well listen to the very smart man that brought physics into it! he is 110% right! its just physics there isnt anything wrong with your car. its just centripital force like swinging your keys around on a string. the faster you spin them the bigger the circle gets thats all.

like on of the other guys said right after that he learned it in a driving class. i have experienced it in many cars including front drive and even in my dads vette and grandpas vew caddy. no tire screeching or anything like understeer just a bigger, wider path. i wouldnt pay much attention to it at all just have fun in the car and take it to a track and find out how far you can push it to find out what it can really do.

This statement is not necessarily true. And again, it's just simple physics.

Now to the reason why the Prelude that you drove reacted differently. There are just too many variables that can make this happen. To name a few, suspension design, tires, weight of the car, and road surface. Nobody can really give you an answer without having experienced what you have experienced in those cars.

Take this as a grain of salt, because I think there are a lot of incorrect information in this thread regarding understeer, LSD, tire, etc. There is a fine line between understeer and the car "pushes" due to the law of physics.

Interesting.

Maybe this is really simple. The turns you notice this on are all covered in a nice film of road grime and oil.

What are you running for tires?

The Type-SH is because of the ATTS LSD-like system. In the end, it is still a FWD car.

Like I said...go take some driving classes so you can learn how to make the most of an amazing RWD car like ours.

Some good reading for the OP. http://turnfast.com/technical

2 things....the way to accurately compare the cars is to go into the same corner at the same speed and don't accelerate. Addig throttle turns this into an apples/oranges debate. The physics of being pulled through a corner by a front-weighted FWD and being pushed through by a mid-engine RWD (yes, the S2K is technically mid-engine...weight is behind front wheels) are not comparable.

2nd, on a more simplistic note:
1. Go get your car aligned. Honda factory alignment on the S2K is notoriously bad.
2. Set your front to 33psi and your rears to 31psi...you will feel the difference.

Please consider the OP states he is nowhere near the limit of grip, so real understeer should not come into play here.

My AP1 would _tighten_ the turn on the throttle under similar conditions, a bit closer to the limit, because of the rear wheels changing toe under rearwards weight transfer. This should not be the case for an 07.

The LSD _will_ cause understeer to an extent since applying torque increases the locking force, and rear wheels that are forced to rotate at the same speed will rather go in a straight line than around a turn.

My bet is that it's either really the LSD or a faulty alignment, which is unlikely at low mileage if the car has never hit a pothole or similar.

The OP seems to be quite sensitve to how the car behaves, which is good. Transitional handling is one of the defining characteristics of how a vehicle feels, and investigating it is a great exercise.

Have fun & stay safe,
Marin

I tried, and I can reproduce this with my AP1. It's actually quite pronounced once you look for it. The effect was probably masked by the "bump steer" I used to have before I fitted the anti bump steer kit.

Still, it's nothing to worry about. I still think it's the torsen diff btw.
