Hi all, quick question on these enhanced chra replacement centers for td5 turbos. In short are they any good? I've tried to research them online but haven't found any first hand experience. Claimed to spin up faster and be stronger than originals. For only 2 or 3 hundred quid sounds to good to be true but tempting. If any one has any first hand experience, good or bad I'd like to hear about it. Many thanks
