Excessive stock understeer can be fixed on the cheap by the old shadetree autocrosser trick of beefing up the rear roll bar. Just use two cable clamps on each end of the center section of the stock rear bar to clamp on a similar short length of bar. I cut the ends off of an old stock bar from my Accord and used it. This is a fairly limited trick, but it sure is cheap! Careful, you can get too much rear bar and go into oversteer this way.
