When Porsche announced that Rennsport Reunion IV would be held at the famous Mazda Raceway Laguna Seca, we knew that the triannual celebration of the marque wasn't something to be missed. We made sure our calendars were clear for the third weekend in October. Now that Rennsport is less than a month away, we have even more details about what's in store for the event.

The last time Porsche was the featured marque at the Monterey Historics, nearly 150 examples took to the track. We thought that was a lot, but it will be nothing compared to when Porschephiles from around the world descend on Laguna Seca for Rennsport. According to the organizers, no less than 350 Porsches will take part in the on-track racing, and an additional 50 historic models will be on display in the paddock, many shipped over directly from the Porsche museum in Stuttgart. In addition, the newly released 2012 Porsche 911 will be making its first North American appearance.

We'll be in Monterey for Rennsport in just a few weeks to provide you with daily live coverage, but until then you can read more about the Porsches that will be on display after the jump.

More than 350 Porsche race cars have been accepted to participate in the on-track racing during Porsche Rennsport Reunion IV, October 14-16. They will tackle the historic 11-turn Mazda Raceway Laguna Seca, where many of these same cars once turned a wheel in anger during their professional racing day.

Complementing the race cars in the paddock will be a very special display of approximately 50 Porsche race cars that will be showcased to Porsche fans, and each one has its own story. This includes cars from two very significant collections: the Porsche Museum in Stuttgart-Zuffenhausen, Germany, and The Revs Institute for Automotive Research at the Collier Collection in Naples, Florida.

Special cars from Porsche Museum include:

• 1971 Porsche 16-Cylinder, the only one built and intended for the Can-Am series
• 1973 Porsche 911 RSR, winner of the last Targa Florio
• 1977 935/2.0 "Baby," which "added lightness"
• "Moby Dick," the original that many consider to be the ultimate 935 Porsche
• Porsche 961, considered to be the "Uberporsche" race car, and is the one and only
• 911 GT-1 98 LM, which is widely thought to be the ultimate 911
The Revs Institute is an internationally-recognized collection that focuses not only on the automobile as a technological device, but as an agent for social and economic change, and worthy to be considered among the masterpieces of creativity. This 501(c)3 not-for-profit educational foundation is a vast collection in the highly specialized field of automotive historical research, comprising an enormous resource on automotive history for scholars, historians, media, institutions and academia.

Cars from the Revs Institute's exhibit: "Porsche: Designed to Excel" include:
