Pavement Pushing Pig (understeer)
Pavement Pushing Pig (understeer) Is there any way to reduce this??
Here's the problem. I am currently monkeying with my suspension to try and get the back end more solidly planted when entering a turn. The only problem is that the better the behavior of the car coming into a corner the worse the understeer becomes, and the more I have to stand her on her nose just to turn in.
I know that these cars inherantly understeer, however, I would like to know if there are any other solutions other than loosening the rear suspension.

Re: Pavement Pushing Pig (understeer) Well I'm not an authority but to get this started you have 3 choices.
1. Brake earlier so you add more throttle coming out to lift the front end and transfer weight to the back end on the way out of the corner.
2. Move weight off the front by moving the battery to the back or a lighter hood or whatever else you can do.
3. Better/softer tires and more camber in the front.

Re: Pavement Pushing Pig (understeer) Car:
2000 WS6
Current Suspension Setup:
Firestone Firehawks R17 / 275 (on all four)
Global West Lower Control Arms (poly/poly)
HAL Shocks
Eibach Springs
Global West SFC (weld-ins)
Adjustable Panhard Bar (poly/poly)
Car is lowered ~2.5 to 3 inches
Alignment:
-2 camber up front
Neutral and centered in the back
I have been looking at my AC system affectionatly on the garage floor, debating on whether or not it is going to go back in.

Shocks set to really soft, but not all the way.
A 3" drop tells me you have Sportlines. WAY too little spring, both front and rear. Snag a set of G2 Super Springs. Combine that with G2 poly/rod LCAs ... trust me, you will love the feeling turning in and tracking out of a corner.

Re: Pavement Pushing Pig (understeer) definately trash the poly/poly control arms..
poly/poly felt ok when my car was stock ride height w/ decarbon shocks.. but then i lowered the car and put Konis on and the rear was really loose
poly/poly control arms make your rear-end handle as if it was on ice compared to poly/rod-end or rod-end/rod-end control arms
changing those arms will probably give you what you're looking for from your rear end... and then if you still have understeer problems you can adjust your front suspension or driving technique for the fix
all i do is autocross though(and i'm still new to that)... but, i can say that my understeer problems from last year are completely gone and it had very little to do w/ the suspension modifications i did over the winter(lotsa driver adjustments, they're free!)

Re: Pavement Pushing Pig (understeer) also try a heavier sway bar in the rear or a lighter bar in the front to help correct that.
maybe a slight caster ajustment, as well. Otherwise not so tight a turn in.
