New Understeer Problem

[Topless]

A little background first:
98 Box 2.5L, 75k miles, tires PS2's 225/45/17Front, 255/40/17 rear, performance alignment Camber -.7 deg. Front, - 1.4 deg. rear, zero toe front and rear. Two years Auto-X / track experience.

Last year in Oct. my rear tires were down to the wear bars, lap times were suffering a bit and I had a few spins on corner exit with snap oversteer on rough surfaces. The tires were actually 4 years old and I figured the rears were toast. Front tires were only 1/2 gone and still felt ok. I put new PS2 rubber on the rear and added a lower stress bar to reduce chassis flex. Now the rear of the car is completely predictable. I feel I can put the rear exactly where I want it with my right foot and no surprises. I am carrying higher speeds and some high 2nd gear turns are now moderate 3rd gear. So far so good.

The problem:
Now on downhill off camber turn in's and carousel turns she plows like nobody's business. I feel like I am crawling through these sections. Even if I really pitch the rear out the front just howls through. I am turning faster times. It just looks and feels really stupid when it plows.

Possible solutions:
A. Learn how to drive.
B. Lose those front tires cuz they're 4 yr old hockey pucks.
C. Add a front strut tower brace to balance front/rear chassis stiffness and precision.
D. Fine tune the alignment.

Anything I am missing here?? Your input is appreciated. The more track and Auto-X experience the better.
