Yes this book is a must have if you want to know the history of the 1967 and the latest 2016 911R. Lots of information in this book. Total number of 911R in US is 296 copies. Two well known Rennlist members cars were featured in the book. First is unotaz’s car is on page 293. The second car is owned by a great enthusiast and engineer from New York which was heavily customized on pages 308-309 shown below.
Thanks for the mention GT3RS-Fan1. My build, in comparison to Robert's, pales in comparison! His Scarab Blue 911R is truly one of a kind and it shows the level of customization possible with Porsche Exclusive.

You're welcome Unotaz. Your build on your 911R I truly admire. Bob's on the other hand like you mentioned is impeccable. Bob's engineering background shows on the level of work he has done on the parts he has created for his 911R.
I can only imagine what customization you and Bob will do on your incoming GT2RS. Another cool project in the making.
Drive safe,

Track driving impressions - a 911R versus a 2016 911 GT3 RS on a race track
The RS is immediately at home on the track and feels completely bolted down. This is probably due to several factors - chassis geometry/alignment, tires, aero, calibration of RWS, etc. The RS is stable to the point that the driver can use very aggressive inputs (e.g., steering at corner entry) and the car just sticks. And its PDK gearbox allows shifts to maximize acceleration on short straights in a way that would be impossible with a manual gearbox.
Whereas the RS is bolted to the road, the R dances with an incredible agility – to the point that it is quite unstable on the track. The R’s softer suspension results in much greater weight transfer – both lateral and longitudinal, and its chassis settings are such (toe is set for agility over stability?) that it hops laterally everywhere under braking.
However, there is one area on the track where the RS cannot match the R, and that is in straight line speed. The 911R is easily able to pull several car lengths away from an RS on acceleration (50 to 140 mph). But gives it all back on braking and corner entry.
Compared to an RS, the R is a car more for pure fun than lap times. On the track, the R is a drift car, dancing all over the place and spinning up its rears at every opportunity. Twice the work but also twice the fun. The R remains an incredible car. Still enjoying it very much.
Thanks for the evocative comparison BusDriver. Sounds like the R is the one unless your ego demands the quickest lap time. It's like the thrill of watching the cars slither around in classic racing vs on-rails modern racing.
Will Porsche build another R before abandoning natural aspiration?

Agreed completely. Thank you!

and its the best (and cheapest) way how to "evolve" a fast car to a fun car.
Duplicating alignment settings from the 911R to the RS or Touring would be interesting and probably result in a looser car, but there is more to the complete package. For example, the R also has unique RWS calibration, unique damper settings, and the R's mechanical LSD has unique overrun and acceleration locking characteristics.
BTW, if I were trying to add agility to an RS or Touring, first thing would be to equip the car with ceramic brakes (if not already the case), then swap to lightweight forged wheels with appropriate tires, then perhaps a differently calibrated LSD, and only then iterate on alignment (incl corner balancing) to preference.
There is no easy or cost effective path to duplicate the factory hotrod 911R, but there are many ways to make an RS or Touring with a very personalized fun car.
Preuninger’s break-in recommendation is 5k rpm limit for the first 1000 km, then add 1k rpm. And every following 500km, add an additional 1k rpm. In the early days, most important to vary the rpm, not lug the engine, and avoid continuous high load operation. Also, as I mentioned earlier, after the first 500km the engine map changes to be a lot more aggressive – an insane bark at startup, and more aggressive throttle blips. At startup and idle, this thing reminds of a racing Ducati V-twin superbike.
The Sport button blips to smooths upshifts as well as downshifts. The only car that revs as quickly as an R with single-mass flywheel, is a Carrera GT. BTW, the GT4 engine has so much inertia that there is no comparison - I have never needed upshift blips in that car. And speaking of comparisons with the Carrera GT, the R sounds better inside and not as good from the outside, but still fantastic.
Compared to a current 991 GT3 RS, this car is a lot more special. Both for what it actually is, and for what it represents.
What it is, is a hot-rodded manual road-oriented version of the RS – lighter, slimmer, rawer, manual gears, light flywheel, etc. And from my experience of owning both cars, the R’s acceleration feels like that of a 550 hp RS. While the RS has the advantage of launch control and immediate gear shifts, the R accelerates noticeably harder within gear.
What it represents is, is what makes the R truly special. For me, the RS is simply the latest in a line of track weapons among which there is significant lineage in the form of every previous RS, and a number of alternatives – regular GT3, Speciale, 675 LT, etc. With the R, there is no previous version or obvious alternatives – if you want a raw hot-rod manual road weapon, there is nothing else even close. The R is almost as exciting as a CGT but a lot more fun without the grim reaper waiting to pounce at any wrong move.
The GT4 is a puppy, the CGT a lion, and the R a thoroughbred.
The GT3 Touring is improved and better than the R ... superior engine ... superior chassis ..more mid range torque ... with lightweight lithium battery and side muffler deletes drops 75 lbs so more agile ... all at 40% of current cost ... Kudos Porsche for moving the goal posts !!
911 R is not relevant as RS is best track car and GT3T best road car ... might seems like a good idea 30 years from now in some collection.

Sorry to bust this BIG hype bubble post ; )
I really do feel sorry for you; somewhere along the lines, something in your life must have really altered your path. I truly hope you find peace and happiness at some point

lowest spec GT3T is 1413 kgs ... R is 1370 ... half the diff is AC and radio delete. Inserting a lithium battery alone evens the weight ... from there the GT3T leaves the R in the history books and car collections as who would pay speculator price when they can have a superior road car for 40% of the cost and get to just relax and drive (stop over selling their car on these posts for financial rational) ... just the facts ; )
