ok, i've had enough of this shit. As most people already know, i recently bought a set of rotors for the front and rear for the sportivo. the ebay listing and the aftermarket sites all say that the sportivo take the SA diameter which is 258mm. well guess what? i tried to get them installed today and they aren't the correct size. they were clearly smaller than the current rotors i got on. mechanic said that they didnt sit flush on the hub. so off they went and now i'm going to order the japanese diameter rotor and fit them on nex weekend. to further add to this, there was a mate who had his changed to RDA gold rotors a long time ago and he said that his mechanic told him the rotors are smaller than the OEM rears. so he "had to get it custom made" to be fitted on the car. This "custom made" is actually just the same size as the japanese rotor. another story i heard was that a former member on this forum redrilled celica ZZT231 rear rotors to fit on the sportivo as they share the same size (just not the stud holes corolla has 4 celica has 5) the size was also 269mm. and this explains why the rear pads on the celica are interchangable between them and the sportivo. also says on the box as well. this clears it up now and i'll be sending emails to the aftermarket companies to update their information so no confusion is to be had again in the future. i'll also update the corolla faq just in case people want to know what brakes to get. FYI - the pads are of the aisin type. not the sumitomo. however when i removed the TRD blacks on the rear it said "sumitomo" on them. don't ask why. that is all, thread closed.
