I'm not sure about any one else, but I've had a terrible time getting parts for my GXP. I've purchased various trim items (granted this probably isn't very common), all the way to normal wear and tear items.

So far out of 15 to 20 items I've purchased, all but one has come from Lansing MI.

Today I was looking for front brake parts since I'm putting new pads (Ceramix) and rotors on the front. I wanted a brake hardware kit and nobody can supply one aftermarket made for the GXP. Worse yet, the only way it is available from GM is with the pads. Even when I checked on pads, they told me they would be coming from the US.

I've checked all the common places such as NAPA, Part Source, Canadian Tire, Auto Value, etc. I've had the same information from everyone.

Starting to get really frustrated

Sorry to hear about that. Hopefully I won't have too much of a wait when I need parts since I am in Michigan. Good luck on the brakes!

Well you parts guy has no idea then...

for rotors front Caddy seville and I believe the calipers are the same I think the rears are 11.25 inch i'll have to look at an old post.

These are the ones they got for me, but aren't the same as what'* on my car. The boots are totally different, and the channel in the retainers is too large. Raybestos was one of the companies they contacted. These are for the non-GXP Bonneville.

Just to add to the confusion, when I contacted the dealership they needed my VIN. They said for the '04 GXP there were different parts which can only be determined by the VIN.

most other parts transfer over to the caddy.

Thanks for the info. This may help in the future. I reused what I had this time since it was all in good shape. I just checked for tears or problems with the boots, cleaned up the pad retainers and cleaned / re-lubed the guide pins.

Time to test drive these new Ceramix!
