Sorry, I left the toe setting off. I do have a bit of rear toe in. I'd have look at my records to see how much, but it's basically in the middle of the recommended factory settings. It's definitely not twitchy, just pushes everywhere.

I think I may just throw on the 255s without changing anything else. If it's to loose I may be able to calm it down by increasing the AOA. I am still tempted to try the eibach bar since I already have it and the soft setting is not much stiffer than the stock '03 front bar.

Yea, I'd recommend you leave everything alone and add the 255s up front and see how it does. Do you have slow speed (<60mph) push too? High speed push can definitely be caused by too much rear wing. Is your wing contoured? If so even flat it will produce downforce.

Yup, just leave the car as-is. If you take off the wing while going square with your current spring rates, it will oversteer. I'd just test it as is and adjust by playing with your sway bars. You can go stiffer on the front and disconnect the rear.

Plan for next weekend:

KWv3 with original springs
Eibach front sway bar, factory '03 rear bar
-3.5f camber, -3 rear
255 square NT01

Will I have excessive oversteer? Seems as though most run heavier front springs (compared to rear) and a very large front bar for 255 square.
My take is even going flat on AoA will make u push big time. Add a nice big front splitter

I don't recommend going any larger than about 2 inches from the bumper. I tried a very large splitter and I gained over a second a lap when I finally trimmed it to 1.5 inches to meet the Honda Challenge rules.

Which wing? GTC-200? Any risers?

My local track is quite fast, min speed through the slowest turn is ~65. Haven't tested the wing anywhere else yet, but will soon.

Kognition... it's a beast

I'll add a front splitter after I get a new (lower) trailer.

Is there anyone who actually runs both non-staggered tires and springs? The posts I've read all indicate you should run staggered springs AND a bigger front bar.

I actually meant Rob (as curious how big of a wing he was using when he found 1.5" splitter to be optimum).

But re you: I run non-staggered tires (255) and springs (16k f/r Tein SRC). I run stock sways. I ran the car with NO wing, and currently with just a CR wing. Alignment: -3.4 f/r, 5/32" toe-in. The car does not have "excessive" oversteer. With the Kognition wing you DEFINITELY will not have excessive oversteer!

Run the car as-is and go from there. I imagine it will still push heavily in high speed sections, and with a min speed of 65 you are not going to have the very low speed sections where oversteer would be more apparent.
