Hello we are looking at doing a group buy for Quaife LSD's on here and below are the prices we are proposing numbers dependant. Bit of background we have been selling and fitting these since we have owned the company and have sold 100's of units and fitted ourselves a lot of these, we have never had a failure as yet. This is one of the main reasons we support the Quaife product. Prices are, 02E DSG QDF19R £756 02A QDF8R £538 020 QDF1R 109/111 £538 02Q QDF16R £572 02M 4WD QDF14R £634 02J QDF10R £572 02M 2WD QDF13R £572 ARP BOLT KITS 02Q/02M £103 02A/02J £67 020 £63 These prices are based on 10 orders of any mixed diffs. We can also offer quotes on fitting to just the gearbox or we can remove and refit the box to the car. Any questions let me know.
