Hey all,

So as some of you may have seen we have been busy developing a range of products for the 991 GT range and have already released a few to market. The initial take up and feedback has been fantastic so we're really excited to share our future products with you all soon.

Our previous 991.1 GT3 RS and subsequent 991.2 GT3 were used for the development of the parts so far but now we have returned back to the 991.1 GT3 RS and this will serve as the test bed for all of development moving forward..

JCR Miami Blue 991.2 GT3

This thread will serve as a a blog of our own 991.1 GT3 RS as we conceptualise, test and develop future parts and packages. We will also share all new product development teasers prior to release and any other interesting goings on.

Theres a little catching up to do here but this first post will take us to present and then moving forward ill be sure to keep this thread updated often with cool content!

So, the car! A 991.1 GT3 RS with all of the right options, a perfect base to work from..

First thing was to add our Bolt-On Titanium Tips to the otherwise totally OEM exhaust system.

The factory tips feature an internal step down which does kill some exhaust note & volume from the factory set up. Changing out to our titanium tips on an otherwise stock system has a subtle yet noticeable effect on the sound, as you can hear below in the short video..

Next up, JCR Titanium Silenced Centre Bypass install..


JCR Titanium Silenced Centre Bypass

The reason I selected to install the silenced version of our centre bypass is that we will install next the JCR Titanium Valved Side Silencer Bypass parts. Together with the silenced version of our centre bypass this means that you retain valve functionality and the exhaust volume will be reduced to a very manageable level for every day driving.

First the factory titanium centre section was removed. Notice the JCR Titanium Bolt On Tips installed at this stage.


OEM Titanium Centre Silencer with JCR Titanium Bolt On Tips

A comparison of the factory titanium centre section together with our own. I can never quite understand removing a titanium piece to then install a lesser grade material. Huge weight loss and great sound.

We then built up the two components being installed. You'll notice here that the tips having already been installed have already begun to heat cycle and colour shift, at this stage they have not had any real heat put through them so are firmly in the 'gold' stage.

Assembly is then installed to the car..

And tips removed just to take a look at our flange detailing, replicating the OEM silencer flange detail is important.

Videos coming this weekend of the car with the new exhaust components installed.

Prep is currently under way for a track event at Silverstone GP circuit on Monday (12th) so we're applying our preferred set up and a few small tricks ready for the day. All will be shared in the next post.

Hey all,

Just a quick update with the build.

A good shakedown test at Silverstone GP circuit to test our new Titanium Shim Packs and setup. Unfortunately only one dry session cut our test time down a little however we'll be back soon after some more adjustments to fine tune the car.



Those with eagle eyes might well spot a few details on the car of interest in the image above. More details coming soon there!

In the mean time..

The car was specced and delivered with silver belts and door straps, decided to swap them out with OEM Yellow 3-point belts and OEM GT4 Yellow door pulls, perfect fit and sets off the interior nicely!




A perfect match with a set of our very own JCR Billet Aluminium Lightweight Shift Paddles finished in Racing Yellow




Performed brilliantly on track, a really great addition and the extra paddle length is very welcomed on track!



Our direct fit shift paddles are available in a range of finishes and are available to order below!

Oh, and the JCR Titanium Bolt-On Tips are colouring up nicely after a few hot laps!

Look forward to sharing more updates soon..

Thanks for the compliments!

Our Titanium Side Silencer Bypass (with and without valves) will be available very soon, look forward to sharing details and images of that. A few small details really will set this apart from others.

Cannot wait!

This is the perfect system (for me) and the main reason I have not ordered Akrapovic or something similar.

I want the ability to quiet it down yet in my neighborhood, or when my wife is irritated of the noise...lol.

Hey all,

Another update on the build, this time bringing us up to the latest state.

As mentioned above we prepared the car for its first on track run utilising our prototype Titanium Shims and the results were very encouraging. We plan to do a sweep of settings to properly baseline and then we will start to test more of our chassis modifications which will be coming soon.

As usual, the car was delivered from the factory with a very safe set up, we changed this drastically and a back to back test vs another 991.1 GT3 RS saw a difference of 2.2 seconds in lap time, the cars are otherwise identical so it just goes to show how much time there is in a properly set up car!

First up was to remove the factor wheel arch grilles, a very small increase in front downforce plus more clearance for the new ride heights



Doesn't look too bad either..



We then went on to add our Titanium Shims plus set up the car to our preferred settings and corner weight



We then went on to apply some new OEM parts, 991.2 GT3 RS side air intakes plus OEM 991.2 GT2 RS side skirts. Both quick and easy direct swaps for the OEM parts.

First up the OEM 991.2 GT3 RS side air intake vents..



As you can see below, visually a very big difference to the OEM 991.1 GT3 RS side air intake vents



Install was straight forward, remove the standard vents



Clean the area



Install the new 991.2 GT3 RS side air intake vents



Remove the pre installed backing to the 3M VHB tape and admire the change in appearance

Then it was time for the OEM 991.2 GT2 RS side skirts. A big visual difference here to the standard 991.1 GT3 RS parts..



One step closer to a GT2 RS!



Install very simple, remove all of the clips and bolts. Pull gently and the skirts are removed, reverse to install the new parts. The difference is very noticeable!



For anyone who is interested, I can get more 991.2 GT2 RS side skirts at very reasonable costs, if you're interested please feel free to send a PM for pricing.

I have some more interesting developments coming soon, look forward to sharing then!

The said the same to me too, same for the skirts.

For the end plates, we're producing a Carbon fibre version which is profiled more aggressively. Hope to release more info soon on this.
