AP Disc replacements????

Lee13 · 12-12-2009, 04:39 PM

Hello guys I need to replace my AP discs on the front. Pretty disappointed with the AP ones as they still look like they have loads of life left in them but at Cadwell yesterday they were humming like buggery then started to warp with more heat. I left them to cool and the warping went but the terrible humming noise is still there. Any suggestions???? I'm also thinking while Im on to buy some bells for the rear and change them from the standard CSL discs. I have the AP calipers front&rear. Cheers guys

cant do it

performance friction are the only rear set up that comes with a separate bell, the AP are the same floating disk as the OEM disks. Most people seem to put the PF disks on the AP front alloy bells when replacing the AP disks

Will the front AP's not take a light skim Lee from your locally friendly cash job engineering firm?

I will probably do that as a matter of course. I just don't want another trackday cut short next time round. It's got to be worth a try for few quid. Cheers for the thoughts
