Nice channel, subbed. Awesome DRB you have there.Steve - yes you can use a replica GT40 for CAMS OR AASA competition. YouTube and search 200MPHGT40. You'll then see a wide variety of events that I have done. What you do with a GT40, real or replica is basically limited only by your imagination, chequebook and of course driving ability.
So buy one already and get on with it!
Cheers for the info.
