understeer really is a big issue on these cars w/ stock settings. it took me awhile to get my car dialed in so it would rotate instead of plow.

you mentioned trying to change the camber settings without messing up any other alignment settings. FYI, not possible. changing the camber on this car will change the toe. you will need to do a full alignment.

you should be able to get around -1.6 deg up front without camber plates or longer control arms. this is actually plenty for street tires. try -1.2 up front and -1.8 in back. zero out the toe front and rear. finally, run HIGHER tire pressures up front than in back (trust me on this). the RE050A is a decent tire; try 34F / 30R for cold pressures.

if you do all of this, understeer should not be much of an issue.

IMO, those who haven't had understeer issues w/ a stock boxster at the track are not driving fast enough. understeer quickly becomes the barrier to going faster, and is therefore a problem. reducing the understeer = faster lap times.
