I've got everything installed according to the instructions and all's working fine. I had a first test with a GT40 Mk. IV (what else ) and yeah, unless one of my quaint medical quirks plays up, I'm definitely in. Lots of practice ahead because I want to test every single one of these -unknown to me- cars. As such, it's way too early to mention times.
IMHO a random grid without qualification shouldn't be a problem. The Targa isn't *that* narrow and there are plenty of overtaking opportunities.
