<dl><dt>Body</dt></dl> The E30 M3 differed from the rest of the
E30 line-up in many ways. The M3 was equipped with a revised stiffer and more aerodynamic body shell as well as "box flared" wheel-arches to accommodate a wider track with wider and taller wheels and tires. The only exterior body panels the standard model 3-series and the M3 shared were the hood, roof panel, and sunroof.
<dl><dt>Suspension</dt></dl> The E30 M3 differs from the standard E30 by having a 5x120 wheel bolt patern. The E30 M3 had increased
caster angle through major front suspension changes. The M3 had specific solid rubber offset control arm bushings. It used aluminum control arms and the front strut tubes where changed to a design similar (bolt on kingpins and swaybar mounted to strut tube) to the
E28 5-series. This included carrying over the 5 series front wheel bearings and brake caliper bolt spacing. The rear suspension is a carry over from the
E30.
<dl><dt>Brakes</dt></dl> The E30 M3 had special front and rear brake calipers and rotors. It also has a special brake master cylinder.
<dl><dt>Driveline</dt></dl> The E30 M3 had a Getrag 265/5 5 speed gearbox, and rear differential with 4.10:1 final-drive ratio and 25% lockup.
