History

This is one of only two BT-23G models made, both these West Coast cars exist today. This model is probably the last 'classic shaped' Brabham made, as the revised 'shovel nosed' BT-28 and BT-29 models were introduced around this time. This car hung on the wall at Tom Rust Engineering for ten years prior to its purchase by the current owner. A total restoration was undertaken by T.R.E. preparing the car for serious competition. New suspension and bodywork were obtained from Peter Denty. The original front Magnesium uprights, which are no longer available, were replaced with BT-28/29 units using revised Ackerman plates, to preserve the correct steering geometry. All original parts including spare uprights, not reused in this no expense spared restoration, have been retained for provernance and posterity, and are included in the sale. All restoration records and receipts are also included. The Hewland Mk V gearbox and final drive restored by Taylor Race Engineering and fitted with Mk IX internals and a Quaiffe differential. The original ful length fitted F-2 aluminium fuel tanks have been retained, with the fitment of a custom fuel cell to the rear of the left hand tank. A Lotus twin cam is installed with one hour of track time since a total rebuild by Bob Yarwood. 4:1 exhaust with Super Trapp muffler. Original Brabham spoked magnesium wheels, finished in black chromate, are installed and correct to original specification. 9x13 front and 12x13 rear. Koni double adjustable dampers. Rebuilt original Smiths instruments. All bright work nickel plated. Existing livery is dark green with white number backgrounds. Restored for racing first, show second, the car has normal cosmetic use as a result of a partial season of track time. The current owner is 6'4" and 195 lbs. This is a very quick 'B' car running easy 1.28's at Seattle International and 1.21's 9with chicane) at Portland International, it is also definitely user friendly.
