Seized piston (front brake) options

[SpeedIsProgress]

Hi, it turns out that the piston in my offside front caliper has seized. Since I'm going to have to replace it, my thoughts were to upgrade at the same time. Does anyone have any suggestions? Are there any other BMW calipers which will just bolt on but are better? Or should I look elsewhere? I will change the disks at the same time so this isn't an issue.

My car is an E46 (2001) 325i... 17" wheels.

Any advice appreciated.

Cheers,
James

the 330 runs bigger brakes and different calipers from what i can remember. you also need the carriers and all associated.

You could always look into refurb'd calipers, trading yours in for a nominal amount.
