Wow, is all i can say, the damn thing pushes like a train. I have about -1.8 camber, tires are 555s set at 30psi, the frt and rear sway are 1lE have G2 springs and Hds. can someone give me basic pointers on what to try.

Thanks

A push typically means you have too much rate up front or not enough out back. Rate can be springs, sway bar or even shock valving.

Where do you see the push? entry, mid or exit? Don't say "everywhere".

A rule of thumb that has helped me in most instances is a push/loose when entering the corner means I need to address the front rate and a push/loose on exit typically means to address the rear rate.

Mid corner typically is shock/spring interaction as the weight transfers. It either transfers too fast or not fast enough.

Finally, if you can solve a push by entering the corner slower, you might need to adjust the roll rate on your right foot.

1. First Slow In, fast out!
2. You could benefit from bigger sway bar in front.
3. I would try 35psi in fron and 28psi in the back and see how the car responds that should give you a bit more oversteer.
4. I'm suspecting that your shocks may be playing a part into your problem too much spring and not enough damping.

LOL Mitch I guess you beat me to it on the last point!

Listen to Mitch! we could suggest 100 things to do but until we know more specifics it will be hard to pinpoint your problem.

Push in, mid and exit is pretty good. I can clutch kick it and get it bak around. But turn in is nasty. I have played with tire pressure from 22-36psi and found a happy point. The "push" starts with a slow speed turn in. i mea 60-70mph turn in. Nothing crazy. I guess what i am asking if i had swaybars should i go larger 1st or do both frt and rear.

So does a little tap on the brake pedal help the front plant or does it just skate across the track regardless of what you do to help weight transfer?

If it's nasty on corner entry and then all through the turn, I would first suggest you are carrying way too much speed into the corner.

Typically, a car that is close to balanced, will push at one point but not all 3. Remember, entering the turn, you are biasing the weight forward (braking), mid turn is a weight transition (brakes to throttle) and exit is weight rearward (full on the gas).

Saying that the push is everywhere tells me you are pushing the car too hard into a corner and the tires never have a chance to recover.

2 things to try to alter driving style.

First of all, brake just a little sooner and try and roll through the turn and see what the results are. If the car rolls through the turn with relative ease, then your entry speed is too great.

Second, try lessening steering input to reduce the tire's angle of attack and regain some side bite. This is a tough "mind over SOTP" step. When the car isn't turning already, turning the wheel back just doesn't seem right.

Pressures ... you have gone to extremes on pressures, settling on one. Do you have a pyrometer? Need to get one if you don't and keep detailed notes. Being able to replicate settings is an important part of suspension tuning.

A wide variation between front and rear pressures is a band-aid to a greater problem. It's a quick, race day fix, but not a solution. My tires pressures are pretty much square all the way around. Wear is more predictable and handling is linear as the tire grows in pressures.

I am seeing less than 10* difference in tire temps across the face of the tire.

To address handling on race day, a 1/2 pound of pressure can make the difference.
