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.
