that left a lot of cabin and boot space for the car's overall size. The semi-trailing arms have been criticized for the dynamic toe and camber changes inherent to the suspension geometry, causing bump steer in hard cornering situations (such as racing and autocross). Nonetheless, reviewers praised the handling of the E30. A widened version of the E30 front suspension and the drivetrain from the E30 325i were used in the BMW Z1 roadster. The BMW Z3 and BMW Compact (E36/5) rear suspensions are also very similar to the E30, but utilizing five-lug hubs. The Z3-based BMW M Coupé uses a widened version of the same rear semi-trailing arm suspension along with stronger hubs. Brakes For the front wheels, all models use disc brakes. Early 316/318 models have solid discs, while all subsequent models have vented discs. For the rear wheels, most models use solid disc brakes, except for some early models: 4cylinder & 6cylinder models which use drum brakes. Anti-lock braking system (ABS) became available in 1986. Model range United States & Canada The model range in the United States consisted of the following: 318i (1984-1985 using the M10 engine, then 1991 using the M42 engine) 318is (1991 only) 325, 325e and 325es 325i, 325is (1987-1991 only) 325ix (1988-1991 only) The primary distinctive feature of the BMW E30 models produced for the North American market in 1984–1987 is the protruding front and rear aluminum bumpers. These bumpers are commonly known as "diving boards." In 1987, the anodized aluminum bumpers for the North American market were shortened by revising the cover/fillers and shortening the shock absorbers on which they were mounted. In mid-1988 (for model year 1989), shorter body-coloured plastic bumpers replaced the aluminium ones altogether. South Africa In South Africa, only the two-door and four-door sedans were built, four cylinder gasoline (petrol) models production continued there until 1992. Despite the introduction of the M40 engine, the old M10-powered 316 continued to be sold in South Africa until 1991, gaining the new bumpers when the range was updated. The 333i is a South Africa-only model, and the South African 325iS models were a different specification from 325iS models sold in other countries. M3 model The BMW M3 utilised a widened and heavily redesigned variation of the two-door body style, therefore the M3 shares few body parts with other E30 models. The M3 suspension is also significantly different from regular E30
