Technical

Main article: Technical

Like any BMW, the E30 is a complex precision machine, precision-built and designed to last. But even the simplest of machines needs maintenance occasionally, so keep your E30 running the way it should, it helps to familiarise yourself with the design, and the components. The Technical section of the E30 Zone Wiki is your one-stop source for maintenance tips, common problems, upgrades and troubleshooting.


Engines

Main article: Engines

The E30 was available with a range of 4- and 6-cylinder engines to entice both the frugal and the frivolous. The most humble of these was the early 316, which featured a carbureted 4-cylinder M10 engine, while the most powerful standard car was the 325i, with its 6-cylinder M20.

As the E30 developed, more powerful variants evolved. The M10 was eventually replaced by the fuel-injected M40.

Differential

When upgrading your engine, upgrading your differential at the same time is almost mandatory.

Brakes

Main article: Brakes

While moving in the E30 is an utterly delight, the need to stop moving is sometimes necessary. For that reason, the E30 was fitted with front discs on all models. The smaller-powered 316, 316i and 318i saloons were fitted with rear drum brakes, while all six-cylinder models and Tourings had rear discs as standard.

Suspension

Main article: Suspension

All E30s are fitted with McPherson struts for front suspension, bolting up to a single control arm at the bottom. This is reinforced by an anti-roll bar connecting the control arm to the front subframe. The rear wheels have independent suspension of springs and shocks, and are connected to the rear subframe via trailing arms. Another anti-roll bar clamps the trailing arms to the body.
