I too switched from the Bridgestone RFT to the PS2s and initially I noticed the squirm due to sidewall flex and newness of the tread. You won't experience the full capabilities of the PS2's until you find the optimum tire pressure and scrub the tires in for 100-500 miles depending on your driving style. After you do this, you'll understand why the PS2's are so highly rated. I've autocrossed them and my only complaint is the treadwear rating, but the new PSSs should fix that.

 

damn thats a big fuckn bill for tires!
