Laugh! I'm way ahead of you 99sel.

Already putting that together for my b14. Once we perfect it, I will probably be selling some as well

Have you checked the toe on your rear wheels? When I drove up to VA (12 hour drive) to get my rear beam bent, Steve discovered that my right rear wheel had toe out and my left rear had no toe. Apparently this was basically a factory defect. You can imagine turns were a bit squirrelly at times. Luckily a guy up there had a parts car that had a good beam and I gave him some money and we swapped them. I am definitely going to have to agree with Old Guy on this one, get your rear beam bent some how, some way. Drive out to CO sometime and get it done. It will definitely help a huge amount.

It certainly doesn't sound like your car is behaving normally. Is it equally as bad at understeering in both directions? Regardless, here's what I would do if it were my car...

1. I would start off with a good alignment to make sure nothing is bent up front.
2. I would check to make sure none of the bushings that were replaced were binding... especially the front sway bar bushings, also try taking off the front sway bar.
3. I would corner weight the car.

My guess is that one of those 3 will reveal the culpret.

Should all those check out, then you'll have to start taking the suspension back to stock to find what was causing the problem. Start by removing the rear brace and sway bar. That should induce more understeer. Does it? All of the other changes mentioned in this thread can help tune a suspension, but you're not looking to tune it, you're looking to figure out what is wrong with it. I wouldn't try to mask the problem with sway bar, bent beam, tire pressure, tire compound, or other changes. Get to the heart of the problem, fix it, and then use these adjustments to fine tune your suspension.

Dre said it pretty much.

So you are wanting to get rid of oversteer? from what Ive seen by youre setup ( totally disregarding how well you can hook up)... Dre went into a lot of detail with the tire size and its effect on handling, very insightful. Also take in consideration tire compound. For example general rule of thumb in autocrossing when going from street compound tires to R compound you should easily pick up a couple seconds once you are up to spec on the new tires.

You have the K sports, im not going to bother bashing or praising but instead give you the most practical bang for the buck advice, and maybe a proposition.
First and foremost... Kill the understeer. I am a big fan of stiffining up the chassis. We all know these struts are stiff ( And I am LOVING the new struts that i put on mine this fall.) But those rear springs got to go. They are a joke for performance. I am running 7kg/mm springs on all four corners... roughly in the 400lb area off the top of my head.

If you want look up and see if the K sports and D2s share the same springs. I can dig around for them but I know I have a set of 9kg/mm springs ( 500 ish lb/ in springs?) laying around in the garage. Get those suckers on and shizzam... instant oversteer.

My point of view is... The more oversteer the better... there is too much but hey, look what we drive. understeer is our inherent enemy in the handling game along with the busload of other issues that I dont want to go into. Ill take all the oversteer I can get, as it really suits how I want to drive. Hope I shed some light on this. Good luck. dont be afraid to try something. I think springs are less than 75 a pair from D2. Gotta love the world economy.
