                   PENSKE MOTORSPORTS, INC. AND SUBSIDIARIES
                       UNAUDITED PRO FORMA FINANCIAL DATA
 
     The following unaudited pro forma financial data ("the Unaudited Pro Forma
Financial Data") as of June 30, 1997, for the six months ended June 30, 1997 and
for the year ended December 31, 1996 have been derived by the application of pro
forma adjustments to the financial statements of PMI incorporated by reference
in this Prospectus and the applicable financial statements of NCMS. The
unaudited consolidated financial statements of PMI include NCMS as of June 30,
1997 and for the period from June 1, 1997 (the effective date of approximately
69.9% control of NCMS) to June 30, 1997. The pro forma statements of income for
the year ended December 31, 1996 and for the six months ended June 30, 1997
account for NCMS as if it was a wholly-owned subsidiary as of January 1, 1996
and January 1, 1997, respectively. The pro forma balance sheet gives effect to
the acquisition of the minority interest of NCMS as if such acquisition had
occurred on June 30, 1997. The adjustments are described in the accompanying
notes. The pro forma financial data assumes that the minority shares of NCMS are
acquired using PMI common shares. See Notes C and E of the Notes to Pro Forma
Financial Statements for the impact on pro forma net income and pro forma net
income per share assuming that 50% and 100% of the NCMS shareholders elect to
receive cash. The Unaudited Pro Forma Financial Data do not purport to represent
what the Company's results of operations actually would have been if the
acquisition had been consummated on the date or for the periods indicated, or
what such results will be for any future date or for any future period. The
Unaudited Pro Forma Financial Data should be read in conjunction with 1) the
"PMI Selected Financial Data", "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and the financial statements set
forth in PMI's Annual Report on Form 10-K for the year ended December 31, 1996
and Quarterly Report on Form 10-Q for the quarter ended June 30, 1997 which are
incorporated herein by reference and 2) "NCMS Selected Financial Data",
"Management's Discussion and Analysis of Financial Condition and Results of
Operations of NCMS" and the financial statements included elsewhere in this
Prospectus.

               NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS
 
JUNE 30, 1997 PRO FORMA INCOME STATEMENT
 
     A. To record: 1) amortization expense of $243,000, using an amortization
period of 40 years, for the period from January 1 to May 31 on $23.3 million,
which represents the excess purchase price of the majority interest in NCMS over
the fair value of the net assets acquired; 2) amortization expense of $143,000,
using an amortization period of 40 years, for the period from January 1 to June
30, 1997 on $11.4 million, which represents the excess purchase price of the
minority interest over the fair value of the net assets acquired; and 3)
additional depreciation expense of $100,000 on the increased valuation of the
NCMS fixed assets as a result of purchase accounting adjustments.
 
     B. To reverse the minority interest expense recorded in the PMI
consolidated statement of income for the six months ended June 30, 1997,
reflecting the ownership by PMI of all of the NCMS Stock.
 
     C. The unaudited pro forma statement of income reflects the acquisition of
the minority interest of NCMS assuming that all NCMS shareholders elect to
receive PMI common shares. If 50% of the NCMS shareholders elect to receive
cash, net income would be reduced by $133,000 and there would be no impact on
net income per share for the six months ended June 30, 1997. If 100% of the NCMS
shareholders elect to receive cash, net income would decrease by $266,000 and
there would be no impact on net income per share for the six months ended June
30, 1997. The reduction in net income reflects additional interest expense, net
of tax, on the cash payment to the NCMS shareholders.
 
DECEMBER 31, 1996 PRO FORMA INCOME STATEMENT
 
     D. To record: 1) amortization expense of $868,000, using an amortization
period of 40 years, for the year ended December 31, 1996 on $34.7 million, which
represents the excess purchase price over the fair value of the net assets
acquired; and 2) additional depreciation expense of $200,000 on the increased
valuation of the NCMS fixed assets as a result of purchase accounting
adjustments.
 
     E. The unaudited pro forma statement of income reflects the acquisition of
the minority interest of NCMS assuming that all NCMS shareholders elect to
receive PMI common shares. If 50% of the NCMS shareholders elect to receive
cash, net income would be reduced by $266,000 and there would be no impact on
net income per share for the year ended December 31, 1996. If 100% of the NCMS
shareholders elect to receive cash, net income would decrease by $532,000 and
net income per share would decrease by $.01 for the year ended December 31,
1996. The reduction in net income reflects additional interest expense, net of
tax, on the cash payment to the NCMS shareholders.
