I would agree with the above. I had it on my LS, no problem braking below 40mph but the higher the speed the worse the wobble. It also got worse the longer I left it, to the point that it felt unusable. New front discs and pads, wobble gone. An easy job as well.
Was your local tyre dealer Kwik Fit by any chance!!!
Thank you. No, it wasn't Kwik Fit but I do think these tyre "specialist" repair places are best for tyres and brake pads only. I am guessing you fitted these yourself, any advice on where to buy? Front discs/pads are on offer on Ebay for mid £60 !
