Slipping during high speed turns!?!?

i noticed a few times in the past when exiting the highway on the offramp and pressing the brakes normally on the turn the car slips when i had the brakes pushed. I first thought i might be the brakes which i replaced about 4-5 months ago. Then today i was drinving in the mall and came up on a curvy road at a higher speed (45mpg) and noticed the car slip but this time i wasnt using the brakes. the road conditions in this case were dry, dont remember the others. im thinking it is the tires. i replaced the rear ones this year, but never replaced the front and i think they are still the stock ones (michelin pilots) they do still have about 20% tread left so they are not bald. but maybe since they've been used for a while and there close to there end they do not perform well. anyone have any thoughts?

is the back slipping or the front, like are you overrotating or not rotating enough?

it seems like the front is slipping, the car basically loses traction and instead of turning the car would slip straight for a second until it regains traction. im not quite sure on what you mean by overrotating or under rotating?

It is called "understeer" - you are probably entering the turn too fast.

just throw some sway bars on you should be good lol, or go the cheap way and just slow down

no i dont think its because im going to fast. The speeds i am experiencing the slip at are not extreme, just higher speeds about 40mph on gradual turns. the car is essentially skipping and shaking when the slip happens, just like it would if it were wet out and you slammed on the brakes.

You could buy stickier tyres for the front, but as said above, go for good front and rear sway bars instead. If cost is an issue, the rear sway bar is the most important in reducing understeer and you don't necessarily need to go adjustable.

doesnt a 04 coupe come with front/rear sway bars?

Yes, all coupes do. But they're just suggesting that you upgrade to aftermarket versions, which can be adjusted to different stiffness settings, increasing or decreasing the slippage.
I don't know if that would help, but that's what they're talking about.

It's kind of difficult to pinpoint what the problem is, considering all the possible variables of speed, the degree of the curve you're driving on, how hard you're cutting the steering wheel, your tires, etc.

I'm going to say it's you're front tires. Your newer rear tires are sticking, but your front, worn tires are losing traction. Hence you skip and slide (understeer). RWD cars should naturally oversteer when you take a curve faster than normal, not understeer.

That's the problem.

vdc on or off doesnt address the real problem. just after i replaced my front toyos, i had slipping on ramps like you. those tires need time to burn off the crap on them so that was my problem. i suggest getting new front tires. if you look at your sidewalls, they're probably pretty worn down.

For the benefit of the thread starter:

I hope I explain this right
If the car is understeering (pushing), you should increase the size of the rear sway bar. A rear swaybar decreases the lateral movement (grip) at the rear of the car on turn in, which increases it at the front. This translates to more front traction for better turn in.
In my experience, upgrading the front tyres is really only a temporary fix to most understeer problems.

BUT..... as others have said, there can be many different factors that make a car understeer and behave erratically, so it's best to take it to a suspension specialist for a check up.

As I'm a noob to this forum I understand if the above info is disregarded

There's a strong possibility that the OP may be driving too fast for the particular conditions which he is referring to.

I trust that any thing he does to potentially improve the cornering ability of his G does not lead to a serious mishap.
