Modified Porsche owners, this is the event for you!

Join us on Sunday, November 17th, 2024, from 10 AM - 2 PM (PT), at Eibach (264 Mariah Circle, Corona, CA 92879) to display your prized modified Porsche at the 4th Annual Porsche Club of America ünStock event.

Join PCA and your fellow enthusiasts for great music, delicious food, and cool modified cars!

Membership in PCA is not required to participate in this celebration of modified Porsche vehicles; however, to have your vehicle considered for display, you must complete the registration of your modified Porsche, with a minimum of 3 visible modifications. Registration is $40 per car.

New for unStock 2024 is our first-ever Exhaust Sounds contest. Here’s your chance to enter your unStock Porsche with a factory or aftermarket exhaust in a contest where it isn’t how loud your Porsche is but how sweet it sounds at idle and high rpm. We’ll have a panel of three judges to determine the best-sounding exhaust. Only Porsches registered for unStock 2024 are allowed to participate. When registering, remember to check off that you want to show off your exhaust. Also, let us know what modifications, if any, you’ve made to the exhaust system.

Please note that your registration must be confirmed to display your car. Registering does not constitute official acceptance. Once your modifications have been reviewed and approved, you will be notified, and a special display hang tag will be mailed to you.

Spectators are welcome to attend – no entrance fee! Again, this year, we will have a Porsche Corral for Porsches that are not part of the show. Limited space is available for the Corral, and it will be on a first-come, first-parked basis.
