Well, let me think about it real hard. I have a strange hunch it will not fit on a IS250.

You could always upgrade the whole brake system... But then your talking a lot more money...

Anyone know how simple this is, is it more or less a direct swap or more involved?

seems easy but i think the parts alone are extremely pricey

OEM parts are usually very expensive. The biggest question is whether the mounting brackets for the calipers are the same on the 250/350. If they are, then it shouldn't take longer than an hour a side taking your time (if you've done this before.) If they're not, then custom brackets need to be fabbed and then you would be better off with an aftermarket bbk.

Not only that, but the fluid volume is different, so the ABS won't work right unless you swap it too. Stoptech has a great white paper on their site about this issue. It's just not as simple as sticking a different caliper on an existing system and having it work right.

Yes just keep your stock brakes. . .
