Just days after the track hosted the opening round of the 2018 Blancpain GT Series Endurance Cup Monza is again in use as Porsche conduct testing for a range of interesting machines.

Amongst them, seen clearly in these images captured for DSC by Fausto Mattei, is what is believed to be the soon to be unveiled 2019 Porsche 911 GT3-R. The car, complete with rather more extreme rear and side aero than seen on the current version of the car.

Seen side by side the differences between the current (in all over carbon) and potential newer version are more obvious. The front splitter and dive plane section has changed, and the rear diffuser is larger, more prominently though there are new and large air intakes/ cooling ducts behind the doors, improved cooling for a more powerful engine?

Very likely, but our man trackside did offer an opinion (from the sound that he was hearing) that the car might just be turbocharged! That would hardly be a stretch in the current company in GT3 but it would be a first for Porsche’s GT3 offerings.

Also on track has been a race-prepped version of the Cayman which may well be the much-trailed replacement for the now rather out-gunned Cayman GT4 Clubsport MR, Porsche’s current GT4 offering barely a year old but already seeing customers moving over to the new and (in un-BOP-ed form) more powerful alternatives.

The car here has what appears to be a deeper rear wing but with very limited further visual changes, the likelihood then is that any 2019 version will be aimed at a power hike, or an engine upgrade from the current 3.8 litre six cylinder unit.

Both cars are expected to be offered for customer sales for the 2019 season which means that we are almost certain to see both the 911 GT3-R and Cayman out and racing, most likely in the SP-X class of the VLN, in exactly the same way as their forebears!
