They are great, a huge improvement over the old discs I had on (no idea what they were though) Gave them a pretty hard time on the alpine cruise a month ago, boiled my brake fluid but the discs are still in good shape, no warping at all But I have heard you can still warp them if you are really aggressive on the brake pedal, If your going to be doing power plays and some really high speed stops with them I would say the T3's would be better But overall I have no complaints and T2's are a lot cheaper than T3's
