understeer question

[Sboxin]

"So if I lift the entire car a 1/2" or so how will this change the handling?"

OK -- so you want to raise the car because of the poor street conditions -- that's all good.
When you raise the H&R's you will want to find a very good Porsche alignment shop/tech to reset both front and rear. If you can find a guy in Mass with a Biesbarth German alignment machine they may be your best bet to tune out some (but not all) of the understeer during your twisty road runs. If you keep the same tires - sound like good rubber - then you will always have some understeer (and that is a 'safe' thing).
You may not like the same alignment for the normal street/road driving. If you put a little front toe out in the alignment the car will turn into turns quicker but will not be very steady down the straight roads at high speed -- this is all a trade off

IMHO of course...

Edit: Also, if you put a GT3 front sway bar in the Boxster that may help also -- some folks do this for Ax, etc.

Also you could try 0 toe in back if you want the back end to rotate more easily. Toe out on the back will make it an oversteer like crazy and is not recommended. Rear toe in will add rear stability.

This is what I am going to do . I will start by adjusting the coilovers until I get some reasonable clearance . find a good alignment shop . see how that works out , hopefully before we get snow. then maybe some stickier rubber. I am getting the feeling that the pirellis don't have enough grip. Thanks everyone the info is greatly appreciated .

What tire sizes are you going with?
