Default Upgrading to is350 front and rear calipers/rotors


I'm upgrading to the is350 front and rear calipers and rotors for my is250. I'm getting a pair of the larger front dust shields. Should I purchase a set for the rear as well. Will the is350 rear dust shield simply bolt on without any modification.

Also, should I worry about the shims? I'm planning to purchase some Hawks ceramic pads and thought they might come with their own shims.

Thanks in advance.

nice upgrade...i did the front but never seen the reason to change the rear...not much difference in caliper size....the dust shield should be about the same if not maybe a slight difference....you can probably shave off the piece that will touch..

Wouldn't really worry about the rear. As for shims - yes you would want to buy those.
