 (with rev-matching for manuals) or an older automatic. Are the automatics workable on the track? I have never driven an automatic on a track except for Porsche's PDK which is fabulous. Is there a software upgrade that will add rev-matching to older mini manuals?

Either I have not found the right national-level forums or they are not as useful as the Porsche forums. Any suggestions you have would be appreciated.
