friend was racing at the weekend in vln in a 997 cup and his mate was driving the standard 997 rs....he said the car was 20 seconds off a 997 cup car around the ring...!! very impressive indeed

Check the results of the first 4hr race:
http://www.vln.de/rennen.gb.php#
They came in 3rd in SP7 with a best lap of 9:01. Behind a 997 Cup with best lap of 8:38 and a Ferrari 430 GT, best lap of 8:28 and driven by our fellow Leh Keen! and Dominik Farnbacher.
There's another thread on the ABS "issue" and this is the best comment that summarizes everything:
https://rennlist.com/forums/7433213-post65.html
..and the part that I fully agree with:
"his is ALSO why you find a notable difference between hammering the pedal hard vs. ramping pressure in smoothly. When you give the brakes what I like to refer as the "high hard one" - fast, hard, spike apply - the wheels go quickly to lock, and the ABS is more prone to think it's on a lower-mu surface. When you squeeze into the brakes, and give the wheel a little more time to develop slip, this is less likely to cause underestimation of the surface grip/mu available.
Unfortunately, this is not really the ideal way to brake an ABS-equipped car on the racetrack; the faster you get to locking pressure, the later you can brake and the shorter the stopping distance. If your cars were stock, you should be able to brake like that.
So clearly - the cheapest solution will be to learn to threshold brake. "
It works for me in the racecar with 1000#s springs. You CAN'T do the "brake stab caveman autocross braking" technique. I'm amazed that in this topic what people are requesting is a driver aid that manages the braking for them so that the brake pedal works as a "digital" switch. The Motorsport ABS will do that for you. I've driven it in another Cayman built exactly like mine, but the stock ABS can work if you treat the pedal as an analog progressive control.
And yes, the softer your setup the easier it is to modulate (or the stiffer the hardest). Yesterday, with the Rain setup at Road Atlanta, in the few dryer spots you could be more "brutal" with the brake pedal with little consequences.
So squeeze, don't stab, or spend some $.

Great find cgomez, and I agree on the braking technique.
So, the 2010 GT3 RS on slicks is still 2.5 secs slower than the 997 GT3 Cup every 60 secs, despite the factory effort on the street 2010 GT3 RS preparation.
A 2010 GT3 Cup should be able to lap the Nurburgring under 7 minutes.
It is good to see Leh Keen going International !!!

I would love to believe it but something just tells me NAY!

Just search any Vid in youtube of a full lap of a VLN Cup Car and subtract the time it takes to go round the GP circuit section.

Well, in any case for the nay sayers, this past weekend, the 997 GT3 Cup that beat Walter Rohrl/Horst Von Saurma/Chris Harris 2010 GT3 RS street car, had a fast lap of 8:38.85 as mentioned by cgomez and shown in the results.
The fastest race lap in the VLN race at the Nurburgrung in 2008 by the Raeder Racing Gallardo was a 8:32.889 (barely 6 secs faster than the 2010 GT3 Cup). This same Gallardo was independently tested by Horst Von Saurma (Sport Auto Magazine from Germany, and Rohrl's co-driver this year), and they lapped the Nurburgring in 6:44, add less than 6 seconds to that time, and do the math for a 2010 GT3 Cup.
Don't mess with a well driven GT3 Cup of any flavor (from the 1998 360 Hp 996 GT3 Cup to the 2010 450Hp GT3 Cup) with a street car, unless you have built a track weapon out of a street car. Just look at what Leh Keen (he ran the 2nd place F430 GTC at the VLN race this past weekend) did to the field of GT2 ALMS cars with a lousy and stock 2010 GT3 Cup.

Behind the Manthey winner:
On Chris Harris own words, the VLN lap is 1:40 to 1:50 slower than the Nurburgring lap.
Rohrl ran a fast lap of 9:01 in the VLN race, so this 2010 GT3 RS equipped with Michelin Cup 18" slicks, and some minor tweaks is capable of a 7:11 to 7:21 lap time around the Nurburgring.
The 2010 GT3 Cup ran a 8:38 in the VLN race, so it is capable of running a 6:48 to a 6:58 (under 7 minutes) lap at the Nurburgring.
