Default F-sport rear bbk install...caliper bracket wont fit. What changed?

Just like the title says. Tried installing my rear f-sport bbk and the brackets that go on the hub don't fit properly. The spacing on the holes is almost too close together and the bracket itself seems too thick to fit between the rotor and the hub. Other then the positioning of the caliper does anyone know what has changed on the rear setup? I will call Sewell in the morning and then Stop Tech if I need to, but I was wondering if anyone could shed some light on this...

the rear brakes on the 3IS 350 are different (bigger calipers) than the 2IS IS350. It almost looks like they are using 250 front calipers on the rear of the 350

yes the caliper is different, got my 3IS on thurs, been doing all kinds of comparisons with my 2IS. Its nicer they put a bigger caliper on the 3IS rear, the 2IS rear seemed puny

You're right that the rear caliper is different and so is the hub. However, it is the same as the 2013/2014 GS350 RWD and Stop Tech makes a kit for that car...so I have ordered the mounts for that kit and they should be here tomorrow. I am crossing my fingers they work.

Side note, Stop Tech were a bunch of a**holes helping with this...Sewell was great.

Update for anyone who is interested...I got the rears to fit by ordering the brackets for Stop Tech's BBK for the 2013 GS350. The caliper on the GS and 2014 IS are exactly the same, so the bracket for that kit fits perfectly. The calipers for that kit are the ST60 and ST40 as well, so the caliper fits like it should. For those that are interested in the part numbers, PM me and I'll pass it on to you.

Still waiting to see how Lexus & StopTech are working out those logistics..
