Units 3 & 4, 256-258 Musgrave Rd, Coopers Plains QLD 4108

The workshop is co-located with Rencal Motors. There is no manned retail store front for walk-in Diff Lab enquiries. Please call or email instead. Visits to the workshop are strictly by appointment only, and those appointments rarely occur. Please do not show up at the workshop unannounced, as you will be disappointed. All differentials must be couriered to the shop. Only regular trade customers may make deliveries, and never private customers. Do not call the Rencal Motors phone number for Diff Lab enquiries. If you bother the Rencal Motors workshop with Diff Lab enquiries, your job will not be completed. If it is in pieces, it will be returned to you as-is, sent via a cash on delivery service. Do not bother Rencal Motors with Diff Lab enquiries.

Important:  Differentials must be thoroughly drained and cleaned prior to delivery. You must not send differentials containing oil via courier. Uneconomical charges apply for cleaning and draining differentials. Do not turn up at the workshop. Substantial charges apply for call-outs to the shop for surprise visits. I operate from multiple premises and other independent BMW workshops where I am needed. Surprise visits cannot occur, and you will be billed at the time of your invoice for the inconvenience caused to me and the Rencal Motors staff. -Mike

Price enquiries

If you want Diff Lab to beat a price on a stocked item found elsewhere, use this form to send a link to the competitor's price. Customs duty, taxes and freight are taken into consideration for international orders. Remember that the reputable USA retailers will not supply you with a fake invoice for import tax avoidance. If ordering from outside Australia, Diff Lab does not provide fake customs documents.
