I drive a three door, no mag ride, standard. Pitches like a ******* on a wobbly road, even at legal speeds ***. (I'd really like to fix that.) But so far, I've not experienced understeer. I'll reserve judgement as to where the limits present themselves once I get it on a track. You're right about the tail end though although I think that's something you'd eventually learn to drive around. Or file an insurance claim.
Don't lift off.
Especially not at speed on a bend on a track.
Jackie Stewart has a saying, and its particularly apt for the 3 door -
“Don’t put your foot on the gas pedal until you’re sure that you’ll never have to take it off again.”
