Buy the Zimmerman rotors on Groton listed as part number#271788Z Stay away from the others except the OEM if you want to spend more money. Not really any difference. Balo and Brembo are now made in Brazil and Mexico and have had warping problems. In regards to pads, stay with OEM...more dust but less rotor wear and they do a good job of stopping. If in doubt, why don't you give groton a call? Don't know where the eBay seller (is it also Groton?) is getting the chassis number cut-off from unless they're assuming that chassis number has the 302mm rotors...Are you sure yours aren't 302? It's a bit hard to tell by putting a ruler up to them you know. Best way for me is to use a string through the center of the wheel well to the wheel well's edge and measure its length, then subtract the distance (twice when calculating both sides) of the string's distance to the edge of the rotor. Hope this helps.
