I never advise students for or against DSC, but I prefer them to run DSC off on their own if they have any kind of decent car control. DSC full-on builds bad habits, habits that take a lot of time to fix later on as the driver progresses. MDM is a little better, but still allows drivers to progress too quickly without ever having to learn skills I consider essential, such as throttle modulation and countersteering. The E9X chassis is REALLY easy to drive fast, and one of the best cars in that performance bracket to learn to really drive (DSC off). YMMV.
To counter my own point, I will say that if you are a completely green student with zero experience, I'd probably suggest MDM on. First track day is overwhelming, and would be ruined if you had a crash.
