understeer

I'm posting this here instead of the suspension section because i'm guessing more people here will have an answer.

I recently put the ssc springs from zzperformance on my ls, it seems to handle quite a bit better for the most part. body roll was probably cut in half and it has an all around more solid feel, but through hard turns i'm seeing a slight amount of understeer. it almost feels like the inside front wheel is coming up to the point to where its losing traction and its pushing through the turn.

I plan to do a set of sway bars next, what would everyone suggest i get to get rid of my little problem?

Seriously...hover over the brake pedal with you left foot whenyou enter a turn and smoothly tap the brake...nothing hard or serious...should help out a ton

you said it sway bars, the rear specifically. putting a larger sway bar on will reduce the total traction of whatever end of the car it is applied to. large sway on the rear = neutral handling under throttle and oversteer if you lift off the throttle.

fwd isn't by choice, I wanted gm, wanted a car, couldn't afford a vette or solstice. its not like i had a lot of choice in the matter.

what swaybars work well? I think i am going to need a pair (heavy aftermarket in the rear and the little toothpick up front sounds like a bad match). I would like to get into a little road racing on the weekends just for fun, nothing serious but i do want something that can hold its own.

i guess i should do a search huh...

depends on what suits your driving style, how do you corner. early brake accelerate through, late left foot brake, late right foot brake? i have the progress rear sway with the stocker up front and that suits me, early brake accelerate through. the rear of the car continues to rotate under acceleration which is how i like it. if the car needs to rotate more just a slight lift off the throttle and the rear end comes around nicely. evaluate the way you tend to drive and use that info to make a decision based on data.

thats pretty much how i drive, concidering 95% is normal day to day driving the little bit of track time ive had with other cars thats the way i learned and it works well for me.

i tried the brake trick on a few windy roads in a parking lot today and while it does work its pretty tough to do, at least at first. it takes a very very light touch and is easy to over do. I to like it though, thanks for the tip,

jim, do you have an ls or ss? i'm asking so i know what front swaybar you have.

i have an ls, looking to get the adjustable front sway bar links to adjust it for when i race. one of the autocross sites i goto is very loose and a larger bar would help there, with adjustable links on a smaller bar you just add more unloaded tension and it feels as if you have a larger bar.

Besides doing a larger swaybar in back, I would look into getting a different alignment setup. That will help out in getting your car behave like you want it.
