it transfers torque not power. upto 80% to either wheel depending on the cars need. It will literally pull you round a corner used correctly.
atts to my knowledge is very solid and reliable.
there are less tuning options available but they are still available. atts is good to about 240whp.
atts gives the car a rwd feel with fwd safety. many is the time the rear will gently slip as i have powered out of a tight corner giving a massive grin.
Type S gearbox is close ratio and unique in the range.
understeer is a thing of the past.
atts is matched to a number of extensive suspension modifications that make the type S a MUCH more stable platform to corner from.
Type S has the best interior.
To get the same level of performance from a stock h22 would cost a hell of a lot more than buying a type S would nowadays. ask a1ex. his build cost as much as my car nearly and he was only pulling on me in second and i 17'' against his 15'' wheels.
People never seem to bitch so hard about the Nissan GTR AWD system which is funny because the same tech by the same guy is what atts is but in a FWD format. Designed After the AWD system as well.
Trusting people's opinions on why not to get a type S who have never driven one is like listening to a man who has never had a blowjob telling you it is a bad idea and taking his advice. Carry on by all means but you could be seriously missing out.
The ''I know what I like and I like what I know'' attitude is weak as three day old jobby.
Having driven stock 5th 4ws, modded 4th 2ws lsd, stock motegi, and three type S's the type S is the way to go. My points are based on personal experience and opinion but I defy anyone to contradict any of them with serious data.
Yes there are 'better' system available now but not in the class of car we are buying and owning.
give it a try, its not for everyone but it makes for bloody fun driving. There is a reason that the type S was and still is near double the price of the next best option.
@newkid: you are exactly what I mean. you have no real knowledge of this subject and every line you write hi-lights it in bold caps.

atts light comes on if you have a light bulb out. its an important system and so is having all your lights working while on the road. This is called a 'warning light'. Its to warn you that something is amiss and you should have a look, untill then no atts. Rather like TC light or 4WS lights come on on other models

I have never actually known an ATTS system to fail. My own and rattys issues have been caused whole and complete by US frigging about with wiring and messing where we know not what we do. If you can find a uk member with a damaged or broken unit in the last 5 years I will be impressed.
Im not defending the type S here, I dont need to, it can look after itself fine. I will defend against opinion based on ignorance and conjecture though, rather like I would shout down a guy who had never felt the inside of a womans mouth but yet was shouting how awful it must be to put your gentleman's sausage in there.
