AQM/SQS Porsche Sequential Shifter Conversion Kits

Product Background

This sequential shifter kit was originally developed by Cartronic Motorsport in Germany for Porsche to offer as an option for Turbo and GT models equipped with manual transmissions. Although Porsche AG funded the development of this sequential shifter unit, due to their upcoming PDK transmission they ultimately chose not to make this a factory option. After successful development by Cartronic Motorsports and their manufacturing partner SQS, they decided to offer the product independently through distributors and hundreds have been delivered to Porsche customers throughout the world. For the last several years we have been the exclusive distributor for North America and Canada, and during that time we have sold dozens to satisfied customers in the region. We have also successfully campaigned one of these shifters in the AutoQuest Rally GT3 RS, competing in several multi-day events both in the US and Europe. 
How It Works
The concept was to develop a method of converting a traditional H-pattern shifter to a sequential, thus creating a race car driving experience in a Porsche street car using a conventional manual gearbox. Below are diagrams of how the main sequential conversion units function for both the 911 and  Boxster/Cayman.
