I have a near new BMW OEM Aluminium Strut Brace for sale in Perth. It is in near brand new condition and is for sale as I replaced it with a BMW performance carbon fibre brace. It is extremely easy to install (see attached installation instructions - page 9 onwards) and fits a E87 or E90 model.
They sell for around AUS$300 shipped on eBay from the USA so is real bargain at AUS$220.
Happy to ship anywhere in Australia at buyer's expense - quoted Perth to Sydney 3 to 5 working days $32.
Thank you to overseas members but will not ship overseas due to extremely high freight costs from Australia.
Drop me a note if you would like more details.
Thanks for looking
