1)rear wheels all ways have loads of brake dust on them
is this because iv not adjusted bias valve since lowering?
2) about 7mm on the outer of the rear disc is rusted and isnt clearing, should i replace them or leave them till bearings are shot?theres only 1/2mm of rear pad left also
3)just fitted a new renault dog bone and it looks fine but u can rock the engine still and gearstick moves back and gets caught up in gears due to play/? should i buy hill power uprated one?
4)hill power chip> worth the 150? or not, iv got full magnex de cat and sealed induction kit, this is the next step really?
