As a testament to the incredible natural poise the GT3 RS possesses, this footage shows how well it fares against an already-potent M4 with a slew of modifications and a talented driver. Some might regard this as an unfair match, a track car against a mildly-tuned grand tourer, but it’s actually a closely run battle between two focused machines with slightly different repertoires.
Clearly, the BMW, tuned by French outfit Devotec, is the slower of the two from the get-go. However, add a set of 295-section Pirelli Trofeo R tires (they appear to be a bit stickier than the Porsche’s Pilot Sport Cup 2 tires) and KW Clubsport V3 coilovers, and the overall grip of the Bimmer is roughly on-par with the Porsche—at least in the some sections. In slower bends, like Adenauer Forst (2:37). the BMW shows a subtle amount of oversteer. It’s still quick, but it cannot compete with the rear-engine traction of the RS in pursuit.
Though the M4’s oversteer is manageable, it’s significant enough to allow the GT3 RS to claw back any distance in slow or off-camber bends.
Another area where the BMW is lacking is the braking zone. Crucially, the BMW tips the scales at 3,600 pounds, but AP Racing Pro 5000 R brakes and Pagid RSL1 pads help the car decelerate repeatedly and confidently. Yet, the Porsche’s weight distribution and svelte frame give it an advantage in every heavy braking zone.
So, where does the BMW have an advantage? After all, the Nürburgring is made up of tight, technical sections. The answer is in the high-speed portions of the track, where a tuned engine and turbocharged torque help equal the playing field.
The M4 can stretch a small lead once the course straightens, thanks to its aerodynamic additions as well as a whopping 553 lb-ft of torque and 580 horsepower. Not only is it the better dragster from 60-120, but it shows almost as much speed through high-speed sections, like Fuchsröhre (2:10). If ever there was a doubt about the relative skills of the drivers, it’s evident from the aforementioned section that they’re equally precise and courageous.
In conclusion, it shows that on stickier tires and with more power, the M4 is as potent on the ‘Ring as the Porsche. I’ll refrain from a diplomatic sendoff: points for power go to the BMW, but for low and mid-speed brilliance, the RS is the clear winner, and not much slower once the course straightens.
It’s safe to say the King hasn’t yet relinquished the throne.

Love that sound.
I've owned Porsches for more than 30 years, BMW's as well...and in complete honesty, for me BMW's are more enjoyable and drive-able at, or near their limit. My late wife Carole and I collected our Polar silver 993C4 in Stuttgart and proceeded to cover 5,200kms (many at 290kmh) in just 8 days.....including more than a few laps around the Nordschleife, Spa-Franchorchamps in the wet, as well as crossing both the Stelvio and St.Mary's Alpine passes...before returning to Stuttgart for shipping to the U.S. Needless to say that 993 will forever be loved and treasured. However I feel Porsche lost their way with liquid cooled cars..the crappy interior quality that first debuted with 996 and 986's...poorly engineered cooling systems...horrific reliability issues...and a general loss of 'soul'.
BMW's M3/4 coupes are pretty 'special' these days, while post 993 Porches are just new Porsches...but lacking that unique 911 feel, soul, and passion. Honestly, down here on Florida's 'Suncoast' 996's/997's/981's et al are like Toyota's. They're everywhere, driven poorly by those who leased or bought only because they could. Fashion or status statements, nothing more. Sadly boys and girls..it ain't Ferry Porsche's sportscar company anymore ...
Fast911ray sounds like you have had a good life but i beg to disagree you should jump in a GT3 or a GT3RS and if you are lucky enough a GT2RS for a test drive, you won't go back to a BMW. Cheers.
