after reading this and the other thread, it still sounds like user error. i've driven 240's with bad suspension, alignment problems and all that. its still pretty easy to get'em sideways.

If you are trying to... if you are driving grip style it is easy to make the car understeer, just the same as it is easy to make the car oversteer.

In both instances the driver is at fault. The driver can almost always remedy understeer or oversteer by their driving style. Odds are the above mentioned driver is coming into the corner too hot or being too aggressive with the controls. It's hard for anyone to say yes or no since we weren't there.

BTW, 14.5Drift you are an amateur driver, just the same as everyone else on NICO. Never rule out that your driving isn't causing the problem, cause about 7 times outta 10 thats usually the case. Since your car is not adjustable, you must become the adjustability. The sooner you realize that you really have no grasp on actual correct performance driving technique the sooner you will get better. I say this because I myself am trying to learn how to drive properly, and by shutting out others you only learn from mistakes which can easily cost you money, your car, or your life.

bah!! your all wrong!! it must be the car !!!!

lol

Of course I have tried to adjust my driving style, but ultimatly I just didn't want to, so I sold the car. Found some thing that doesn't require me to learn how to drive all over again.

I also must remind, that in the instance of the accident it was not me driving, it was my friend who is 35 years old. Still not sure if it's working for or against him though, he could be old and wise, or just old and slow, lol. But the problem of understeer is not only apparent to just me, but the new owner who has found this understeer to leave a bad taste in his mouth too.

It is just kind of wierd, the car will handle so well in the high speed freeway over passes, I'm talking a cool 85-90 mph through those suckers, then when you expect the same grip in the twisties it is like you only get 1/2 half of what it is capabilities. The front damn end just won't stick.

I dont know what, oh well right now I am runnin out to check the bushings, report what i find later

Yes, but the location of the engine is stricly a means of achieving a desired weight balance.

The designers feel that 40/60 is the best weight distribution for rwd performance

The car has a slow loading of the suspension on the highway... cause of the slow turn of the corners. In a tighter corner weight shift can cause more problems, it is also easier for an inexperienced driver to understeer a car rather than oversteer it because typically people are scared of oversteer situations because they feel more out of control.

The number one driver related cause of FR understeer is entering a corner too fast. If you overcook the entry apply slight brake pressure to neutralize the car, it's called trailbraking and transfers weight to the front of the car to help the front tires to grip. It also can put the car sideways if you brake too hard.
