The GT3 RS Porsche should have made


30 Aug 2011
Firstly I'll apologise now for this lengthy post. I feel it may however be of some benefit to anyone looking into future improvements for their RS, so a little intricacy and detail here and there, are thrown in for good measure :)

A little about my background: I suffer from a severe dose of spanner twirling syndrome and this rather an@l fascination with cars has led me into some interesting project cars in the past; from preparing lightweight track cars to running a 1.8l engined road-legal missile developing over 600bhp and many cars more besides.
A few pictures of some of my latest project cars:
A 2 year project to create a lightweight carbon clad Ring warrior. Every area of this car was heavily modified from Lexan windows to fully adjustable suspension components:







Also recently finished a little foray into the mysterious world of the Wankel (now for sale due to the GT3RS purchase, again an intensive exercise in attention to detail:




In 2011 I bought my first Porsche; well a 996.1 C2 with recent Hartech rebuild to be more precise. I set about from the onset tailoring this car to be just perfect. I wanted to retain the original styling cues but add an element of stealth sleeper into the equation, so a whole host of goodies have been slowly added since buying including: 997SSK, 200Cell cats, BMC filter with CAI, RSS engine mounts...








Now onto the main reason for this thread; I had been searching high and low, leaving no stone unturned, for the past 2 years or so trying to land the perfect 997.1 GT3RS. Well I finally found the right car and the fun in my man-cave is about to start all over again :mechanic: In fact the garage is a good place to start. Just to fit the Two 911's into the bloody thing caused a bit of a headache; I had so many large tools and bits and pieces that meant a serious clear-out was required. I removed the engine crane and other non-essentials into my cellar then fitted shelves all around which in total released around One meter extra width. I then tarted the place up a little with a few car related trinkets and some :porsche: memorabilia ready for the impending new arrival:

At this point I realised that the new car was going to cause me a bit of a headache as my driveway has a rather anti-sports car incline. The solution I came up with was to drop the first step to street level to allow a larger radius swing up the drive to hopefully prevent any potential lower lip scraping. My daughter Amira on-hand to help out:)



And the final result on the driveway front

Okay, with all the peripheral nonsense out the way onto the main course. The car I bought is a bit of one-off and not something I had come even remotely close to finding during my search. My initial feeling about the car was to walk away as nothing seemed to add up with the advertised information. I then decided to view the car, which was being sold on behalf of the owner by The official Radical Importer for Deutschland in Adenau (Nurburgring), Teichmann Racing (those keeping pace with the VLN race series will be very familiar with this company as they are one of the most renowned in the business; also the ring record holders with a 6:48min lap). The car has been serviced and modified throughout its life by Teichmann.

Here is a little video and a few pics of what they had in when I was last there :worship:




Upon my initial inspection I couldn't believe the condition of the car; it is literally like a brand new car. This type of car you normally associate with being thrown around a race track to within an inch of its life for its entire existence. When I looked a little deeper into the history of the car it was revealed that there were 3 owners from new, the first of which only had the car 10 months then an 80year old guy bought it. He was absolutely mental :lock: and probing a little deeper about this owner unearthed the reasons why the car is like it is today. As an example; when the Gen II was released, he got all upset that the later car had a bigger engine and more power. He decided to go to the above named Teichmann Racing to express his concerns with this little dilemma. Teichmann then commissioned Michael Kessels (a well-known Porsche Race engine builder) to build the 3.8l engine. He basically used only Porsche engine parts and built the 458bhp conversion. The engine was then sent to www.vgs-motorsport.com to have the ECU reconfigured with the new engine. The new engine has since only run about 5000km to boot :D
To give you an idea of how mental this old fellow was, he had the carbon seats wrapped in a black film along with the carbon door cards, he re-sprayed the brake calipers black... absolute mentalist :eek: He also drove the car almost daily like a complete fairy, hence, like I said before, the car is like new. During his ownership he put the car on an extensive diet consisting of mainly Carbon/Kevlar panels and a few other trick bits and pieces. I will describe each mod in turn below but effectively around €100,000 of parts have been fitted. There was a recent video posted here in which all the perceived flaws of the 997.1GT3 RS were highlighted. All the work which has been carried out on this car has addressed all of the weak points and then some.

Here is the video which highlights some of the issues (namely, understeer induced by a 235 section front tyre and Active dampers which rob the driver an element of feedback:

The car has the following modifications. (I have also added links/contact info so you can see where to buy them and also the price):

What a find!! An octogenarian former owner with more money than sense but a great taste in cars. Fantastic car, looking forward to more updates.

I bet there are no 80 year old owners in this country who would do all that to a GT3RS :nooo:

Keep us posted :thumb:
Excellent! Thanks for posting

This sounds like the equivalent to the extra lightened 996 RS car (the one with the long PARR work list)

...not sure how much additional spanner work you can do to this one...apart from returning to standard :hand:

I can think of a few things to get me started; again in the weight reduction department:
Removal of silly decal on front RH wing and the film covering the Carbon seats. This little lot should see at least a 10gram loss :grin:

I'm not familiar with the particular PARR 996 you mention but the way I see this car is as a perfect blend of all things good from the 996RS (raw, nimble, unearthly feedback) mixed with all the plus points from the Gen II (3.8l power, beautiful to the eye...) and to top it off a dry weigh of around 1150kg, more power than the Gen II and the crescendo from the Akrapovic Ti harmonics. What's not to like :)
It is just killing me now waiting to pick her up and to test if my driveway mods and garage shenanigans come good :D I should be picking it up sometime next week with all the corner weight and dyno printout data along with a new TUV.
Patience is a virtue and all that :what:
As it was meant to be

Just thought about the title and it actually has a second meaning to it....
As we all know lots of these cars are just garage queens or investor metal and it's not what Porsche designed them for!
Seems to me the op is going to be driving this awesome machine & good on him, just don't put too many miles on it dude :thumb: :thumb:
Collection day finally arrived and so another little trip to Adenau (Nurburgring) for the collection. Chosen attire for the day couldn't have been more appropriate; my brown trousers really came in handy for the semi slick excursions across the snow-laced Eifel wonderland :grin:
All ready outside Radical Deutschland/Teichmann racing:

First things first, my friend had lent me his trade plates so I drove all of 100meters to one of the best wine shops in Germany to buy him a little gift. If you are ever in this neck of the woods it is highly recommended. REWE is normally a Co-op type shop but this place has an incredible Whiskey/ Fine Wine selection. Probably the one and only time the car will be used for shopping duties :eek:

Next stop another 100meters down the road to the Aral Tankstelle (petrol station) for some of their finest 102RON magic. In fact you can see the Radical logo/sign in the distance so up to this point my understanding of all things Metzger are still in the Nappy wearing stage

It would have been rude not to; Faux glory shot. Honestly I did try but the Ring is now closed :D

Rear arches that make Vanessa Feltz look anorexic

CUP steering wheel. I even managed to get the original one thrown in as well

Here is a close up of the carbon door cards

Fairly spartan dash which doesn't even have that funny lap clock. Is this normal or another giant leap in the RS weight-saving department?

Doesn't show up too well in the picture but it looks like the car has just come off a rally SS with all the muck it has picked up

A quick 280km/h trial on Ze Autobahn :hand: now getting close to home so I drop down from the Eifel into the Vine clad Moselle valley


At this point the sudden realisation dawns; the car will get tucked away for the winter when I get home and all I will be left with are the short but sweet memories of this drive home. I decide to take a little scenic diversion onto some of my local favourite roads to prolong the pleasure :D





Get home and let the Mrs know why I haven't been sleeping for the last 3 weeks. Obviously she could not understand what all the fuss was all about but at least had the decency to not let her muddy gardening boots anywhere near the wafer-thin lightweight carpet set

As predicted, the CUP lip was a no-go item up the driveway so out came the jack :mechanic:

Whilst jacking the car I notice that the wheel arch liners have been eaten on the journey home (combination of wider front tyres/H&R adjustable coilovers) so one of my first jobs is to come up with a solution of creating the correct tyre to arch clearance.

Before getting tucked away for the winter the obligatory deep clean is the order of the day

Whilst wiping under the bonnet I took the battery cover off to see what battery was fitted. I then notice the Carbon strut brace. Is this a stock RS part?

Now all clean and ready for throwing in the garage




And a little video I managed to take of a 90-210Km/h run

So far I managed to collate a list of 18jobs that I need to do on the car so I'll keep you posted on the progress

What a find the car looks awesome doesn't it!
My only problem with it is I would have sleepless nights after purchasing it purely because I'd be in a constant dilemma about taking it on track..... But I'd have to that's what that car is built for. To add, these cars are fetching astronomical money at the mo in standard unmolested spec but I still think you've bought quite a special car ( the history the race spec etc) just goes to show you can find very very nice cars when you take your time looking... Well done and enjoy it!
Love it!

Pretty sure you can dump the strut brace, aren't the front towers braced to firewall anyway?

Loving the door cards also.
It would seem that the winter garage sports have started :)
As mentioned earlier I have a big list of fine tuning that I want to do to make this car perfect. There are a few differences with this car that I have to be wary of for instance: most of the panels are composite so you really need to be extra careful not to damage anything.
The first job I did was to remove the decal from the front R/H wing. I used a heat gun and then some WD40 to remove the residue. This technique seemed to work a treat.


Next up I could see that the R/H headlight seal was not properly seated. I removed the unit them reinstalled with the seal correctly located.

Whilst the light was out I took a picture showing the detail of the carbon wings. They really are made to an incredibly high quality, even the intricate, non-visible areas are finished to the same exacting standard.

I then started to investigate the scrubbing on the front arches. This ended up being a total nightmare to resolve and has taken me about 7hours so far just to sort the R/H side.
As I work alone and don't have access to a perfect workshop I end up making my own tools et cetera to find a solutions to lone worker issues. In this case I wanted to be able to turn the steering wheel on the ground without the PAS. To do this I used a trick that we use in aviation for Nose landing gear functional tests. First I found some sheet steel, I cut this into 4 equal parts.


Then a dollop of grease in the middle and there you go a low friction surface to allow steering checks.



I took numerous measurement and found that I needed to create about 18mm of clearance between the forward arch liner and wheel for when >360° of lock is applied inboard. I ended up having to disassemble the whole front end of the car and ended up modifying the radiator attachment brackets so that the correct clearance could be achieved. An utter PITA; this involved a slight trimming of the Carbon wings and elongation of a few attachment point holes in the steel brackets. I still haven't refitted the front bumper so there may be an element of rad surround trimming required upon refitting. I'll update later when I get to that stage. Here are a few pictures to give an idea of the work involved.









Here is a little trick I used to hold the radiator up whilst the support bracket was removed

Rad support bracket now off

Support bracket refitted and tested again with wheel fitted. Was really happy with this solution and now have the correct clearance :D

This is basically where I have left it for the night. Still the L/H side to do then the rebuild. The only other job I did was to clean the OEM Alcantara steering wheel.

And a comparison picture to show the difference halfway through
Another day spent working on the car today. Really wanted to get the car off the jacks so my main effort concentrated on getting the L/H front arch sorted.

This picture gives an idea of the solution I came up for moving the radiator forward (which the arch liner mounts onto the back of). After remounting I then sprayed the whole area with a CPC (corrosion preventative control called Dinitrol) this is the brown bubbly substance.

My car has studs rather than bolts on the hubs. Is this normal for the RS? The Porsche tool kit in the front compartment has 2 of the wheel removal alloy threaded rods so my guess is they normally have wheel bolts rather than studs???

View from L/H side behind the radiator from below looking up into arch

Next up the tail pipes were given a bit of a clean



The arch work has done the trick so after a few tests the car is now left on the C-Tek and covered up until my next bout of wife avoidance :grin:

Today I thought I would remove the film from the back of the seats. I was assuming that I would be done in 1hour; how wrong could I be. Absolute nightmare of a job. I had a niggling feeling that the reason these carbon seats were covered must be to hide something nasty. I just couldn't understand why this 80 year old former owner would pay someone to cover the stunning finish with some horrible matt black film. Due to the blisters on my fingers from doing this job I only managed to do one seat (6 bloody hours just for this one seat). Problem is that the film is a real pain to get off and then it also leaves some adhesive residue in places. I didn't want to use any abrasive substances so this took some time. The results are superb and the seat is like new. The pictures will tell the story better than I can.
Removal of lower forward roll cage bar

Seat out (if you ever do this be careful to undo the electrical connector on the bottom of the seat).

Seat out

Strip the seat

About 3 hours just to get this amount of film off

Almost there

All done

And refitted

Can't wait to do the other side :roll:
