Ways to decrease oversteer on an ED6 chassis?
I figured I'd get the best and most knowledgable responses if I posted this here, so here is my question...
I have an 89 ED6 chassis (originally a dx auto tranny) with a stock DA rear sway bar setup (using modified mount positions to bolt onto the dx chassis), a stock si front sway bar setup, new poly bushings on everything, tokico 5-way adjustable shocks mated to some hand-me-down skunk2 sleeve type coil-overs (all I could afford at the time, a little bouncy for my tastes though), and recently because of some bearing issues a set of DA front spindles. I had the car corner balanced and aligned (but kept around -.5 degree front negative camber and -1 degree in the rear), but it seems to have quite a bit more oversteer than I really want in the setup. Now I realize alot of the problem stems from the DA spindles, but the handling of the car has increased almost 2-fold over the previous setup. Would increasing the size of the front sway bar to say a stock DA size bar (which I have and is considerably larger than the si bar) possibly aid in reducing my oversteer? The car is very responsive upon entry into a corner (perhaps even a hair bit of understeer while braking up to that point), but once it reaches the apex of the turn it feels as if the front wants to keep turning and the rear wants to slide out. Any suggestions? And thanks guys...I appreciate your time!

The last time I tried running the DA front bar (on stock ED spindles) I had massive amounts of understeer and no body roll. I had to adjust the dampers to there softest setting just to induce some body roll to counter the understeer. I'll probably try swapping it back in sometime this weekend or over the next couple days and set the shocks a hair softer again and see where it gets me.
