Default GS 300 brake caliper upgrade?
My gs300 awd needs new brakes all around BADLY. Can I install the 4 pot calipers from the 450h?

You can but you'll also need to swap out the rotors and the dust shield.

I just looked online, and the 3GS doesnt have front caliper brackets. It mounts directly to the hubs, and 06 hubs are showing that they are the same as 07-up hubs. So I think you should be fine with ordering calipers, brake rotors, pads etc.

If youre getting a better deal than $50.00 each for the calipers, because that is what they sell for on car-part.com

I bolted GS350 front calipers straight onto my 2006 GS300 awd, just had to cut part of the dust shield, no other modifications.

Arent the disc rotors a bigger size aswell? If they are I think you will benefit from more breaking power if you upgrade those aswell
