You guys are missing my point. I know factory pro driver for porsche did the lap faster. An apples to apples comparison is sports auto because its the same driver, same rules (fastest of 3 laps)/stock car with no “Special Porsche Pit Crew Modifications” ahem ahem you know what I mean.

C7 Z06 is a 7 year old car and that same driver did it 7:13, and that was a manual transmission stage 2 aero car (so not their most track version).

Underwhelming time for GT4RS given its how much newer, has much better tires, engine, tech, PDK, etc etc.

Well the Z06 had 650 HP/TQ, more tire and brake, better suspension, stability management, etc. so that’s a lot of physics to overcome.

Yes l do see what you're saying but lm looking at it from a more realistic angle, the Vette accomplished that time way back in 2016 when the track was much shorter, the same driver did it at a much longer Nurburgring in 4RS, so there's a difference of around 5 seconds which would put the 4RS ahead like for like.

Anyway whichever way you look at it the 4RS will be the most exciting, exhilarating "FUN' car to drive on and off the track. That's what really counts in my books.

THIS! Who cares about what time a pro race driver gets around NBR in it. I’d probably not be comfortable doing it faster than 9 minutes anyway. The longer it takes you around, the more funtime you get😎

I am not sure i think 991.2 GT3 RS is still more exciting at all

Corvette has racing legacy with an enviable winning history.

We should not dismiss the virtue of Corvette.

Except it isn't. Unless you're driving at the same exact time, there are always other variables. Lap times on 2 mile tracks can increase by over a second from the start of the day to the end of the day. Now factor in a 14 mile track with as many corners as it does....and on completely different days with unknown conditions.

The racers in this thread will get what I'm talking about.

Anyone know what the spring rates are on the GT4RS?

GT4 production date is July, Hoping we can get to the Nuremberg Ring this year with it.

Irish Green PCCB leather.

Also have a Z06 coming next year and now this just popped up in my Porsche app.

Do we know yet if the changes to the 4RS' suspension do anything to decrease bump steer and specifically to mitigate rear toe deviation on compression/rebound?

I'm aware of new toe links and stiffer springs/dampers. The stiffer springs/dampers should help as long as there's a good amount of added compression in the front, rebound in the back, increased spring rate overall, caster adjustability to keep the track at original levels during alignment, and minimized deflection at the toe links. With that said, it seems like the toe deviation problem on the 982 all originates from the linearity (or lack thereof) of its toe response curve to suspension travel.
