I wouldn't track that rog,it's far too nice a car and if you bumped it you'd be gutted,not 100% but would the t4 be a bit laggy for track use?im no expert though.
Loads of fun track beasts out there you an tow easier as well,I'd say you'll have as much fun in a 2.0zetec ka etc and not really care if you wipe it out compared to the cossie where you'll be thinking "shit if I bin this or something pops its gonna ruin my day".
Just a thought.
Maybe a pm coming your way regarding the compEX course,doing survival Monday and would be interested to know a few more details about compex before I commit.
