Brabham

Jochen Mass in his Novamotor powered BT35 at Brands Hatch in October 1971.

After he left Coopers, double World Champion Sir Jack Brabham went into partnership with Ron Tauranac with the idea of producing a range of customer cars in addition to the works F1 and F2 cars. Brabham Racing Developments was formed in 1962 to deal with the customers whilst the Brabham Racing Organisation would look after the works cars. For the next 12 years Brabham's would produce a huge range of incredibly successful cars in many different formulae, F2, F3, Tasman, Sports Cars, FB, all with a reputation for simplicity, ease of use and most importantly competitiveness.
For many years the cars were called Repco Brabhams (as a thank you to Repco for early assistance in providing premises) irrespective of the actual power unit fitted, all cars also bore the BT (Brabham/Tauranac) type number. So successful were the cars that by the early 1970s over 500 cars had passed through the Brabham factory gates. In addition many of the smaller manufacturers around the world frequently "borrowed" the Brabham designs for their own cars e.g. Birel in Italy. This was possibly largely because Brabham preferred the space frame as opposed to monocoque route and it wasn't until the BT 38 in 1972 that production cars employed monocoques. However by the beginning of the '70s Sir Jack had hung up his helmet and sold his share of Brabhams to Tauranac and he in turn sold the company to Bernie Ecclestone, the emphasis soon switched from production cars and the lower formula towards F1 and an important chapter in F3 came to an end.

The first F3 Brabham was the BT9, it was largely derived from the F Junior BT6 and it was very much a Tauranac design with its spaceframe chassis and outboard suspension. The gearbox was a Jack Knight unit based on the Hillman Imp road car, this meant that the rear cross-member was behind the centre-line of the driveshafts. Some F2 BT10s were used in F3, this chassis used a Hewland 'box with Brabham designed side-plates that moved the driveshafts behind the line of the rear cross-member. 13 chassis were built but success was very much limited by the dominance of Jackie Stewart and his Tyrrell Cooper-BMC. A number of drivers converted their F Junior BT6s to F3 spec and had some success.

The BT15 was the car that made the Brabham name in F3. The car was almost identical to the F2 BT16 and once again employed a spaceframe with outboard suspension. 58 cars were built and when powered by the Cosworth engine the car took a hat full of victories.
Some drivers converted the 1964 F2 BT10 to F3 spec probably because the chassis had sheet steel welded to the bottom tubes for added stiffness. Since the cars were under the weight limit this wasn't a handicap. Similarly there were a few conversions of the 1965 BT16 F2 to F3 use, here the most noticeable difference was the use of Lockheed brakes on the F2 car as opposed to the Girlings on the F3 machine.

Natalie Goodwin's BT18 in a F Libre race at Rufforth. Note the revised wider based rear suspension compared to the BT15 above.

The BT18 was designed as a multipurpose chassis for both F2 and F3. Compared with the BT15 the most noticeable change was the wishbone points were set wider apart to give a greater swing arm length to suit the ever widening wheels and tyres. A longer upright was also used to help spread the suspension loads created by wider tyres that caused cracking of the chassis tubes. The new uprights were a development of the F1/Tasman design. The F2 chassis had a few improvements: longer rear uprights, a 2.25 inch longer engine compartment, Armstrong adjustable dampers, fuel relief valve/pressure gauge and light alloy brakes. Since these additions only added £200 to the price many F3 teams opted for the F2 specification. The car once again was very successful with Chris Irwin in the works Chequered Flag car going particularly well. 32 BT18s in F3 spec were built.

The 1967 BT21 (which debuted at the end of 1966) was a further refinement of the previous year's model. The chassis was a little shallower (the top and bottom chassis rails were moved closer together) but importantly it was stiffer and the suspension was slightly modified with a wider track. A new sleeker bodywork was also fitted and the fuel tankage was increased. It all seemed to work especially on rougher tracks were the BT21 was noticeably superior to the BT18. Once again the car was a winner taking numerous victories throughout the year, the only consistently effective rival being the Matra MS5 which dominated in the French Championship. A grand total of 50 BT21s were built.

The BT21X in the nude, the typical Tauranac well-triangulated spaceframe is clearly visible.

The BT21B appeared at the end of 1967 and was almost completely identical to the BT21. The only real changes were the relocation of the rear suspension pick-up points to accommodate even wider tyres and the fitting of a stronger underseat chassis pan. The car still proved hugely popular amongst the private teams and it took quite a few wins but the warning signs were there that minor mods weren't enough as the season was very much dominated by the Tecno.
At the end of the year the BT21X appeared as a mobile test-bed for the 1969 design. Most importantly the (still) spaceframe chassis was derived from the much more rigid F2 BT23 model. The wishbone, damper and rack were mounted in one plane. Suspension modifications and experiments with various wings showed that this would be the way to go for 1969. There were 31 BT21Bs built although some were to American Formula C specification.

Despite all the end of season testing of the BT21X the BT28 was late in arriving and then production problems at the Brabham factory meant deliveries of the car were very late and many orders were cancelled. This was a pity as the car was obviously right, the new rigid chassis made the car much better at putting its power down, especially out of slow corners and the slippery bodywork proved very effective at the quick tracks. All of this allied to the traditional Brabham qualities of good handling, controllability and ease of setting up meant the car was very quick everywhere. There were some early season problems with springs and lifting rear wheels but continued development soon saw these minor complaints dealt with.

The BT28 continued into 1970 with no important changes to the design although as can be seen from the Gerry Birrell picture wing experimentation was still ongoing. A season of sorting meant that it was quick from the start and it won many races during the year, the only real rival being the Lotus 59, especially the works car of Dave Walker. At the end of the year the BT28 had racked up 23 wins from the 60 major races of the year.

Now the front view of the same car.

A typical Tauranac design, space frame chassis, outboard suspension with inboard rear brakes, it proved to be very popular especially outside the UK. However other constructors were learning the Brabham secret and victories were harder to come by although Colin Vandervell in the works car and Jochen Mass managed several. A number of drivers updated their previous year's BT28, a relatively simple conversion. The BT35 designation also applied to formula B and Atlantic cars.

Designed by Geoff Ferris after the Ecclestone takeover, the first monocoque production Brabham had a square section aluminium tub with a steel subframe behind the cockpit for the engine/suspension. Unequal length wishbones were fitted to the front with lower wishbones, a single top link and twin radius rods at the rear. Coil springs and dampers were outboard but the rear brakes were inboard. Late delivery followed by little development and a disinterested factory meant the only winner during the season was Tony Brise who won 3 races in the semi-works chassis. Once again the BT38 designation covered F2, FB and Atlantic as well as F3, the Formula 3 variant being sometimes known as the BT38C.

This was to be Brabhams final year in F3 and the BT41 would prove to be somewhat of a disappointment. Consisting of an angular aluminium monocoque, with an 18 gauge mild steel inner skin treated with an anti-corrosion plastic to bring it up to the minimum weight limit, it used conventional wishbone suspension with outboard coil springs and dampers. It was the first production car to feature what would become the standard F3 gearbox, the Hewland Mk9. The general layout was very similar to a tidier lower version of the BT38. Only a few cars were sold in the UK although it proved more popular and successful in Italy. Towards the end of the year Larry Perkins in the works example showed what might have been in a well sorted example. A number of cars were converted to the new 2-litre formula, particularly in Italy, were they ran competitively for several seasons.
