reverse your camber from F to R.

Do this before you put in the rear springs...

This alignment is staying till spring. It works ok. Tire wear is dead-nuts even. I'm not spending $100 on a service yet and I'm not eyeballing it either. In spring I'll get it with different specs and corner weight the car :makeout:

Plan for the weekend is to trim the front sway bushings till that bitch spins freely and put fronts to full soft. If that does it great. If not I'm installing the springs and putting the front sway into hardest setting.

Set the tires to where they wear well.
Set the alignment where the car works more or less.

Dial the rest using shocks and sways.

You say low speed understeer? In a constant radius corner? Reducing radius corner? Increasing? Do explain.

The car won't turn, or, the car won't rotate? As in, the front tires don't feel like turning, or, the front tires turn, but, the rear is dragging the entire car past the turning point?

Details, details...

Front tires don't feel like turning. Constant radius turns, any 90* turn in second gear basically.

I grinded the front sway bushings. It was definitely binding before, now it rotates freely. Also full soft on front shocks. Made a big difference, but it still not quite there. I think the 400# rear springs may be overkill, but we'll see. They'll get here middle of the week. Going autocrossing on the weekend so I'll try it out.

Also, thanks for spoon feeding me.

that might just be all you need. Honestly, when I first got my Teins I was looking for new rear springs before I even put them on, something like 4.5K over my 6K. When I calculate my FRC current, it's around 49% so I thought the car would have a tendency to oversteer.

Once I got them on, I was actually surprised that the car felt pretty damn balanced, I liked that it had a little tendency to oversteer, but it's not tail happy. But the rear will let go before the front.

I had 400/250 previously on my konis and it would push like crazy. (56% FRC)

In fact, when I had to replace my rear springs anyways because of coil bind issues, I stuck with 6K. Your 440/400 combo with that front bar puts you around 53% FRC over 60% you have now, so you might be happier with the result.

Drove some more today, car is a lot better. Now the front tires squeal like pigs instead of simply sliding/plowing/scrubbing speed.

I used to have the same setup on my 96 but with the stock front sway. Something like 53% FRC. One cold lovely morning I was going around a fairly mild turn. Rear end started to slide out. I panicked and lifted. Car snapped around and then I plowed through someone's wooden fence and then about 100ft (or more?) of their front yard.

comme ca

So needless to say I'm kind of scared of low FRC. a) I didn't know about "don't lift" thing b) I had shitty all seasons (biggest problem, probably) c) I didn't buy the front sway yet.

Needed to be moar like this guy -


So right now I'm at 60% FRC and with the 400# rear springs should drop to 55-54? Anyways the calc is a bit broken because I can't set sway length and that shit matters.

Will report again once the springs arrive :loser:

that picture is scary to look at :/
Just curious, what other tire pressures have you tried? and what are their effects?

sjmarcy 07-24-2011 08:32 AM

More trailbraking would help a ton, on brakes that allow a great deal of it.

soviet 07-24-2011 10:54 AM

Yeah I got very lucky in that accident - missed a utility pole and some trees. The big dark chunks in that picture is actually a big trash can. It ended up in 3 pieces - 2 on the ground and one up in a tree....

I have tried 28-24 psi. I want to keep pressures same all around to keep it simple. Last night I put in the 400lb rear springs, put the front sway to full stiff and shocks to full soft all around. FEELS GOOD MAN.

Didn't drive it too much yet though so can't fully describe it.
