Just drive it like you don't care about it, don't think about the consequences and you will be fine. An EJ20R TT in 3rd/4th gear is generally very close to as fast as an STI. I know when I was young and naughty I definitely surprised a few STI and EVO owners.
But really the best feature of the TT wagon is it's ability to go sideways. They are very loose cars if you drive them hard enough on road tyres.
Ohh and related topic, I have a BH5 as my tow car, and ended up using it as a safety car on Targa last year, 5 min gap and I still managed to catch some of the Targa Tour cars in some stages... Although to be fair that car does have 4 pots on it, as I had some fire issues with the stock brakes.
