Welcome to Classic Retrofit

Classic Retrofit designs and manufactures direct-replacement modern electronic upgrades for classic cars. Our product range includes state-of-the-art electric air conditioning systems for classic Porsche 911s, upgraded CDI ignition units featuring cutting edge modern microprocessor technology guaranteed to produce more torque and total reliability and plug-and-play blade fuse panels with improved power handling and blown fuse LED technology.

Hundreds of delighted enthusiasts now benefit from Classic Retrofit products in vintage automobiles, including Porsche, Ferrari, Jaguar, Alfa Romeo and Mercedes models. Our fuse panels and CDI+ units may be purchased directly from this website, with US customers also served via the famous Pelican Parts webshop, where our products are recommended upgrades.

Classic Retrofit's product range continues to expand, and we have just celebrated our third anniversary in business by releasing an all-new, UK-manufactured upgraded Porsche 911 110A alternator. Our first production run of Electrocooler electric air-conditioning for Porsche 911s sold out in less than 24 hours and we have released a steady stream of software upgrades for the Classic Retrofit CDI+ unit. 

Alongside our product development and manufacture, we are also proud to collaborate with many of the biggest names in bespoke classic vehicles, including the legendary Ruf Automobile GmbH. Classic Retrofit engineering will be incorporated into the latest Ruf CTR: a carbon-bodied supercar costing €550,000. We are exceptionally excited to work with the Ruf team on this truly game-changing project, scratch-built from the ground up.
