when you changed the discs last time did you clean the hubs down good? with a wire brush? also cheap discs do warp quick my 288 front discs lasted 5k now there warpped they were just gsf discs,pads, il be geting some ebc turbo discs when i can afford some
there not drilled as ive heard many people moan about drilled discs as they crack
I'll give them a good clean when I fit my new discs. I'd be happy if mine lasted 5k

. And nah. Not into drilled

think I'm gonna buy some plain ebc/brembo discs from badger5 and get him to groove them! Or just go for ultimax.
Bushes, tracking, ball joints, track rod ends, wheel bearings. All of these can cause a wheel to wobble. Sure you havent got a sticking caliper and causing one disk to get too hot? Coming to a stand still generally does it as it causes a heat spot.
All of the above have been replaced within the last few months and there is no play within the wheels. Pistons go in fine. But still gonna scrub them down when I next fit new discs.
