How does your Slingshot drive?
I did a couple of track days when it was still a trike and it was better than I expected. Very neutral and easy to throttle steer if needed. Fun to make it over-steer with throttle too. Some guys with data recorders were measuring 1.1G in the corners, and that was on shitty stock Kenda tires..
I haven't tracked it with the quad wheel setup but I can tell it's going to be even better. It corners harder than anything I've driven so far. (*) It hangs on so well that I'm afraid to get it into a high speed drift on the street since I don't know what it'll do when it does break loose. Will find out next month on open track day. Only complaint is the crappy electric power steering which is numb. I installed a switch to turn it off when on the track or interstate driving.
It makes any trip to the corner store a fun event instead of a chore.
BTW, is that Volvo Canadian the same as an 1800? I lusted after those when I was around 20.
(*) Edit: Except for my Kart (125 Rotax class) that corners at 2.5G
