OK, I do feel fairly qualified to post an answer to this one
On the
very first TTs, lift off oversteer was a problem.
ALL of them were recalled - although as stated, in the UK some of the fixes (such as the spoiler) were optional.
Cars from (roughly) 2000 onwards also got traction control as standard (Audi version of Honda
VSA), which was part of the recall.
There are likely to be no more than (literally) a handful of cars out there which weren't modified - although they do exist.
The results of these changes were a car which was a lot 'safer' but ultimately a bit more boring to drive.
You can provoke lift off oversteer - but only if you're trying very hard to do so.
What is a
lot more likely is understeer, but can be a bit of a PITA to be honest - especially if you boot it round a bend and the
VSA kicks in, reducing the power, just as you get the understeer...
Having thrashed one or 2 TTs in various guises, including some putting out a rather healthy number of horses, around Castle Combe, I've got to say that it's quite difficult to upset a TT to the stage where things get scarey.
Do-able, but you've got to be doing something pretty stupid.
Ultimately though, the best traction control / driver aids / most massive brakes in the world aren't going to help you if you approach that corner 20mph too fast with your brain turned off...
