I put the Zimmerman Crossed drilled front and rear on my T-5R. Zero Problems after 5000 miles. I got them very cheap from http://www.eeuroparts.com/ Call them and talk to them. Do Not order online! I used stock volvo pads with the shims on the rear. And yes, it does matter which way the arrow faces on the rear shims. Violent shaking otherwise. The main and most important thing in preventing warping is torque your lugs in the correct pattern to exactly 84 ftlbs. And yes, if you try to do this yourself to save $20.00, you are being cheap and sacrificing your own safety as well as the rest of us who might drive near you. Also, if you do not like noise from your brakes, do not use cross drilled. They make a somewhat loud whirring noise when braking due to the holes. Good Luck in what ever you decide....
