TIA. Have fun with the new toy.
Brakes - you can do either the Brembo upgrade or the Stoptech upgrade. You can then select any pad, this was one of the key reasons we moved away from the std PCCB, as there are no other pad options....therefore limiting the dialing in or adaptation of the pads to the drivers requirements or track requirements.

Pads - we have tried both the Pagids and the PFCs on the 996 and 997 (both GT3 and TT), and have been most happy w the balance, feel, pedal modulation and bite w the PFC set up, and that is what we are going to try for our test day next weekend (Thunderhill, Nov 14th....assuming we have dry weather)

We will post some other pics of the other upgrades being done to the car in preparation for our test day.....lots more GOODIES to come for this project.

GT3 2010 suspension - next steps

As we have said....we're moving fast on this project, no small steps being taken, but big steps, and very deliberate steps...each piece, each element is being reviewed and selected to achieve optimum results.
So, as we knew from the testing we have done w our customers 996 GT3, 997 GT3, 996 TT and 997 TT, the suspension has too much play and movement when you bring the car to the track....in fact, it can be a near frightening experience when you really get on the brakes hard, like going into braking for Turn 2 at Laguna, and you can feel the car wiggle from side to side....and you're just holding your breadth hoping that the car will stay going in the right direction....but...
So, when we have installed replacement bushings, links, toe links....the car has settled right down, and become much more stable, but also much more refined in responding to inputs, not just under braking, but all thru the turns.
So, the 2010 GT3 needs this same level of refinement, so, off w the OEM, and on w the new, and only the best will do for sure....
(You can also see the new Ferrari 599 we're installing a Novitec suspension on this week)

Here are more pics of the front side....sways, thrust arm bushings, toe links...time to get rid of all the flex, and add some suspension tuning as well. We're not finished w the suspension yet w these pieces, but this will give us a good baseline to compare the current 997.2 GT3 against what've we known and had for the 997.1 GT3 in terms of setup...then we'll push the envelope a little farther.
You can also see the new Stoptech brakes as part of the package we have been working on.
There is a pic of the various toe links, so you can see the difference in the front vs the rear set, both in terms of design as well as strength and length.
Stay tuned.....more to come, and we'll detail the FULL roll bar, shock tower brace, and harness bar install. We've had direct experience w one of our customers having an unfortuneate experience at Turn 9 at Thunderhill and rolling his GT3 multiple times, yet walked right away, as we had the full roll bar, shock tower and harness bar installed, and saved his life (GMG system was installed in that car, and GMG solution going in our car as well...you can never be too safe, but we also want structural strength and integrity, as we need a solid platform to tune the suspension from)

Thanks for clearing that up Fabryce. I'm interested to see where this car goes in terms of modifications.

Just wanted to say thanks to those that stopped by today to look at the car and the progress that we are making on it. Those that came got to get a glimpse of what we have yet to report here but will post soon.
I should have new videos and pics of the latest development once we are sure that the car is moving along nicely.

Thanks again

Robb

I believe i was the first to see the car today and she is an absolute beast. The exhuast note on this car is amazing. Im excited to see what else these guys have in store for this car. Best of luck next week at Thunderhill. Thanks again Robb

And....the build continues.
As was recently stated in another post....safety is REALLY important, and we know that the GMG roll bar has the build quality and strength...so, in goes the new GMG designed roll bar / harness bar / rear shock tower brace for the 2010 GT3 (which you can get from us, and also the installation if needed). The new design has a different fastener approach, even furthering the strength and rigidity of the solution. We are also installing Willans harness sets for both seats (we have the new Porsche CF seats on both sides).
Since we're going to the track this next week, this is a necessary step in the build process....

Any reason why you decided to stick with the OEM drop links?

Good eyes....nope...those will be going too. Just like in our race cars, we will be going thru and removing the flex elements, or where there is both a flex or strength issue. We believe the stock drop links need to be replaced for both reasons....we have seen some snap in other cars where the added stress from the upgraded bar stiffness and the energy from track use, and we want tight connection.
We don't think any one could feel the difference in the flex between stock and aftermarket sway bar end links, but we want this to be stout.

We won't have the new suspension in before our test day this coming Saturday (and weather is now looking good...near perfect, cool and dry). The new suspension is just being created now (NO one has the new suspension yet, not on any car, much less one for the new 2010 GT3....but, we have a LOT of experience w this suspension, and we flat out want to have all the tricks we need to make an awesome car). Look for the new suspension to go in the car in December, and it will NOT cost a fortune, we're not putting Penske's in there (although that would sure be sweet))

We designed our sway bar kits to be direct bolt on replacement bars for Porsche cars and to work with the existing sway bar end links. In the past and as it (currently) with some other lesser quality sway bars you are forced to use a rod end style drop link.
While this works OK for a race car where noise is not much of a concern it is an issue for Porsche owners who drive there cars on the street and don't want to deal with the maintenance and noise made by these types of drop links.

For example the 996TT and 997TT was a problem for anyone who wanted to upgrade sway bars- You had to purchase curved aftermarket drop links because of the axle issue. Working with Eibach we were able design and build a sway bar that worked with the stock drop links eliminating this problem.


To make a long story short you have the option to leave existing sway bar end links if you want the benefit of our World Challenge sway bar or you can upgrade to a rod end style link if you want to get every ounce of performance from your suspension.


We feel that working with Eibach on the design and utilizing there state of the art manufacturing as well as highest quality steel available our the GMG World Challenge sway bars are the best around. These bars are built to our specification by Eibach and are not standard production bars that have been coated another color and relabeled like some other companies sell.


All sway bars are not the same.. There are only 2-3 companies world wide than can properly bend complex sway bar designs that come on Porsche cars.

Yeah, what he said!
To answer why we chose to not upgrade those links yet it is because we are wanting to build a project car that most other members on here or other owners of the 997.2 platform can take advantage of as well. We are not here to build a project that others cannot do, that serves no purpose to us or anyone else on here as it just turns into a "dream project". Everything you see on the car we provide and had a hand in the development process. We have gone to great lengths to ensure that the best have been chosen and partnered with during this project.
Look forward to more questions and happy to help those that are interested.
Thanks

Robb

What...you didn't think we were done already did you?
We busy...busy....busy....
And, we're blessed w business booming for us, so hard to find the time in the shop to do the extra mods and tweaks that we want complete before the track time this weekend.
So...we have two more major steps planned before the weekend, and here is the next one. You heard one of the guests who stopped by the shop to see the progress on the car talk about the nice sound.....and as someone said today, this sound is a "Man" sound....there is nothing secret about its intentions. But, the fun is that you can sit and play w the valving and change the sound note from aggressive (loud, but not out of control), to MEAN (we wanted it to sound just like a Cup car at the track....we LOVE the sound of the Cup car...and we think we have it, but Saturday will be the true test).
Here are some pics of the 2010 997.2 GT3 headers, cats and exhaust.

So, pay attention to the OEM bends, from the output pipes of the exhaust manifold to the cat....a pretty sharp bend all at once. So, what's one to do?
Improve it....and replace the cats w high flow 200 cell sport cats, better tubing flow, using as much room as possible to improve the piping and angles....
