             AS REVENUE AND UNIT SHIPMENTS ALSO REACH ALL-TIME HIGHS

               NET INCOME INCREASES 30% TO $0.83 PER DILUTED SHARE
                     REVENUE INCREASES 12% TO $208.0 MILLION
                        UNIT WHEEL SHIPMENTS INCREASE 3%

    VAN NUYS, CALIFORNIA, -- April 11, 2003 -- SUPERIOR INDUSTRIES
INTERNATIONAL, INC. (NYSE:SUP) announced today that net income for the first
three months of 2003 increased 30% to a new record, as revenue and unit wheel
shipments also rose to all-time first quarter highs.

FIRST QUARTER RESULTS

    For the three months ended March 31, 2003, revenue increased 12% to
$207,985,000 from $186,532,000 a year earlier. Unit wheel shipments increased
3%. Net income rose to $22,266,000, or $0.83 per diluted share, from
$17,172,000, or $0.65 per diluted share, for the first quarter of 2002.

    This year's first quarter results included the write-off of non-recurring
start-up costs of $2,500,000 related to the launch of Superior's new aluminum
suspension components business. The company's share of profits from its joint
venture aluminum wheel manufacturing operation in Hungary was $1,948,000.

    At March 31, 2003, Superior had working capital of $272,293,000, including
cash and short-term investments of $155,620,000, and no debt.

EFFICIENCY GAINS

    Chairman and Chief Executive Officer Louis Borick said, "The increase in net
profit margin for the first quarter to 10.7% from 9.2% a year earlier was
primarily the result of efficiency improvements in both of our facilities in
Mexico, especially at our newest plant in Chihuahua that came on-line in late
2001. Our managers and staff deserve a great deal of credit for this
accomplishment. Superior's strong bottom-line results also reflected a favorable
mix of wheel production for this year's first quarter, with more large-diameter
and chrome-plated wheels in the total than last year.

    "We built Superior by consistently meeting our customers' toughest design
and engineering specifications, cost requirements, and delivery schedules. This
well-earned reputation is the reason we are winning major new wheel supply
contracts from current customers and adding important OEM accounts. Our
aggressive expansion plan will allow us to sustain our superior performance at
the far higher production rates that our customers will require in the future."



INVESTING IN GROWTH

    President and COO Steve Borick said, "Our geographic expansion has been
enormously successful - our plants in Mexico and our joint venture facility in
Hungary are among the most advanced in the world. These plants also have served
as test beds of Superior's ability to operate internationally. The experience
has taught us valuable lessons that will be increasingly important as we prepare
for further international expansion in the years ahead.

    "Capacity expansion is only one of the ways we are investing in Superior's
growth. In addition to our Commitment to Excellence and employee training, we
have implemented programs to identify best practices within our organization and
are developing a formal mechanism to ensure that they quickly are adopted
throughout our company. We also are improving our operating controls and
reporting processes, which will be facilitated by the upgrades to our management
information systems and internal computer networks planned for 2003. We are
listening to new ideas coming both from management ranks as well as from our
manufacturing employees - we are open to bottom-up as well as top-down
improvements. These programs will help us maintain the quality Superior is known
for while we achieve savings at every one of our plants and in every aspect of
our business, from the shop floor to engineering to sales to finance."

OUTLOOK

    The COO continued, "Superior delivered an outstanding first quarter,
especially in view of current geopolitical events and continued economic
uncertainty. We continue to gain share of the aluminum wheel market, and based
on new wheel supply programs already announced or in the pipeline, the outlook
for the year's second half is encouraging. However, we are cautious as we look
into the next couple of months, because production cut-backs for certain models
recently announced by some of our OEM customers are likely to affect aluminum
wheel demand in the second quarter."

STOCK REPURCHASE UPDATE

    Superior has repurchased 4,573,000 shares of its common stock since 1995,
including 81,000 shares repurchased during the first quarter of 2003.
Approximately 3,428,000 shares remain to be repurchased under the March 2000
Board of Directors' authorization.
