911T Chrono Package and Rear axle steering ?

Porsche website, when describing Sport Chrono, only mentions Launch Control in conjunction with PDK.

Its not an actual "launch control" function in the manual. Its a rev limiter that keeps it at 4200 rpm with the clutch depressed and the throttle floored. Its programmed to do this to protect the transmission, but it is in fact a poor man's launch control. Confirmed with service dept. You're not supposed to do it alot because its not a wet clutch and you can damage it more easily than the PDK. So, its not advertised.
On a side note. Some magazines have alluded to the fact that the manual "only launches at 4k rpm" vs 6500 for the pdk, and thats one of the reasons its slower I still think the main reason is humans just cant shift gears as fast and you need to come off throttle to switch to second gear, which means you lose boost.

Wasn't aware that chrono was standard on the T, that's really cool. I say screw the clock then, it robs visibility at this point.. When are you ever going to use the track app and how often?

I wont track the car. I dont have sufficient track experience and I have two little daughters that love their daddy.

Ah, thanks.
And I agree about the fractionally longer 0-62 time for the manual, as no mortal human can change from 1st to 2nd as quickly as the PDK, not that 0.3 seconds bothers me in the least.

In real life I expect the PDK difference would be significantly more than 0.3s as the manual figures are the best achieved in ideal conditions by experienced drivers with unlimited (brutal) attempts vs. the PDK which does it perfectly every time. Again, I think most of us bought our cars for driving pleasure as opposed to statistics, so who cares unless you’re a drag racer - both cars are at the upper end of quick for use on public roads...

Configuring my T build (locks at end of month), trying to figure out if I need these. I probably wont track the car but I am going to drive hard, guaranteed.
1. Chrono Package icw track precision app - $320:
" Analog and digital chronograph - a chronometer installed on top of the dashboard can be used for timing laps, and can be configured as a clock when not actively used as a stopwatch.
Porsche Track Precision App functionality (may not be compatible with all mobile devices or service providers)"
I know almost all of the sport chrono functionality is standard on the T : adjustable driveline mounts, sport plus (throttle mapping), and rev match etc. Sport plus may also have a "launch mode"- 4200 rpm rev limiter (even though manuals dont get the "Launch control active" on the dash like PDK). I like the look of the flat dash, but dont wanna lose any ECU/TCU functionality if I don't spec the "Chrono package". Just making sure its just the clock and track app readiness. Anyone have any ideas??
2. Rear axle steering - $2090 ... self explanatory.
Do you really need this with the LSD /driveline mounts/ and SPASM with the base carrera engine? I bought 20' wheels for the winter set, so I should be good for clearance. Worried it might rob some of the 911 driving character if I got it.

As for rear axle steering -- Obviously if Porsche feels this component has tested well on the car and even charges 2 percent of the MSRP to have it then it's bound to add benefit. On the other hand even a zero option stripped car will still drive in a world class category . Let the wallet decide !!

1) 320 bucks is pennies on a 100K car to erase any doubt . Not a necessity but cant hurt anything.

Rear axle steering unfortunately might not happen.. as things stand. Im spending more $ for a better winter wheel set with N0 or N1 spec Michelin Alpins so I can confidently drive this bad boy 360-365 days a year. I still plan on back to back drives with two C2Ss with and without RAS before the build locks. I might love it.
The $320 is in fact "peanuts" but I love a slick dash without the hooter in the middle. If alex is correct and the clock has been separated from the package for "weight savings" then i really want to skip it. This is the only car other than the GT series that gets the chrono pack parceled out like this (with the important bits standard).
Always nice to have you chime in Cant wait to get it delivery is set first week of July.

Curious if RAS helps alleviate wheel hop at slow speed cornering (pulling into driveways/etc)? If so I’d probably spec it for that alone. Myself for 300$ I’d spec crono but I like the look of it.

I think my wallet has pimp slapped me multiple times daily... LOL

Here's a theoretical question, and possibly not pertienent. If you hit a pothole and the RAS breaks, does it get covered on warranty or is it "wear and tear"?

Not sure, is it possible to damage the rear steer components with this type of impact? Just asking out of ignorance.
#44
You would probably hit the pothole with the front tires first, so there would be plenty of things to go wrong. Maybe your comprehensive insurance would cover severe pothole damage? Not the dealers’ responsibility to fix stuff that you break.
#45
I would guess that if it was a hard enough impact to mess up the RAS, the tyre would be history along with the rim and possibly other suspension components. The RAS part of it would probably be the cheapest out of that lot to repair/replace...
