Item 2.02.    Results of Operations and Financial Condition.

Cooper-Standard Holdings Inc. is furnishing the following information:

We issued a press release (the ‘‘Press Release’’) on August 14, 2006 that discloses information regarding our results of operations for our fiscal quarter ended June 30, 2006. A copy of the Press Release is being furnished and included herewith as Exhibit 99.1.

The Press Release contains a non-GAAP financial measure (as that term is defined in Item 10(e) of the Commission's Regulation S-K). A statement providing a reconciliation from that non-GAAP financial measure to the most directly comparable financial measure calculated in accordance with generally accepted accounting principles is also included in the Press Release. Managment included the non-GAAP financial measure in the Press Release because it believes such measure provides investors with a better understanding of the measures used by management to evaluate our performance and our compliance with financial covenants related to our indebtedness.

Item 9.01.    Financial Statements and Exhibits.

(c)    Exhibits.

The following exhibit is furnished pursuant to Item 9.01 of Form 8-K:
