Street Stage:

E30s respond very well to minor and relatively inexpensive
changes to the suspension.

Sway bars—changing the stock sway bars to larger
diameter bars with urethane bushings produces a car that
corners flatter and feels more stable; you'll wonder why they
didn't come that way from the factory. No loss of ride quality;
fits with AC.
Shocks---installation of Bilstein shocks makes a world of
difference in the way the car handles. Keeping the tires in firm
contact with the pavement is the way to make the car handle
well; Bilstein shocks do this best.

Tires and wheels---modern premium tires on alloy instead
of steel wheels will improve the appearance of the car, but,
more importantly, will also make the car stick to the road like
it never could years ago when it was new. This is both a matter
of performance and safety, wet and dry.

Street and Track Stage:

Sway bars---Bigger sway bars are the mandatory on
serious performance cars.
Modern adjustable bars are sometimes also
available, either conventional bars that mount in the usual
location, or special hollow tubular bars with custom aluminum
mounting brackets.

Shocks---Bilstein Sport shocks are the answer here. Very
firm control, great when driven hard. Often used in
conjunction with fixed negative camber plates at top.

Suspension bushings---should be replaced with
polyurethane bushings at all suspension pivot points, both
front and rear.

Tires and wheels---V- or Z-rated tires on 14", 15", 16",
17", or even 18" wheels

Track and Race Stage:

Sway bars
Modern adjustable bars are also available from
Ireland Engineering, either conventional bars that mount in
the usual location, or special hollow tubular bars with custom
aluminum mounting brackets.

Shocks---Bilstein Sport shocks are the answer here. Very
firm control, great when driven hard. Where rules allow, use
struts modified for coil-over shock type springs, making space
for larger tires and wider wheels. Adjustable camber devices
are necessary at the top of the struts---also available through
Ireland Engineering.

Tires and wheels---V- or Z-rated tires on large diameter
wheels depending on what rules and budget will allow.
