Push

[StevenMosley]

My car has a problem of pushing.

If nothing else was changed other then the strut settings what would
reduce this?

harder in front and softer in back? Or the opposite?

[aansorge]

Yeah, just the opposite. Go soft up front and hard in the back. Otherwise, play with tire pressures. I bet you can go pretty low up front with that car to get more grip.

Remember....Before you get too nuts with trying to loosen up the back, make sure you do everything you can to the front first. People sometimes respond to a problem like this by taking grip away from one end, when they should really be trying to *add* grip to the other. Have fun!

Jason Burkett at www.paragon-products.com has a nice chart about how different settings will affect the car, from shocks to springs, to sway bars to tire pressures. I keep a copy in my auto x tool kit just to have for reference.

Is the car just pushing at turn in? Or is it a steady state condition? If it's steady-state, I doubt there's much you can do with the dampers to correct the situation. My car developed a push earlier this season when my victoracers got heat cycled out.

just random thoughts.

The problem is at turn in.

It has KYB AGX sturts that are considered to be very stiff.

Here are the results I have had so far.
(1=softest 4=hardest)

Valley Fair:
F: 1 B: 4
Lots of push and the front end was skipping over broken pavement.

BIR:
F: 1 B:4
No push at highspeeds, but car still had bounce on uneven pavement.

All Right:
F: 1 B:1
A little push turn in push and a lot of on throttle oversteer. Bouncing
was gone.

Saint Cloud
F: 1 B: 1
A lot of push in the 5-110 degree plus corners
F: 2 B: 1
A little less push
F: 3 B: 1
Minimal or no push.

I am really having a hard time understanding the logic behind the shock setting and
the way the car handles. I guess I am to the point that I will just have to keep playing and go with what works.

I think what you're also dealing with is a difference in surfaces...and the unpredictable change in handing from one location to the next. MOST cars can be tweaked to handle "perfectly" on a given surface but change the surface (dirty, wet, poor surface) and it's all down the drain - they don't STAY neutral. In my experience (with the cars I've owned) it could be spot-on and add a little rain and I pick up a push. Or go to a "dirty" location and pick up a push. I'm not sure about the typical FWD...if they usually go the same direction. It's true that softening the front of MOST cars IS the correct direction to go to cure a push....UNLESS as a result of softening it, you have introduced excess camber change and now the tires CAN"T work as well...they're on the sidewalls. So nothing's a 100% sure thing. Also there are some passenger cars that have so much chassis flex they CAN't be totally sorted out AS DELIVERED...( for a "stock" AX class). Throw in the variables of tire pressure , driving style and even aerodynamics at high speeds and no wonder we have trouble getting these lumps to handle decent! You might have to learn how to adjust for every event where the location and/or conditions change. Hey, if it was easy, anyone would be doing it! ;)

is this on the MR-2 or the Datsun? the datsuns are known to have very little wheel travel, so combined with the lowering springs, you could be hitting bumpstops and then you're illin'.
mr-2; i don't know nuthin but what alreadys been stated.

[Jon Kotek]

I run AGX on the Miata, I normally run the back half as hard as the front and that keeps the push down, however you gotta be careful because the tail gets happy at that point also.

Also mine have 8 settings vs 4 for you

It is the MR2. It has been a challenge to figure out. I think it is because the motor in the wrong place.

The Datsun doesn't seem to care what you do to it. At the all right event it was toed in about a half inch. It drove fine, but the thing chewed up the tires pretty bad. Maybe that is why I didn't have a single clean run in it.
