Hi guys got brakes binding and Knocking from the back end. Took it to a garage and they said I need new calipers which gaz Watson is sorting for me but also said my suspension is what's Knocking. Upon looking under neath they said I need new rear sub frame trailing arms x6 bushes and drop links. He has all the parts from donor cars. He had suspension from version 5/6 to go on a new painted sub frame with bushes all for £270 I have to purchase some drop links and calipers myself on top of that. It's all for my newly acquired rb5 no 321. TIA
