991 GT3/ RS/GT2 RS Upgrades
Since its introduction, the Porsche 991 GT3 has earned a reputation as one of the finest driver’s cars of the modern era. Equally rewarding on circuit as it is on the open road, the 991 blends exceptional performance, precise handling and surprising everyday usability into a package that appeals to both dedicated track enthusiasts and road drivers. Whether it’s carving through your favourite B-road, covering hundreds of motorway miles or tackling a track day, the GT3 is at home in every environment. The more focused GT3 RS builds on this foundation with additional aerodynamic development, chassis revisions and an even greater emphasis on outright performance.
For owners looking to take their 991 GT3 or GT3 RS to the next level, there are countless upgrade options available. Having worked extensively with these cars, we can advise, supply and install modifications that suit your driving goals, whether you’re chasing faster lap times, improved road manners or simply a more engaging driving experience. To help you decide, we’ve highlighted some of the most popular upgrades below, together with pricing and a brief overview of the benefits each one delivers.

ENHANCED Exhaust SYSTEMS
In 2019 the new European legislation came in that meant nearly all sports had to carry OPF (otto particulate filters) to ensure their emissions are low. Because of this, the exhausts in these cars are quieter than most people imagine.
Luckily we have a plethora of exhaust upgrades including offerings from JCR, Akrapovic, Milltek to name a few. Both race pipes and full exhaust systems are available.
JCR From £4395 / Milltek From £2495 / Akrapovic From £3590 +VAT

MICHELIN PERFORMANCE Tyres
As a Michelin Performance Partner, there is a tyre for every occasion. Many clients who enjoy their 991 on trackdays are amazed by the feedback provided by the Michelin Cup 2 and also to their surprise the durability of the tyre.
For those wanting to extract the ultimate lap time, the Cup 2 R gives an almost racing slick level of grip whilst still being able to use on the road.
Another tyre from Michelin that is very popular is the Michelin Pilot Sport 4S, which can be used occasionally on track but has been designed to give all year round performance and as such is a great option for those who use their 991 for touring and road trips.
The newest of the bunch is the Pilot Sport S 5 which offers unbeatable wet weather performance on both road and track, whilst staying mostly uncompromised in the dry.

Performance Brakes
Porsche offered two brake options for the 991 GT models. An incredibly well sorted steel (actually all car brakes are cast iron to be specific) or a lightweight carbon ceramic brake disc (PCCBs.) For those with steel brakes on their 991 we can offer a range of pad upgrades for better feel and ultimate stopping power (factory fitted pads are now softer than before due to new environmental regulations), along with Manthey braided brake lines for a more consistent pedal-feel under heavy use. We can also offer upgraded performance brake fluid that has a higher boiling point, so is more stable when used heavily on circuit.
We also offer a selection of upgraded brake discs for your GT Porsche, both steel and carbon ceramic options are available. For those looking for a cup car-esque brake feel, PFC steel discs are a worthwhile upgrade as they offer significantly improved braking performance alongside reduced weight due to its innovative ‘two-piece floating’ design.
Braided Brake Lines and Performance Fluid Prices from £499 +VAT

Geometry and suspension
All Porsches leave the factory ready to go fast, however the factory setup builds in a degree of safety so that the car will understeer at the limit which most drivers find easier to manage. If you are looking to unlock some more performance from your 991 GT3, we can adjust their factory fitted hardware to be even more driver focused. If you are running with the Cup 2 R tyre, a popular option is to also remove the factory suspension and fit Manthey-Racing fully adjustable coilovers. This gives the chassis a stiffer platform to work from and in turn take advantage of the extra grip these tyres can provide you.
Geo Prices from £630 + VAT
Suspension Upgrade Prices from £12,500 + VAT

Full Manthey Racing conversion
Manthey Racing upgrades allow your 991 to be driven at the extreme with even greater precision and predictability, whilst not harming your Porsche factory warranty and in turn its resale value. Win all around really.
GT3 Price from £36,960 +VAT
GT3 RS Prices from £54,391 +VAT
GT2 RS Prices from £83,304 +VAT

Seat adjusters
The 918 bucket seats in your 991 (ignore this if you have Sports seats!) are one of the best designed seats ever built in our opinion, hence why they have been fitted to Porsches for a decade. The seats adjust forwards and backwards, and rarely for a full carbon bucket seat they allow height adjustment. The only degree of adjustability they won’t allow is the angle of the seat to be tilted, we have a solution that we have fitted to loads of clients cars, as well as our own. The seat adjusters also allow taller drivers to get in the car with a helmet on, and have plenty of headroom.
Fitted Prices from £325 (Per Seat)
