I'm reviving this thread. My front brakes are completely shot and its time to upgrade. My issue is I need to know what kind of grinding id have to do on the back of my lc80s to make the 231 calipers fit. I'm not really wanting to run spacers but if I can get away with using 1/4" ones I'll do it for now. Just don't want to ruin my wheels mostly. I know the information is out there, and ive seen it all, but it's real spotty. Can someone give me the part number for the 231s. And I'm pretty sure using a 2006 tudra for reference will get me the right parts. I just gotta figure all this stuff out today so I'm in a rush. Feel like a no0b askin these questions lol.
