A modified or tuned engine is always going to be more temperamental imo. Standard is great for just sitting in and driving. also best for learning to be honest. Although judging by that video you'll have no problems handling the car even with the extra power.

I've drifted a good few tracks. Be willing to travel. Watergrasshill (Cork) is awesome and Tynagh (Galway) is probably my favourite track in the country.
