Track 172 Cup
I've developed a noise on the cup which sounds like a flat spot on a tyre (had 2 different sets of wheels and tyres on to check) while turning, it is worse when going round a right hand bend and quite loud, still get it going left but not as bad. Don't get the noise in a straight line or under braking and it doesn't go away mid corner under braking although I haven't been hard on the brakes mid corner for obvious reasons. Mostly get the noise on track and it's just started now at road speeds thought it was a tyre rubbing issue but dont think it is now as there are no marks in tyre or in wheel arch. Top mounts a new PMS ones all tight and can't find anything loose. I've been really busy lately and can't get over to @bloke to have a look at it for me.
