so, McMark and i spent all day today trying to corner balance my tweaked and twisted tub.

i started out with all 4 corners the same ride-height. but the car felt awful. twitchy like hell and the left front always wanted to slide on me.

so, we got a bunch of scales and went to investigate.

almost 3/4 tank of gas and my fat ass in the drivers seat ...

the end result is still not perfect, but *much* better than before.
interestingly enough, now that the corners are balanced, the tub looks all crooked. (IMG:style_emoticons/default/wacko.gif)

i guess it makes sense, it's either:
- twisted tub, same ride height on all 4 corners, corner weights waaaay off
or
- twisted tub, corners balanced, tub looks bend.


we'll see how it holds up at the AX this AM, but it felt *much* better on the ride home from napa ...

thank you Mr. McMark!

Yeah, a nice set of scales from SMART is on my short list.

I had a good time and learned a lot.

Tomorrow morning we'll see if it was worth it. (IMG:style_emoticons/default/driving.gif)

well, what do you know? for some reason, we got it "dead on"! (IMG:style_emoticons/default/smilie_pokal.gif)

weird bump-steer and random lane change is gone. it felt really nice on the freeway on the way home ...
then the AX today, well, what can i say, the car handled great! crisp turn in and perfect balance. even the (more or less random) sway bar setting was dead on. just a tad of oversteer, which is gud on a guttless 1.7L. felt like i had power oversteer, helped a lot in getting the car around those tight turns ...

i was only 3 secs of trekkor, which was plenty good enough for me ...
