nice work guys. but i do have some questions.
1. you mentioned full on race mods on a street car. why not just buy a cup car. i have had a whole load of GT3's and some have had modest mods for track and they each have about 8-9000 track only miles. there is NO REASON to go full on race kits of anything on a street car.
2. i have used brembo GTR, and almost all variants of stop tech, they have their forte for sure, but not always better than oem. the GTR has such strong bite that it's modulation is not comparable to oem. which one is better really depends on driving style.
3. you mentioned pagid RS4-4 orange. if you even had modest mods on track cars, orange will not give you enough bite on such a heavy car. you really need RS19, 29 or 14.
otherwise very cool machine. hope to see it on track soon. what group you guys run with on nor cal tracks? i am on some track every weekend.

The result is pretty...nice, tight, great fitment, and a sound that you can't mistake in any way...yet, fully streetable or trackable...your choice, nice or mean.
Now, how does it really compare w the OEM set...here's a pic of the two sets on the car side by side....OEM on the left, GMG Sport headers and Cats on the right
Here's how they look fully installed....
And, the quick eye will pick up that we needed a full system, not just the awesome sport headers and cats....we needed a new center section. But, rather than just be another set of pipes and crossovers, w a set of tips that look hung on, or a wart on the whole solution, a great solution is truly an engineering piece of work, to integrate completely, and produce a flow and expansion to allow that wonderful sound to escape...
the tips look awesome...and fully align w the character of the car.
So, only one more step to go in the build before this weekend.
We now have -
Carbon Fiber sport seats
GMG harness bar/roll bar/shock tower brace
Willans dual 6-point harness sets
BRracing graphics
GMG suspension pieces, bushings, links, sway bars
GT3 Cup front splitter
GT3 Cup alignment (just finished a new alignment today)
Chase Cam video and data acq system
Go PRO HD video system
GMG sport headers and sport cats
GMG exhaust center section and tips
Stoptech STR60 braking system
PFC combo pad setup (O1 and 97 together)
We haven't decided yet on tires for this weekend (could be Toyo R888, Hoosiers, Mich, or Pirelli's)....full race slicks will come later when we complete the race suspension.
And...if you wonder if these little suspension pieces make any difference, even just for street usage, just wait for another post to come on another customer car (997 TT) that we complete today, and the transformation that the customer witnessed......he was truly amazed....but more on that in another post
One more piece to go before this weekend.
But, we want this to be a DEVELOPMENT car...we're here to test and prove what you want on your own cars, and we want to push the envelope. So, if you see or think there is another piece that is needed that is consistent w the build philosophy for this project....post here and let us know. We're not building a full CUP car, you can buy one of those. But, we want to see if we can refine the complete package into something more, so let us know.
Such FUN...

We will be at Thunderhill this weekend (Saturday Nov 14th), as we are also both instructors for Hooked On Driving, and will be doing both testing and instruction this weekend....plus will be there w a host of our customers out to play and learn how to get the most out of their cars.

To answer Mooty
(1) why not buy a cup car.....because we already have those. As part of a shop, we believe our role is to evaluate, push, and test the various options on the new cars to help our customers everywhere understand what works, what doesn't, why we choose the solutions we did. The new 2010 997.2 GT3 offers such a fresh canvas to play with, that it demanded attention and focus. And, we believe the GT3 will be a more broadly adopted solution by users, and we want to have been there for them....
(2) Brakes...all are great. But the success we have had recently w the Stoptech in racing, ALMS-C or SWC-GT class, we needed to try the new STR-60 setup for the 2010 GT3. We'll all know what the OEMs will do...but we need to try and test what we believe could be a good upgrade to determine if the results are really there.
(3) Pads...we have tried different pad sets, as we will recommend different pad sets for different customers...some are relatively new to tracking, some are very advanced, and we continue to play w multiple sets so that we again can have direct, track proven knowledge of what works and how, so that we can offer the best feedback and advice as possible. That's why our new 2010 GT3 will see the track this weekend....and we'll be doing data acq as well, so that we can really see the results and experience them.
But, let us know what else you think needs to be part of this project, consistent w the project goals....

OK....here is the last step in the build before tomorrow's track day exercise. And, in driving the car around the street, this car really needs to get out and stretch it's legs, but, boy, what fun when you get on this thing, the sound is incredibly intoxicating.
So, to have some fun with this next step in the build process, we have taken the first photo of what we are adding to the car.
Want to see if anyone can guess what this non-standard, special part is that we are adding to the GT3.....
What could this be?????
We won't keep the suspense going for too long, as the car needs to be packed up today in the transporter and taken to the track tonight so that we're ready for tomorrow bright and early.

Rep Power: 132 How was your M3? Brakes OK? did you get some r-compound? You can get a set of Toyo R888 for your 19" wheel. They come in 235/35/19 for front and 265/30/19 for rear. You can drive it on the street too

gt3 got a flat after a few laps.
same story on the m3. i don't want keep getting rock chips on my 19" RAC wheels. i'm waiting for some TRmotorsport MT1 18" square setup. they are still backorder till Dec. probably won't get them in time for laguna seca either.

BRracing 2010 GT3 next step
Well, two updates due. The first is the result of the addition and the answer to the teaser of what that last pic was and the piece that we were adding.
The answer is a new rear decklid and rear wing.
We took the current 2010 997.2 GT3 rear deck lid, the inside portion, and mated it to a 2009 997.1 GT3 Cup Car top deck lid, Cup Car uprights, and then a Cup Car rear wing. To this, we then added new CF air scoops on top, and had them fully molded in to the top cover. The new scoops increase airflow by 30%, and these are currently available items (but not a straight bolt on piece for the 997.2......yet).
The result is the package we've been working towards.....we had the guests guessing at TH as to what this car was...but the current wing on the car is the giveaway...as the new 2010 Cup Car has a much bigger wing than this.
The first pic is the new decklid, fully molded scoops into the top (which are CF, and we left a portion of the scoops exposed so that you can see the CF element).
The next pic is the full kit installed...the new rear decklid, the rear Cup Car uprights, and the Cup car rear wing (we are missing a new CF wicker...to be added soon).
The car was willing, the crew prepared, the driver anxious to see what we had created (Robb and Bruce would be the team drivers for the test).....

Track test update - BRracing GT3
I can't begin to explain the excitement we felt after we unloaded the car, and had participated in the normal track day preparations...we were ready.
We had just heard of a horror story about another new 2010 GT3 and a braking issue...will post that question here in just a sec, so we were going to start at about 90% just to make sure all was good.
But, on the very first track session, one of the cars in the group had done two things...first, had spun and kicked a lot of dirt back onto the track, and a car had obviously had some mechanical issue, as there was a piece of metal on the track as well. We don't know if they were connected, but the combination made for some quick reactions, and in trying to drive thru the stuff, we hit the metal piece on the rear tire, and immediately punctured the right rear tire...not a small leak, but a complete BANG.
We knew what it was as soon as it happened, and we were able to get the car back to the pits without any body damage in any way.
But...what a disappointment. First session, beautiful weather, great group, great track conditions, and no right rear tire.
With the new wheels and tires, and the new wheels being produced, we did not purchase spares yet (we will have two full sets of spares...but did not for this first track outing). In over 16 years of racing, we have never had this happen, but there is always a first...and this was a first for us.
So, we used the rest of the day to test the BRracing BMW 135i that also had some new parts to evaluate.....oh well
