We're super excited to have picked up our latest JCR project car, sitting along side our 991 GT2RS MR, Cayenne Turbo S E-Hybrid (with many others on the way)
The JCR 718 GT4 v2.0 is a PDK 718 GT4 finished in Arctic Grey with every option you could wish for..
Many of you will remember the original JCR 718 GT4 - We accomplished some great things with that car and demonstrated that our product line does exactly what it says on the tin and still holds the record for the fastest 100-200kph time recorded for a 718 GT4 / Spyder
Since the first JCR 718 GT4 left us over 18 months ago we've been working on some great new ideas and having another 718 GT4 in our fleet will allow us to complete development and deliver a bunch of new and exiting products for this fantastic platform.
Every Sunday for the next 8 weeks we will be sharing the build progress on our blog and social media channels until we launch the car at our first Track event on 18th March - This thread will then serve as a place for all of our developments to be discussed along with testing results from each of our track events throughout the 2023 season
We can't wait for what 2023 has in store!

This week we're bringing you our fifth instalment of project JCR 718 GT4 v2.0 where we will be focussing on converting the car to accept centre lock magnesium wheels and changing up the brake set up to Surface Transforms PCCB replacement discs.
Centre lock wheels on Porsche models are a little 'love it' or 'hate it' but we're certainly in the camp which find them to be more of an advantage than an annoyance. In part, due to the fact that we use the Hytorc Centre Lock Wheel Gun with such great success.
The conversion is relatively simple once you understand which parts are required, we will likely offer a kit of parts on our website including some JCR items to ensure a simple direct replacement kit for any owners who wish to go down the same path.
We opted to fully replace the bearing assembly which will allow quick and easy return to standard once it's time for the car to move on
In Episode 02 we installed the Manthey Racing PCCB pads, lines and Castrol SRF fluid and also mentioned that we will be offering some further upgrades for the factory PCCB disc in the future.
We've ran Surface Transforms discs and Pagid RSC1 pads on all our track builds, including JCR 718 GT4 v1.0 and have a great understanding of their advantages. Gathering data on this car is important and will serve as a great benchmark for performance whilst developing products to further optimise the factory PCCB set up.
We dusted off a set of ST discs we had in stock from a previous build and installed them to the car. This also helped us further understand any potential issues with fitment across the cars, especially 718 with centre locks installed.
Brake pad spec with the ST's will be no different than usual, Pagid RSC1 provide a safe, reliable and quiet road driving experience with fade free track driving. The perfect balance for owners who use their cars to drive to the track as well as lap all day!
We will be switching between various brake set ups throughout the year and will be sure to share any interesting findings!
One of the main reasons for going with the centre lock conversion on our car is to enable us to run the factory 718 GT4 RS magnesium wheels which offer a significant weight saving over even the lightest of aftermarket 5-lug options. Shockingly at a reasonably comparative cost too, once all things are considered.
For the finishing touch we opted for silver Porsche crests for the centre lock cap however we will offering our own design in the coming months.
We purchased two sets of wheels, one which we will run as our 'Dry' set and another for any wet weather running. For the dry set we will be running Michelin Pilot Sport Cup2R's. Undoubtedly the finest road legal track tyre there is.
For wet conditions and any long distance driving we will run our 'wet' wheels installed with Michelin Pilot Sport 4s tyres. Again, in our experience the highest performing tyre for cooler wet conditions.
We will be experimenting with wheels and tyres, mostly on the front axle throughout the 2023 season in order to unlock some extra speed from the car. As anyone with experience knows, the limiting factor for performance on this platform is the front end and how it works in conjunction with the McPherson rear, we have a few tricks up our sleeve to take care of this. (no, it's not an unwieldy understeer inducing rear wing)
As a small bonus we also treated the car to a set of direct replacement BMC air filters - Every little helps in this game.
Watch this space on the intake side of things, we're currently working on a design concept which could yield some interesting results... and feedback!
We're getting towards the end of our initial modifications to the JCR 718 GT4 v2.0 with only a few weeks remaining ahead of the final reveal where we will be taking the car out on track (March 18th) for its first track event of 2023.
I think we can all agree that the car is really starting to take shape, watch this space for more updates over the next couple of weeks
V2.0 huh, look forward to seeing and hearing what you come up with the GT4 and Spyder this time around.
Still very much enjoying my JCR Silenced Valved Race Pipe!
Great to hear! No changes to our current products, just additional parts that will becoming available once we get the final testing and validation complete. We absolutely love this platform

this is great news. Looking forward to seeing some new products!
We're excited to bring you the first instalment of the JCR 718 GT4 v2.0 project. Over the next 8 weeks we will be sharing an update every Sunday until we reveal the car in it's 'completed' state.
This week covers the interior enhancements we've made to the car so far. Many of you will remember the original JCR 718 GT4 (finished in Crayon / Chalk) and this new 718 GT4 PDK will be the testbed for a number of new parts and developments throughout the 2023 season.
Changing out the factory shift paddles was essential. The factory paddles create a numb shift feel and also their size can be an issue when driving the car on track and shifting gears on corner entry / exit.
We optimised all aspects of the factory shift paddles. Increased reach, added details on the rear to improve grip, added length and most importantly a much more positive feel when requesting the shift
This change is purely an aesthetic touch but there’s no doubt that the JCR seat covers add some much needed character to the interior of this particular car and also pays homage to some of the more classic models, especially in this particular cloth.
OEM SCHROTH SAFETY HARNESSES
We also took the time to install the factory Schroth harnesses to the driver and passenger side of the car. Quite an involved job on the 718 platform but well worth the effort as this car will be used to its fullest potential from the first time it’s driven on track!
With the relatively easy job of the interior upgrades now completed we can put our efforts into some of the more technical elements of the build. Look out for the next instalment of our JCR 718 GT4 v2.0 project coming next Sunday (Sunday 5th February 2023).
