The V's are heavy for a road course, BV Mully's info is spot on. Be careful on having your son win the HPDE event, overconfidence in a novice group will lead to a smashed car and further issues. If you really want to kick ass at an HPDE event buy a Miata, hire a coach and run rungs around everyone in your group with it. That's what I do and it never gets old.
Glad your on the track and having fun.
