Actually to be honest it doesnt' help at all in wet/snow conditions. The system works off the input of the various senors and some of them are for things like yaw/g's/and wheel speed. if the car is going straight it doesnt do anything. Also in very tight corners, i.e. autocrossing the system can get shut down and/or not handle the amount of power distribution it has to perform. The ATTS really shines on a track or in off/on ramps, places where the car is at the limit but you want more without crashing!

Don't get me wrong if I were to do it again I would get a base and go wtih the Quaife but I didn't and still never had a regret.

 

That type of driving is different from what I do anyway. I use my car in pretty much every day driving, so I'm not taking hairpins at 80 mph. Nor did I push the cars that hard when I tested them. I have fun with my car on curvy roads, sure. But I guess I'm not pushing it to that extreme. Guess if I had ATTS, I'd have probably never used it yet.

 

No, you definitely would have, just not notice it. You don't need to be taking 80 m.p.h. bends for it to be active, ATTS would work on a 30 mph tight curve etc. It's not so much a thing that's either on or off, used it or never used it.
