ok seeing i just sold my grand am and my jeep cherokee i am on my way to start my type s fun.... so i am looking at a few different engines.

now some are offering hydrolic lsd or atts as a no extra cost.

what are the pro's and con's of each of these ... cuz im not sure to tell u the truth.

ur opinion would be greatly appreciated

 

I'd go with the mechanical LSD over the ATTS. The ATTS (Active Torque Transfer System) is a hydraulically assisted, computer operated power transfer system which compensates power to each wheel when turning. All I've heard, and it makes sense, is that it's limited in what it can do, and generally, doesn't work at ALL speeds. The weight issue is nonsense, so don't even ask about it. A mechanical LSD (Limited Slip Differential) is what you find in all rally cars, and all real sports cars. The LSD mechanically opens and and closes to transfer to the wheel experiencing less spin more power, so as opposed to an open-differential car, when one wheel spins, instead of that wheel getting all the power and continuing to spin, the LSD transfers power to the wheel which has traction (or more) and you're off. My 2 cents, by the way, congrats on getting rid of the american trash, welcome to the new world

 

basically what he said. atts kicks in more at higher speeds. like stated above, it is limited. after you reach about 240 whp, it basically disengages itself. i have atts, and i enjoy it. I would recommend LSD instead due to ATTS drawbacks.

what do you plan on doing with the car mechanically and physically? that should answer your question.
